Opticstar DS-336C XL Help Please

[duncan.p]

I have recently purchased an Opticstar 336 and plan to use it with the bundled software: Nebulosity V2. Does anybody have any experience of this setup; I plan to use it with a SolarMax 60II and a Skywatcher Evostar 100Pro.

I have a tutorial on nebulosity: Astrophotography acquisition and processing in Nebulosity

As for the camera - it has very small pixels so Evostar with 900 mm of focal length will give much to high resolution. IMHO no more than 500 mm for this "camera"

Thanks for the link to the tutorial.

Not sure I understand what you mean about too high resolution - I thought high resolution was a good thing

Each sky has a resolution limit. In Europe in common places it's very unlikely to do images at a resolution bigger than 1 arcsec/pixel, where usually 2 arcec/pixel or lesser will give better results (as the sky won't be best).

That Opticstar-crazy-cam with 3.45 x 3.45 pixels would give you 0.79 "/pixel at 900 mm - hard to use, and harder to guide. And binning on color cameras isn't also a effiecient thing. Smallest short ED refractors are the way to go with such pixels.
