Product Description
The relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. L-eNhance provides an economical and practical solution for amateurs. It is a dual band-pass narrowband filter which has been designed for DSLR (digital SLR), color CMOS and CCD Astrophotography Cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas. Optolong believes the design of our L-eNhance filter is a technical innovation among filters. It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers images that superbly control the impact from light polluted skies. According to the characteristics of celestial body emission lines and the light pollution spectrum, Optolong specially designed and optimized dual-band L-eNhance filter in order to retain the prominent color of nebula RGB while blocking out most of light pollution. The Optolong L-eNhance filters have threads on one side - they can be used with filter wheels, filter drawers, focusers with a place to thread focal reducers internally (such as some Moonlite focusers) and camera nose pieces that fit into compression rings but the filter should not be threaded into the imaging train like an adapter ring with threads on both sides. Substrate: B270 Thickness: 1.85mm Tpeak: T>90% Blocking range: 300-1000nm Blocking depth: Light pollution line blocking >99% Surface quality: 60/40 Transmitted Wavefront RMS: λ/4 Parallelism (arcsec): 30s

Customers are mixed about the light pollution. Some mention that it blocks ambient light, light pollution, and moonlight very well while enhancing, and helps clear up the light haze. However, others say that it darkens their view through their camera and needs longer exposure times to compensate.

"...Just be aware that blue star color it's lost. Extremely dark will need longer exposure times to compensate" Read more

Okay, setting that aside, I took the filter out for a test last night, in a totally light-polluted backyard in suburban Detroit, with a full-moon also in the sky and didn't even really try to set up anything with much effort. I just wanted to see roughly if this filter was worth the price. The result was the attached image of the Orion Nebula. I've photographed it before, but that was under a dark, dark sky far up north, and no moon, and none of those came out as nice as what I took last night under all the worst conditions. I'm a bit in shock that I took this photo. I'm still a pretty beginner amateur at this, and one who has very little money and has had to cobble together some mediocre equipment and still have only had sporadic success in the field, and though I'm sure others can and do take much, much more impressive shots that this one, for me it's a beaut and it was just the first try. So, though I've only barely used this filter I'm pretty impresssed with this result. I can barely wait to take a trek up north and test it out under ideal conditions. So from me, I'd say it is worth the price and it does take things up a few notches for sure.

I’m shooting RGB with a unmodified Nikon D5300, and can still get some Ha spectrum through this. I’m quite happy with the purchase.
