SVBONY SV220 Telescope Filter, 7nm Dual-Band Nebula, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Reduce Light Pollution for Astrophotography (1.25 inches)

Compared to Optolong SvBony is less expensive and I really cannot see any light difference or distortion

An excellent nebula filter for urban astronomers. Overcomes both local (streetlights) and general light plllution. Used a Sybony SV555 and ZWO ASI 585MC Pro with good results.Recommended.

I gave it five stars because I didn't want to hurt its rating with this non-review. I'm only writing this for those that are thinking about using it with the Celestron Origin. It would probably take great photos, but the Origin will not come to focus using automatic focus and this filter. If you focus manually, it should work fine, but I'm not interested in needing to do that if conditions change or if I'm doing some scheduled imaging.

Excellent filter, and at a reasonable price

nice filter nice price

Es el mejor filtro que he usado para astro fotografía profunda. Se puede ver los colores de las nebulosas mejor que el UHC o el UV/IR. Estoy sorprendido de la calidad con que se puede ver las imágenes.

This filter works amazing for adding contrast to emissions nebulae, especially for OSC and DSLR cameras. It is a narrow band filter, so it will cut out a lot of light by design. I've found that doubling either time or ISO gets you pretty close for exposure. If you're wanting to start imaging emission nebulae, I highly recommend this filter. I've attached pictures of the Orion and Rosette nebulae that I took through this filter. Imaging was done in class 5 conditions with a stock Canon R100 and a Skywatcher Quattro 150P

This filter blew my mind at this price point. It produces a very quality image. You will definitely not be disappointed with this purchase.
