Some of the celestial objects best viewed using this filter are Cocoon nebula, M42, M43, California nebula, North American Nebula, and the famous Horsehead nebula. And LPR filters aren't really all that effective. entityType: 'ensemble' These filters are therefore much more effective in cutting out light pollution but they also cut out light from more "normal" objects. To combat this issue, they designed light pollution filters. 1x filter factor. Even when I go camping and set up shop in a field away from city lights, there is growing sky glow that makes my images less clean and harder to process.

They benefit best ... DO NOT use Optolong filters to observe or photograph the Sun. Check Price on Amazon. The balanced transmission allows astro images to be taken with minimal colour cast to broadband emission objects such as galaxies, reflection nebulae and globular star clusters. Unlike narrowband filters, broadband filters work well on galaxies and star clusters as well as nebulae. Also, do they actually work? H-alpha 656nm, OIII 496nm and 500nm, SII 672nm and H-beta 486nm, Precision off-band blocking, specifically the major emission lines of artificial light pollution (i.e. I've just purchased the 2" version for my Evostar 72ED setup after using the 1.25" version fitted to an um-modified Canon 1000D on a Celestron 6SE.
