    About the Optolong L-Pro Light Pollution Filter

    This L-Pro (L-Professional) filter is designed to improve the visibility of various deep-sky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lights including mercury vapor lamps, both high and low-pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

    Together with the highly transparent in main nebula emission lines at O-iii(496 nm and 500 nm), H-beta (486 nm), N-ii(654 nm and 658 nm), H-alpha(656 nm), as well as S-ii(672 nm), the filter is suitable for enhancing the contrast and details for both visual and photographic purposes from sub-rural areas with heavy light pollution.

    Unlike other light pollution filters (UHC and CLS,) L-Pro is a multi-bandpass filter offering excellent color balance by maximizing the transmission band. The balanced transmission allows astrophotos to be taken with minimal color cast to broadband emission objects such as galaxies, reflection nebulae, and globular star clusters. L-Pro is the best choice for light pollution suppression.

    Main Use and Performance

    Suitable for visual observation and astrophotography.

    The L-Pro filter has a very low transmission reduction rate against continuous spectrum space objects and thus is quite effective in suppressing light pollution sources when shooting galaxies, reflection nebulae, and globular star clusters. The same holds true for visual star observations.

    L-Pro filters alone can suppress infrared wavelengths, and thus can be used at ease for “L” image shooting with CCD cameras. Light pollution filters do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

    MANUFACTURER'S WARNING: The filters of Optolong are not designed for sun observation. DO NOT LOOK AT THE SUN WITH OPTOLONG FILTER

    Very hard to install and to remove

    I already own the 2" L-pro filter and it's very helpful in mitigating light pollution. However, this version for the sony camera was a complete miss. It's so hard to install and to remove from the camera body. I've even accidentally touched the cmos chip while putting it in. Hopefully, Optolong sees this and finds a better solution.

    Does not fit in my Sony a7II

    Very frustrating, I had height hope for this filter.
