Once you have connected your camera to the computer and opened the Envisage program, you’ll want to start 

taking pictures. Follow the steps below to start taking simple pictures with your Deep Sky Imager camera. We 

recommend that the first time you take pictures, you do so during daylight hours. Point your telescope at a 

stationary landmark, such as a building, telephone pole or so forth—trees and other objects that move slightly 

are not the best objects to use during your first 

image tests. 

1. Click on the “Auto Exp” button (3). 

See “Auto Exp Button,” page 19, for 

more information. 

2. Click on the combo box controls in the “Image 

Process” field (10) to display a list of object types. 

Scroll down the list and select “Terrestrial.” See 

“Image Process,” page 21, for more information. 

3. Type a name for the object in the “Object 

Name” box (11). This will be used as the image 

file name. See “Object Name,” page 22, for 


4. Click “Save Process” button (13). Select “JPEG” 

and “Normal Operation.” See “Save Process,” 

page 22, for more information. 

5. Click on the “Live” tab (17). See “Live Image 

Check Box,” page 19, for more information.

6. An image should be already displayed on the screen (39). Use the focuser on 

your telescope to focus the object. See “Magic Eye Focus,” page 25 for more 

information about focusing. If you are having a lot of problems focusing your 

image, see “The Parfocal Ring,” pages 17-18. 

7. Click “Start (14).” 

The camera begins taking pictures and will 

continue to do so until you click on “Stop.” 

Watch the Status box (24). When “Images” 

reaches 50, click the “Stop” button (14). 

Start Taking Pictures 2 

Go to the next page to find out what the program is doing once you press “Start.” 

11

What Happens When You Press Start 1 

• The live image is displayed on the program’s display screen if the Live box is checked and the Live tab is 

selected (these are the default settings). 

• When you press Start, the Deep Sky Imager camera begins taking images and continues to take images 

until you press stop. The Envisage program uses the first 10 images it takes as a baseline to compare with 

the images it takes subsequently. In other words, the program is always comparing images. Note: The user 

can change the amount of images that the program uses as a baseline. See “Evaluation Count,” page 21, 

for more information. 

• The program takes images with the best contrast and quality and assembles the best of these images (that 

is, the program “stacks the best images”) into one image; this image is referred to as the composite image 

in this manual. 

• After you press the Start button, the composite image is displayed as a new tab above the display screen. 

When you press Stop and select this tab, the final version of the composite image is displayed. 

• After about 10 images are taken, the Envisage program applies a sharpening filter to the composite image. 

You can choose which sharpening filter you wish to use from the most to the least sharp, or none. You can 

change the filter setting while the camera is taking pictures. See “Kernel Filter,” page 21, for 


• Further image enhancement or filtering may be performed in other image editing software, such as the 

supplied Image Processing software or Adobe ® Photoshop. Make sure you select an image type that can be 

opened (such as JPEG or BMP) by the Image Editing software.

12

What Happens When You Press Start 2 

• The Envisage program is continually resaving the composite image. If the Save Every Composite Image box 

is selected, in the Save Option dialog the program will save every image that added to the composite image 

(see page 22 for more information). If your PC crashes or loses power, the images that have been taken up 

to the time of the crash or power loss will automatically be saved—the user does not need to save them 

manually. 

• The Envisage program continues to composite the image until you press the Stop button. Typically, about 50 

images are needed to get a high quality composite image. After 50 images, the quality of the image 

increases only in small amounts; about 90% of the quality level will have been accumulated with about 50 

images. 

• When you press Start again, the Envisage program begins to accumulate a new composite image and 

renames the image in a new tab. For example, if you named the first image “Building,” the next images will 

be named “Building 0002,” then “Building 0003” and so forth, so that it doesn’t overwrite the previously 

saved images. 

• If a name/number was previously saved as a file name, the program will choose the next available number. 

For example, if “Building 0007” was previously saved, the next file will be named “Building 0008.” 

• Note that controls that are not currently available are grayed out.

How to take a picture of a terrestrial 

object, the Moon or a planet 

1. Insert camera into the telescope as previously described. 

2. Click on the Live tab (17). 

3. Click Auto Exp (3). The program will find a good exposure automatically. Set the image balance according to 

your taste using the Contrast (21) and Color Balance (8) [color models only] controls. 

4. Use Shadow Enhance if necessary. This control is excellent for the moons of Jupiter, craters of the Moon, 

some deep sky objects such as nebulae. 

5. Go to the Image Process box (10) and select the process from the pop up menu you wish to image (e.g., 

moon, planet, etc.). 

6. Click the Save Process button and a dialog box displays. Select file type. Typically you will select “jpeg.” If 

you wish to perform image processing in another program such as Photoshop, select “tif.” 

7. Draw a box around the planet or a bright feature of the object you wish to image. Or if the object is bright, 

choose a dark area, and check the Dark Spot box (40). 

8. Enter a name in the Object Name status. 

9. Click Start (14). The program will now begin to take images. 

14

An example of taking a picture 

of a deep sky object 

1. Insert camera into the telescope as previously described. 

2. Click on the Live tab (17). 

3. Set the Live Exp spin button to 1.0 second. 

4. Click Mono box (not available for Black and White models; continue on to the next step). You should 

see bright stars on the Live screen. 

5. Before taking the first shot of the evening, leave the camera sit for 5 to 10 minutes to allow the temperature 

of the camera to stabilize. 

6. In the Image Process dialog box, select “Take Darks.” Use the default values. Click the Start button. 

7. A warning displays prompting you to cover the telescope. Cover the end of your telescope so that no light 

can get in. Click OK when it is covered. 

8. The imager begins taking dark frames (see “Dark Frames” page 34, for more information). The Dark Frames 

are saved in the directory: C:Meade Images/Dark. The program will display how long the Dark Frame 

exposures will take. Important Note: Do not take dark frames while the camera is cooling off. 

9. When the Dark Frame exposures are completed, a dialog displays prompting you to uncover the telescope. 

Click OK. The Dark Subtract box (6) should be checked now; if not, do so now. 

10. Stars should be visible on the live tab screen. 

11. Select a star to image by drawing a box around it. If the telescope is connected you can use the telescope 

control (Arrow keys) to help choose a star. See “ Autoguiding and Telescope Controls,” page 31, for 


12. Adjust the focus by looking at the magic eye focus box, which is a 3D plot of the intensity of the selected 

star. Make the sides as sharp as possible. See page 25 for information on setting the magic eye focus. 

13. Check the Long Exp box (7). Set exposure to 15 seconds. This will allow you to take a preview of a single 

image to view an example of how the camera is imaging. 

14. Click Preview (2). The countdown timer counts down from 15 to zero seconds. 

15. You can now tweak the image. Uncheck mono box [not available for Black and White models; continue 

to step #17]. more...

16. Click Color to bring up the color control dialog. Then click “Auto WB.” Color image controls display [not 

available for Black and White models]. 

17. Adjust Autocontrast (21) and Shadow Enhance (21). 

17. In the Image Process menu (10), choose “Deep Sky.” Use the default values. 

18. Once you have a reasonable color or black and white image, type in a name in the Object Name box (11) 

Tip: If your object’s name contains a number, such as M31, add a dash after the number. The 

program Automatically saves each image with a number and the dash will allow your image names 

to be displayed as M31-0001, M31-0002, M31-0003, etc. 

19. Click Start (the button is then displayed as “Stop”). The imager begins taking pictures. 

20. The imager now takes 15 second images. Be patient. Take a number of pictures until your image looks good 

and click Stop to abort. You will now have an image that you can post on the web or submit to one of the 

Deep Sky Imager user groups. 

Experiment with Contrast, Shadow Enhance, Histogram sliders and Dark Subtract, and you will begin to take 

images like an expert. 

Dark Frame Subtraction takes out a lot of “hot” pixels from the image. Play with this control to see what effect it 

has on your image. 

Preview image without color balance or 

contrast (color model only). 

Preview image with color balance and 

contrast (color model only). 

Final image after 50 combined images 

(color model only).

The Parfocal Ring 1 

It is extremely useful to have the Deep Sky Imager camera and a telescope eyepiece be parfocal—it will save 

you time when you need to refocus. 

Parfocal means setting two or more eyepieces to the same focus. (In this case, one eyepiece is a camera.) In 

other words, if you focus one eyepiece in your telescope, then you remove it and replace it with a parfocal 

eyepiece, the parfocal eyepiece will require little, if any, refocusing. 

The following procedure will show you how to make your Deep Sky Imager camera parfocal with a low-power 

wide-field 25mm or 26mm eyepiece (do not perform this procedure with a high-power eyepiece). Use the 

supplied parfocal ring and perform the procedure during the daytime.

17

The Parfocal Ring 2 

1. Open the Envisage program. 

2. Insert the Deep Sky Imager camera into the telescope eyepiece holder. Do not tighten the eyepiece holder 

thumbscrew. Make sure the Deep Sky Imager camera slides down as far as it will go into the 

eyepiece holder. 

3. Point the telescope at a terrestrial object that has a lot of contrast with the surrounding area and if possible, 

has a distinctive edge (like a building, for example). 

4. If you have previously moved the histogram sliders, move the top slider to the 0 position (move all the way 

to the left) and move the bottom slider to the 256 position (move all the way to the right). 

5. Click on the Auto Exp (3) button. 

6. An image which may be or may not be focused appears on the 

display screen. 

7. Use the telescope’s focuser to get a rough focus of the object. Be patient. 

You may have to rotate the focuser back and forth until you can achieve 

focus of the image. 

8. When the image is roughly in focus, remove the camera from 

the 

eyepiece. 

9. Place the supplied parfocal ring over the bottom chrome tubing of the 

eyepiece. Do not tighten the ring. 

10. Place the eyepiece and tubing into the eyepiece holder. Do not tighten 

any of the thumbscrews yet. See photo at right. 

11. Do not use the telescope focuser in this step. Lift the eyepiece (but not the parfocal ring) until the object is 

focused. 

12. When the object is focused, tighten the parfocal ring. The eyepiece is now parfocal with the Deep Sky 

Imager camera. Do not remove or change the position of the parfocal ring or you will need to repeat 

the procedure. 

Now, instead of focusing the camera with the telescope focuser (which is somewhat difficult and time 

consuming), insert in the eye piece/parfocal assembly and focus the eyepiece as you normally would. Then 

remove the eyepiece and replace the camera. You’ll find that the camera is focused and may need only minor 

focuser adjustment. 

18

Automatic Adjustment Controls 1 

Gain and Offset sliders (1): Similar to a TV set’s contrast and brightness controls. These controls are 

automatically set after you pick an Object (10) type and click on the Auto Exp button (3). Most users will seldom, 

if ever, need to set these controls manually. 

Auto Exp. button (3): Automatically sets the Gain and Offset controls(1) for the camera. Before taking pictures, 

choose an Object (10) type and click on the Auto Exp button. This will adjust the camera to give you the typical 

contrast and brightness you need to take pictures for the type of object you have selected. You can further 

adjust the picture by adjusting the Histogram sliders (19), Filters (Kernel Filters, page 21, for more information) 

and focusing the telescope (see “Magic Eye Focus,” page 25, for more information). 

Mono check box (4) [grayed out and not available for the Black and White model]: Check this box to take a 

black and white picture. 

Live Image check box (17): Click to display live camera image in the Image Display (39). 

Dark Subtract check box (6): See “Dark Frames,” page 27, for more information. 

Color Dialog Cntl (Color Balance) (8) [grayed out and not available for the Black and White model]: Allows 

you to control your images’ color. It is recommended that you click “Auto WB” and then make further 

adjustments using the other controls. Auto automatically sets a color balance, balancing the red and blue values 

in relation to the green. Note: Once Auto is pressed, the values selected by Auto WB remain do not 

change, unless changed by the user—they are not continually updated by the program. When you begin 

a new image, it is recommended that you reset the values in the Color dialog. 

19

Color sliders [not available for the Black and White model]. Experiment with these sliders to change to 

change the image color. 

Sharp [not available for the Black and White model or DSI III] provides a sharper image, but the colors are 

less saturated. 

Soft [not available for the Black and White model or DSI III] provides more saturated colors. 

Daylight [not available for the Black and White model] provides a brighter image. Note that this may also be 

used for deep sky images. Experiment with this setting using the Preview Control (7). 

Reset [not available for the Black and White model] sets of the color sliders to midrange. This might be 

helpful if you wish to perform color correction in another image processing program, such as Adobe Photoshop. 

Long Exposure check box. Check this box to set a long exposure. If your telescope is only crudely aligned, set a 

value of no more than 15 seconds (this is a good starting value for any telescope to use) in the spin box to the 

left of this check box. 

How to take a long exposure: 

Turn off mono and click “Preview.” 

A countdown displays and the live check is turned off. 

An image displays. 

Automatic Adjustment Controls 2 

You can now use the color balance [not available for the Black and White model], focus, contrast, shadow 

enhance and auto contrast to adjust and manipulate the image. 

Once you have the preview sets the way you want your image, click on Start (14) and an image will be 

composited using your Long Exposure settings. 

Live check box. Check this box to set your live settings and focus. Check the Mono box [not available for the 

Black and White model] and set the spin box to the left of this check box to 1 sec. You will now have an 

image that you can easily focus using the Magic Eye focus controls (see Magic Eye Focus, page 25). 

20

Image Processing Controls 1 

Setting Menu (25): Click on the Setting Tab to display the Setting 

fields. These are field that may be filled in by the user, if so desired. 

It also contains the directory paths for the Images and Dark frames 

directories. 

Combine (9): Selects a minimum quality level that is acceptable 

when images are added together to produce the 

composite image. Typically 50% is selected. You may wish to set it 

lower (e.g., 30%) if you have an image that has a lot of turbulence 

or other noise, but should try adjusting other controls first, such as 

the Histogram sliders (19). Also try refocusing the telescope. 

Image Process (10): Displays a list of objects to view, such as Planets, the Moon, terrestrial, etc. Adjusts some 

of the image processing settings to preset levels that will assist you in better quality images for the selected 

object. Also “Take Dark” is on this list; see “Dark Frames,” page 34, for more information. 

Kernel Filter: The chosen sharpening filter is applied to the composite image as it is saved and is displayed in 

the live Display Image after about 10 images are accumulated. 3 levels of sharp filters, 1 edge only filter and 

“None” (no filter) are available. The settings for this filter appear when terrestrial or Moon is selected from the 

Image Process (10) list. 

Click on the Min Quality % spin box (9) to change the minimum quality level. 

Evaluation Count (9) allows you change number of images accumulated and 

evaluated to determine a quality baseline when the Start button is pressed. 

Normally, 10 images are evaluated (this is the default number). Click in the spin 

box to change the number of images used. 

21


Object Name (11): Type in a name for the object. Each time the Envisage program 

begins to accumulate a new composite image, it renumbers the image in a new tab, 

using your original name. For example, if you named the first image “Building,” the 

next images will be named “Building 2,” then “Building 3” and so forth, so that it 

doesn’t overwrite the previously saved images. If a name/number was previously saved as a file name, the 

program will choose the next available number. For example, if “Building 7” was previously saved, the next file 

will be named “Building 8” and will not overwrite the file “Building 7.” 

Save Process (13): Click on this button to select the type of file format in 

which to save your picture. Beginners are recommended to save their 

pictures in “Jpeg” format. However, if you wish to perform further image 

processing, select “BMP” or “Fits.” The last two formats, “Fits” and 

“Fits3P” are uncompressed formats, are for use by advanced users. “Tif” 

files usually take up the most memory, but may be a useful format if you 

plan to use Adobe Photoshop. See “Time-Lapse Settings,” page 27. 

Save Options (13): Normally images are added together make up a 

composite image or if they have too low of a quality level, they may be 

discarded. However, you may choose to save every composite image the camera creates by selecting Save 

Every Composite Image in the Save Options box. 

These images are not displayed as separate images; only the last saved composite image is displayed. These 

files are stored in the directory you have chosen using the Image Directory field or the default directory chosen 

by the program during installation. If you wish to view any of these files, Click on the File Open button (25), and 

then choose the file from the directory. 

If you set the Min Quality % box to zero (0), every picture will be saved. 

The number of images the camera takes is displayed in the Status Displays (12) and the name on the File 

Name tabs (17) change with each new composite picture. 

Start/Stop button (14): Press to start or stop the camera taking pictures. See “What Happens When You Press 

Start,” page12, for more information. 

22


Image Acquire Status bars (15): Display while the Deep Sky Imager camera is taking 

pictures. Also a box displays the images format (e.g., jpeg), type of operation, time-lapse 

sequence or other pertinent information.. 

Image Directory field and Browse button: Click on the Settings menu 

(25) to display a dialog box. In this box, click on the Browse button

Magic Eye Focus 

The Magic Eye Focus (22) displays a 3-D surface plot of the intensity of the image 

centered on the crosshairs of the tracking box (see page 28). As you adjust the focus, 

the peak of the plot will grow or shrink and the edges will grow steeper or less steep. 

Best focus is achieved at maximum peak and steepness. 

25

Connecting your Telescope and 

Telescope Controls 

To connect to your telescope, see the printed instruction sheet that was 

including with Autostar Suite. 

Once the telescope is connected, you may use the following controls (28): 

Use the Arrow keys to move the telescope. 

Click on an Arrow to move in that direction at Guide Speed. Hold and drag on an 

Arrow in the direction you wish to move to increase the speed. Hold and drag an 

arrow in the opposite direction to decrease speed. Release to stop. 

If your telescope has motorized focus, use the focus button to focus on the 

object (only one focus speed is available). 

26

Time-Lapse Settings 

Envisage software allows you to take time-lapse images of an object. 

This means you can set the software to take an image, wait and then 

take another image after a period of time goes by, and continue the 

process for however long you desire. This is ideal for taking images of 

clouds moving through the sky or creating an animation that shows the 

rotation of Jupiter (see “Making a Movie of the Rotation of Jupiter,” page 

36, for more a procedure on that topic). 

When you begin a time-lapse sequence, you can perform other tasks or 

go inside and catch up on your sleep. Envisage does all the work for you automatically. 

The setting for Time-Lapse sequencing are found in the Save Process dialog box. Choose “Save a Time-Lapse” 

Sequence” to use this feature. 

You will need to set three parameters for a time-lapse sequence: 

Frame Time: How long the image takes to acquire an image (be sure you know how your telescope can image 

an object—some telescopes can track for long periods, other will get a fuzzy image after perhaps 5 minutes— 

set your frame time accordingly). 

Wait Time: The amount of time the imager waits before taking the next picture; this is the amount of time it 

remains idle between images. It can be set to zero. 

Total Time: How long do you want the entire sequence to run.

Deep Sky Imager Camera Program 

Advanced Concepts 

28

Tracking Boxes and Centroids 

Drawing a tracking box allows you to track (that is, to follow) a bright spot that is surrounded by a dark area. 

This is very much like your telescope’s tracking feature. 

A centroid is the spot where the crosshairs meet. You can use the centroids to help you center an object in a 

box. The centroid is used for shifting an image before it is combined in a composite image, and also is used for 

autoguiding. 

To create a tracking box, just use the cursor to draw a box around an object. For your first tests of this feature, 

try to choose an object that is bright and has a dark area surrounding it. You can experiment with this as you get 

familiar with the function. 

If you’re tracking a crater on the moon, draw the box about the center or a bright spot in a crater. 

29

Histogram Display and Controls 

The Histogram controls allow you more control of the brightness, contrast and midrange 

tones of your Deep Sky Imager camera. 

Experiment with these controls. Select an easily focused terrestrial image and adjust the 

Histogram sliders. You will notice the Live image growing brighter or darker, and even 

notice mid-tones becoming more visible. You will have to adjust these sliders differently 

for each object and can adjust the sliders “on the fly” as you are creating a 

composite image. 

You can also use these control when you select Preview. When you return to the live 

image, it will apply the setting you choose while in the preview mode. 

Note: The effect of the sliders is saved in all file types. 

Autocontrast: Automatically sets the sliders for the best contrast. You can change the 

settings from 1 through 5 to set more contrast. Each number provides a higher level of 

contrast than the last; 5 is good for very dim objects. 

Shadow Enhance: Helps bring out details in the shadows (gamma). 

30

Autoguider and Telescope Controls 1 

For users familiar with the product, the Deep Sky Imager camera functions in a manner similar to the Meade 

Pictor 201XT CCD Autoguider. 

An autoguider helps keep an object centered so that a 35mm camera can take long exposures of an image. 

Note that you do not have to set the Deep Sky Imager camera for a long exposure using Exposure 

controls (2). Autoguiding is used typically with telescope mounted in the equatorial mode, although it 

can also be used with LX200GPS Telescope mounted in the alt/az mode. 

To use the Deep Sky Imager camera as an autoguider, perform the following procedure. You will need an 

off-axis guider (see the Meade General Catalog for more information) and the supplied serial cable that is 

appropriate for your model telescope. You will also need to know the focal length of your telescope. 

1. Attach the off-axis guider and your 35mm camera to your 

telescope as described in that product’s instruction manual. Insert 

and tighten the Deep Sky Imager into the eyepiece holder. 

2. Click on the Telescope tab. 

3. Attach one end of the serial cable to one of your PC’s comm ports and the 

other end to the telescope’s RS-232 port. 

4. Type in the comm port number into comm port box. 

5. Click the Connect button (it will then display “Disconnect”). The buttons 

below the Connect button become active and status data is displayed, such 

as which version of Autostar is connected, whether your telescope can 

Autoguide or just track, and so forth. If the telescope is capable of 

autoguiding, “Can AutoGuide” will display. 

6. Check to make sure your cable is properly attached, that you have the correct port 

number selected and so forth. If the telescope connection is verified, you will receive a “passed” message.

7. In the “FL IN MM” field (focal length in millimeters), type in the focal length, in millimeters, of your 

guide scope. 

8. Locate a star using your telescope’s alignment and Go To procedures. Focus and prepare the imager 

as described earlier in this manual. You may now use the arrow keys (28) to center the object you have 

chosen. Click on an arrow to move in that direction at Guide Speed. Hold and drag on an arrow in the 

direction you wish to move to increase the speed. Hold and drag an arrow in the opposite direction to 

decrease speed. Release to stop. 

9. If your telescope has motorized focus, use the focus button to focus on the object (only one focus speed is 

available). 

10. Draw a tracking box around the star. 

11. Click the Track Here button (the button then displays “Tracking”). Will Cal displays on the Calibrate button. 

12. When you click on the Track Here button (you do not need to press the Will Cal button), the program begins 

to calibrate. It then begins to autoguide your telescope and displays X and Y error coordinates in the Status 

Display box (24). When the program is done calibrating, it will start tracking and a yellow circle will appear 

on your target object. 

13. Click the Tracking button (the button then displays “Track Here” again) to stop tracking. 

If you don’t move your telescope or rotate the guider assembly, you do not need to recalibrate. However, if you 

wish to recalibrate, click on the No Cal button to force it to calibrate (which will then display “Will Cal”). 

The Track Last button will start tracking from where it was (the last tracking position) before it was stopped. 

32

Other Features 


Center Target: Click Center Target to move the yellow circle to the center of the screen. The telescope models 

will follow (some telescopes will move more slowly than others). 

Set Target: Click Set Target and click on a position on the screen. The target will move to the this position. 

Corr (Correction) Gain: Sets how aggressive the correction operates. Default setting is 0.5. .01 is the lowest and 

1.0 is the highest setting. 

If your telescope takes too long to reach to the yellow circle, increase the gain. 

If you telescope keeps overshooting the yellow circle, moving back and forth, decrease the gain. 

If the telescope never reaches the yellow circle, recalibrate: Click the Tracking and No-Cal buttons. Then click 

the Track button again.

Some Words about Dark Frames 

In oil painting, it is important to prepare the surface of the canvas to receive the paint. The unfinished surface of 

the canvas is not conducive to the fine brushstrokes required for fine art. The surface may have fabric strings or 

grainy bumps that will distort the finished picture. Canvas preparation is accomplished by applying oil gesso 

with broad regular strokes in one direction. After drying for several days the artist sands the surface until 

smooth and repeats the gessoing process as needed to achieve a smooth surface. Only then is the canvas 

ready for the artist to begin. 

A similar process is needed for the Deep Sky Imager which can be thought of as a canvas for a fine painting, 

only in this case the canvas is the silicon surface of the imager. This silicon surface is uneven in a different way. 

If the Deep Sky Image sensor is covered to block all light for a period of time and the resulting image examined, 

you would expect it to be uniformly black, but it is not! This image, which is called a “dark frame”, is speckled 

with a pattern of dots of varying intensities. The brightest dots are called “hot pixels” and all of these are created 

by electrons leaking into the pixels due to heat or other means and not from exposure to light. This pattern is 

very predictable and changes only in intensity with time. If this “dark noise pattern” is not removed from the 

exposure it will add distortion to the picture. 

Fortunately, because “dark noise” is predictable, it can be subtracted from an exposure leaving a clear image. 

AutoStar Suite software performs these “dark noise” subtractions automatically for Meade imagers because they 

transfer complete and uncompressed images to the computer. 

Images from webcams can't apply “dark noise” subtraction. Why? Because they compress their data and are 

unable to create a “dark frame” for correcting the image. 

34

Dark Frames is a useful feature for if you’re taking exposures longer than 1 second. 

Longer exposures and temperature can create noise in your Deep Sky Imager camera called dark current 

artifacts. The Dark Frames feature allows you to subtract out some of this noise from your pictures. 

Delete Existing Dark Frames. Deletes and overwrites previously imaged dark frames. This is box is left 

unchecked as a default. 

Total Time. Displays how long it will take to create all the dark frames using the Dark Frame settings chosen by 

the user 

Perform the Dark Frames features at night. If the temperature changes 

significantly during your observing session, you should repeat this procedure. 

To perform the dark Frames procedure: 

1. Select “Take Dark” in the Image Process combo box (10). The Dark Frame Exposure controls display. 

2. Select a range of exposure time. For example, if the length of your exposures will be between 2 and 5 

seconds, set the First Exp (Exposure) box for 2 seconds and the Last Exp box for 5 seconds. The Envisage 

program will then take a series of dark frames image files between 2 seconds and 5 seconds in length at 

approximately 1 f/stop intervals. Later, when you set your camera exposure time (see Step 6 below), the 

Envisage program will automatically select the Dark Frame file with the closest exposure length, temperature 

and proper binning, and apply it to the image you are taking. In effect, it subtracts out the dark 

current 

artifacts.

3. Select a value for the Avg Exp box. This is the number of 

exposures that are averaged together to create each composite 

Dark Frame exposure. Typically, set this value to 10. 

4. Click on the Setting menu (25). The Dark Frames directory field 

displays. The Dark Frames will be saved to this directory. You 

may change the directory if you wish. 

5. Click the Start button (14). A message displays that tells you to 

cover up your telescope or Deep Sky Imager camera. Replacing 

the lens cap on your telescope is sufficient. 

The program erases all the old Dark Frames files in the directory 

if “Del existing darks” is checked. It then takes and saves the new Dark Frames series. When all the Frames 

are taken, “Done” displays in the Status Display (24). Notice the Histogram display; it will reflect the Dark 

Frames that are being imaged. 

6. Select an exposure in the Exposure Controls (2). The Dark Frames feature is used with longer exposures, 

so your exposure time should typically be longer than 1 second. 

7. Check the Dark Sub check box (6). The Dark Frames feature is automated, so Dark Frames will 

automatically be applied to any pictures you now take. 

8. Remove the lens cap from your telescope or uncover your Deep Sky Imager camera. Begin taking 

pictures as previously described in “Start Taking Pictures.” (See page 12 for more information.) The Dark 

Frames feature is automated, so Dark Frames will automatically be applied to any pictures you now take. 

Note that if you are taking longer exposures, better results will be achieved with black and white (mono) 

images: Check the Mono check box (4) [not available for the Black and White model].

Make a Movie of the Rotation of Jupiter 

You should become familiar with autoguiding/auto tracking and calibration procedures as described in 

“Autoguider and Telescope Controls,” page 31. 

1. Click on the Save Process button to open the dialog box. 

2. Set the file type. Choose “jpeg” if just wish to create a movie, or select “tif” if you wish to process the frames 

in another image editing software program, such as Photoshop. 

3. In the Save Option, select “Save as a Time-Lapse Sequence.” 

4. Select “Jupiter Time Lapse” in the Time-Lapse presets. This preset is set up to watch the Red Spot travel 

across the face of Jupiter. The sequence takes about 4 hours and takes 24 images. 

5. Follow the procedures for Autoguiding or auto tracking as described in “Autoguider and Telescope Controls,” 

page 31. Draw box around Jupiter so that the telescope will track Jupiter. 

6. Click OK. 

7. Select “Planet” in the Image Process dialog. 

8. Click Auto Exp (3), so that the exposure will be corrected. You can tweak the color [color models only], 

contrast, shadow enhancement and so forth. as described earlier in this manual. 

9. Type in “Jupiter” in the Object name box. 

10. Click Start to begin the time-lapse sequence. 

37

Color Filters and the Black and White Imager 

The Black and White Deep Sky Imager model is shipped with a slide that will hold optional CCD RGB color 

filters, allowing you to tint, or tint and combine your black and white images. Meade offers one such filter set, the 

Meade CCD RGB Filter set, which includes a red, green, blue and IR filter. 

Tip: When you are using a color filter, write down the filter name along with the object name in the object name 

box (11). This will make it easier to retrieve when you wish to process your image. If you so desire, you may 

also write down the name of the filter you are using in the Settings menu box in the filter field. Make sure you 

change the filter color name in this field when you switch filters. 

Tip: Make sure that you use a software application, such as the IP program included with Autostar Suite or 

Photoshop, which allows you to precisely register and combine your tinted images. 

The Black and White Imager is shipped with the imager, slide and nosepiece separate. 

To install the filters onto the slide: 

1: Thread one or more color filters onto the slide so that they clear the bottom edge of the slide. If a filter hangs 

below the bottom edge, it will obstruct the movement of the slide. Thread the filters tightly into place. 

Note: It maybe necessary to focus each filter separately as you image. 

Color filter slide, top view

Color Filters and the Black and White Imager 2 

2. Thread the nosepiece into place and firmly tighten. 

Attach nosepiece. Push the slide into housing 

3. Gently push the slide into slide housing on the camera. Notice that you can feel each filter “click” in place as 

you move the slide across the camera. This will make it easier to tell if the filter is in place in the dark. 

Note the order that you installed the filters as it may be difficult to determine color in the dark. And be aware 

that either end of the slide can be placed into either end of the housing. 

You may now choose a filter for imaging.

Drizzle Tutorial #1 

This tutorial demonstrates the basic operation of Drizzle and how you get started. The following tutorial assumes 

that you have the imager on the telescope pointed at a Deep Sky object properly focused and that dark frames 

have been taken up to the longest desired exposure time. 

Recommended settings 

File Type -> FITS3P 

Save Options -> Save All Uncombined Images 

The above settings are highly recommended. FITS3P will save the full dynamic range of the imager and “Save 

All...” will allow you to run the images back through drizzle offline allowing you to try different settings. These 

setting are found by pressing the Save Proc... button on the imager tab. 

1. Select “Drizzle” from the “Image Process” dropdown menu. 

2. Enter a name in the Object Name box. 

3. Set Min Quality and Evaluation Count as desired. 

Press the Settings button. See the Drizzle Resolutions section of this document for a description of these 

settings. These settings are not critical if you used the recommended settings above because you will 

be able run the images back through drizzle off line. 

4. Start autotracking 

Follow the directions in the manual on page 31 and set up your Meade Telescope for autotracking/Guiding. 

Be sure the Imager pull down in the Telescope tab is set to the imager you are using for drizzle. The 

imagers are identified by name.

5. Select 2 stars 

The first star selected will be the shift star this is the position that will be shifted for subsequent images. 

This is also the star that will be used for telescope tracking. The second star is to determine the rotation 

angle from the first star. It is important to pick stars that are close to the center. Keep the selection within 

the middle third of the image, this way the telescope control will have maximum shift space. The telescope 

control will not shift the selected stars out of the image. When you run the images off line you can select 

different stars. If your telescope is polar mounted and well aligned you can use a single star, this will give 

you the maximum field of view possible. 

6. Press Start 

Envisage will create a new tab and put 

the drizzled image there. Be patient, 

depending on your Drizzle settings and 

the speed of your computer it may take 

2030 seconds after the count down for 

the first image to appear. The image 

may be bigger than your screen, in this 

case scroll bars will appear on the right 

and bottom. 

7. Telescope Tracking 

If you select the live image you will see 

your selected stars and a yellow circle 

with a cross. This is the target position. 

If your star was on the yellow cross 

when Start was pressed then the 

yellow cross will be in the upper right 

corner. 

More.... 

Drizzle Tutorials 2 

41

Once the star reaches the first target position the yellow cross will move to the lower right corner. The 

target position will move to the next position each time the selected star reaches it. The next position is the 

lower left corner and the last position is the upper left corner. Once the star reaches the last position 

imaging will stop. But the telescope will continue to track on the last position. During imaging you can 

change the target position by pressing the “Set Target” button and then clicking on the desired target 

position on the live image. 

8. Final Stretch 

Once the image is complete you can touch up the histogram stretch and shadow enhance settings and then 

save the final result by selecting File->Save from the menu. 

Drizzle Tutorial #2 

This tutorial demonstrates how to use Drizzle after you have already captured images and are working off-line. 

Offline Processing 

A new feature is the ability to run your captured images back through the Drizzle process. Bring up the 

program without the imager plugged in (to lighten the load of the processing power of your computer). You will 

then see the “Image Files” tab on the top. 

1. Add images 


Press the Add button in the Image Files tab on the top. The familiar Open dialog will appear. Navigate to 

the directory where the images are. Select the first image of the sequence and then scroll to the last image. 

Hold the shift key down and click on the last image. All the file names from the first to the last should be 

selected. Now press Open. After a few seconds the files should appear in the “file name” list box. 

42

2. Select images 

Select the first image in the list and after a few seconds it should appear in the live display. You can use the 

arrow keys and go up an down the list and the image will appear. Inspect each image and click on the 

Remove button to take the bad images out of the list. This will not delete the image from your hard drive. 

3. File Type: [what ever you want your final image type to be] 

This setting is up to you. The FITS file types will save the full dynamic range but the others formats may be 

more user friendly. 

4. Save Options: Normal 

This is the only setting that is valid, the other settings are ignored. 

5. Select “Drizzle” from the “Image Process” dropdown menu. 

6. Enter a name in the Object Name box. 

7. Set Min Quality and Evaluation Count to 0 and 1 respectively. 

Select these settings so that every image will be used in the final composite image. This is acceptable 

because you have eliminated all the bad images in a prior step. 

8. Press the Settings button. 

See the Drizzle Resolutions section and the sections following it for a description of these settings. These 

settings can be experimented with each time you re-run the process. 

9. Select 2 stars. 

More... 


43

Click on the first file and then select the tracking stars. They don’t have to be the same ones selected when 

the images were taken. After the selection you can use the arrow down key to check the tracking of 

the 2 stars. 

10. Press Start 


Envisage will create a new tab and put the drizzled image there. Be patient, depending on your Drizzle 

settings and the speed of your computer it may take 20 to 30 seconds for the first image to appear. The 

image may be bigger than your screen: If so, scroll bars will appear on the right and bottom. The 

current file name is displayed in the status box below the drizzle settings. The system will stop when all the 

files have been processed. 

44

11. Final Stretch. 

Once the image is complete, you can touch up the histogram stretch, shadow enhance settings and then 

save the final result by selecting File->Save from the menu. The file will always be saved to your default 

image directory. If you want to save in a different format then press the Save Proc... button and set the file 

type then select File->Save from the menu. 

12. Stretch any file. 


By selecting File->Open you can load any image file and perform a histogram stretch and shadow 

enhance(gamma) and then save the file in the currently selected file type by selecting File->Save. The file 

is always saved in the default image directory which is C:\Meade Images by default. 

45

Description of Drizzle 

Developed by NASA for the Hubble Space Telescope, Drizzle has features that dramatically increase the 

resolution and field of view of the Deep Sky Imager Pro's CCD chip. When the object being imaged would 

normally need a bigger chip camera, the astrophotographer can enable the Drizzle feature, which produces an 

effective 4.9 mega pixel camera from the Deep Sky Imager Pro's 640x480 CCD chip with Meade AutoStar 

controlled telescopes. 

It may seem that we are exaggerating, so here are the numbers: If a user selects Drizzle and inputs the value 

of 2 in the Drizzle 'Extended View' setting (effectively making a 2x2 mosaic), and a value of 2 in the ‘Drizzle 

Resolution’ (which takes multiple undersampled dithered shots of the object and reconstructs the image at 

higher resolution), they will end up with a picture that is 2560 pixels by 1920 pixels or 4,915,200 pixels. The 

uncompressed RAM file (in FITS format) will be approximately 10 megabytes. Drizzle is not simply enlarging the 

image as in interpolation. We move the telescope which in turn moves the image across the CCD sensor to 

perform seamless precision mosaics. 

On the next page is a screen shot of Deep Sky Imager Pro’s image capture software called “AutoStar Envisage” 

with the Drizzle Settings dialog box opened: 

46

Description of Drizzle 2 

In the Drizzle Settings dialog box you have three options, “Drizzle Resolution,” “Extended View,” and “Pixel 

Fraction.” Here is what happens as you change each setting: 

47

Drizzle Resolution 


By increasing the Drizzle Resolution number (maximum value 2), the image resolution is higher creating bigger 

image scale. It looks like the image is simply enlarged, but in fact by taking multiple undersampled dithered 

shots of the object it reconstructs the image at higher resolution. Notice the Drizzle Size increase from 

640x480 to 1248x936, and the final image size being 1248x936. To accomplish this increase in resolution, we 

move the AutoStar controlled telescope a small amount and take an image, again and again reading out 

fractions of each pixel and then reconstructing the image. 

48

Extended View 


Extended view increases the value to a maximum of 2 (effectively making a 2x2 mosaic). We move the 

telescope in small precision movements, pause to take an image, and then repeat the action to make a 

seamless mosaic. This increases the true field of view of the image. Notice the outer frame has increased the 

effective field coverage and the file size has changed from 640, 480 to 1280, 960. 

49

Pixel Fractions 


By adjusting the Pixel Fraction size to a value smaller than 1 (minimum setting is .20), the size of the pixel 

fraction that is downloaded from each pixel is set as the exposure is made. Using a smaller pixel fraction will 

increase the image resolution. While the final image size does not change with finer settings, the final image will 

be sharper. See the diagram with the smaller blue pixel fraction within each single pixel outlined in red in the 

following illustration: 

50


51

Field De-Rotation 


Instead of just tracking and stacking images by following the movements of one star, the Envisage Software 

with Drizzle will track and stack images locked on two stars, and can correct for image rotation that occurs if the 

telescope is tracking in the Altazimuth configuration, or in a roughly polar aligned telescope. Using this feature, 

you can do a quick alignment of your Meade telescope in Altaz, turn on the Envisage, select Drizzle, and draw a 

box around each of two stars in the field. The resulting image will not show rotational star trails. 

52

Multiple Cameras: The latest software release now supports guiding and imaging with multiple cameras: You 

can connect up to 5 and use any combination of DSI, DSI Pro, DSI II, DSI Pro II or LPI. But you must use a 

USB 2.0 interface and, if necessary, a powered hub. Make sure you have enough power in your ports to run all 

your cameras. 

Drizzle: The Drizzle function has been sped up for all models. 

Color Algorithm has been improved on color imagers. 

Zoom: If you check the zoom percentage box, you can zoom into the center of the image. If you draw a 

selection a box around a part of the image, you will zoom into that part of the image. Select a zoom percentage 

from 100% to 500%. 

The zoom check box and zoom percentage box are displayed on the tab directly above each live image screen. 

Change Stretch on Completed Images. When an image is completed you can now alter the histogram stretch 

values and save them in the final image. Just pull down the file->save menu and the image will be saved in the 

current file time. You can also change the file type in Save Proc... and then save again in the new type. 

Image Files imager type. You can now rerun images through Drizzle or shift and combine by using the Image 

Files tab. Use the Add button and browse to the files you want to use and select them in the order you want. 

Then click on the first file in the list and it will appear in the corresponding Image File tab like a live image from 

a camera. Draw a box around one or two stars if you want de-rotation and press the start button. The image will 

start building and automatically stop when all the file images have been processed. It is recommended that the 

file type FITS3P be used for the image files because you can process with the full 16 bits from the DSI.

New Features in this Release 

53

Additional Features 

Imager Naming. The new software will prompt you to name your Deep Sky Imager the first time you run 

Envisage with the imager plugged in. Keep the name short and descriptive. This name will stay with that imager 

even on a different computer. The name is used to identify the imager when using multiple imagers. It is also 

used for dark frames. If you have more than one imager it is important to give a unique name to each imager. 

You can change the name in the “Cntrl” dialog when using the Pro or the Color dialog when using the original 

Deep Sky Imager. 

Imager Tabs. There is now an imager tab for each imager connected to the computer. The tab name is the 

same as the imager name and when it is selected the corresponding live tab with the same name will be 

selected automatically. When a live tab is selected then the corresponding imager tab will be selected also. 

There is an extra imager tab called “Image Files” this is a virtual imager that can be loaded with files and then 

those images can be sent through the Drizzle process as though they came from the imager. This way you can 

rerun the Drizzle process with new settings for different results.

DSI II Features 

The following features are only available with DSI II models. Otherwise, the DSI II color model functions the 

same as the DSI, and the DSI Pro II functions the same as the DSI Pro. 

Resolution: 748 x 577 pixels. The DSI II models have almost twice the resolutions as the other models. 

CCD Temperature (41): Reads the temperature at the camera when you take dark frames. These are saved in 

the dark frames directory. The saved file name will include the length of the exposure and the temperature. 

When you click on dark frame subtract, a dark frame from this directory will be selected that is within the 5° of 

the current temperature and within 1.5 to 3 seconds of your exposure length. If you do not have a dark frame 

that matches these requirements, you will be requested to take a dark frame at the current temperature and 

selected exposure rate. 

The temperature sensor accuracy is ± 2°. Temperature readings are made in half-degree increments. 

DSI III Features 

The following features are only available with DSI III models. 

Resolution: 1360 x 1029 

CCD Temp: Same as DS II (see above) 

Color version is RGB Bayer Pattern for better color reproduction. 

Progressive Scan readout for better lunar and planetary images. 

2/3 inch sensor for a much wider field of view. 

2x2 binning.

Finally, Some Important Tips 

The following are some tips we have discovered that are very useful. Perform these procedures in the daytime, 

unless otherwise mentioned. 

• Make sure you connect to the correct ports on your computer. Use a USB 2.0 interface. 

• After you install the software, see if the camera is working. You should see lighting shifts on the live screen 

as you move it about. The camera does not have to be focused or inserted into the telescope to try this out. 

• Focus your telescope with an 25mm eyepiece in place before inserting the camera into the telescope. Once 

you focus, you can make the camera parfocal as described on page 17, or can just try to focus the camera 

with the focuser. But focus using the eyepiece first. 

• The field of view of a 25mm eyepiece is about 3 time the field of view of the camera. 

• The driver has to be installed twice. This is normal for Windows. You will hear the installation tones 

twice. Do not try to delete one of the drivers. 

• You will need to take dark frames (do this at night) to image with any of the the Deep Sky Imagers. If you 

have never taken dark frames before, or do not know what dark frames are, read up on dark frames, pages 

34 to 36.
