SVBONY Telescope Filter 2" CLS Broadband Filter, Reduce City Light Pollution Suitable for Deep Sky Visual Astronomical Photography

Works great, I used to to take this picture of orion nebula from my bortle 8 backyard

Bortle 9+ skies. Neighborhood: Oak Cliff. Just outside of Downtown Dallas Texas. The worst possible place to view the stars in my opinion. Equipment: Orion XT6i doing visual astronomy. We couldn't see much in all honesty, Because the sky was like looking at the stars through an empty plastic milk jug. After viewing the Orion Nebula for a few minutes, I remembered having my CLS Filter. Screwed it on and it made substantial difference! The Orion Nebula had a lot more contrast and detail. It was visibility much more enjoyable to observe. After that we looked at a few double stars and Pleiades which looked nice. Can't comment on Astrophotography, but for visual viewing, in the described sky, it made our night go from "hohum" to "Oh wow! Look at that!"

Looks good. Yet to try it out

Buen filtro de luces de ciudad (no las led) pero si con las amarillas de mercurio.

I like it it really cut out the light pollution
