🌠 Capture the cosmos like a pro—no dark sky required!
The SVBONY SV220 2" 7nm Dual-Band Nebula Filter is engineered for deep-sky astrophotography, selectively transmitting key nebula emission lines (H-Alpha and OIII) while blocking light pollution and moon glow. With over 94% light transmission and a rugged waterproof anodized aluminum frame, it enhances image contrast and detail for color CMOS, CCD, and digital cameras, making it the go-to filter for urban astronomers and astrophotographers seeking crisp, vibrant nebula captures.

Great nebula filter
Great filter at a good price! Good results with my stock/unmodified canon DSLR. Still able to focus on bright stars using a bahtinov mask. Suppresses over exposed and bloated stars, minimizing the need for star reduction. Blocks almost all moon-glow, allowing more emission nebulae to be imaged during the full moon. Of course it's not suitable for reflection nebula and galaxies, since it only passes Ha and OIII.

Very good dual band filter
Outstanding filter. Made a huge difference in my imaging. Because of 2" size, no notice of vignetting with ASI533MC Pro.

Glad I bought it
My photos attached speak for themselves. This filter is amazing and much cheaper than competitors.

Worth the $$
Works well. I use this for wide field nebula imaging. It preforms on par with filters costing 1/3 more.

Works for me!
I wanted something for my smart scope that would help reduce noise and still capture emission nebulae. This works perfectly for that. Has drastically improved the quality of my images in post processing.

SVBONY SV220 vs Optolong L-Enhance
I am very happy with this purchase. The picture on the left is 3.5 hours worth of data shot with the SVBONY 220 7nm 2" filter with a ZWO 533MC on a Redcat 51. The picture on the right is 10.5 hours of data with the same rig except was shot with the Optolong L-enhance. Both picture were processed excatly the same. Cropped, Graxpert/Background extraction/denoise. Loaded into Siril and autostretched and then saved.

Solid Filter for Ha/OIII in 1 frame
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

Looks professionally made
Fits 2 inch eyepieces. Made to reduce light pollution. Cannot comment on efficiency as have not used it yet due to weather conditions, sorry.

Bueno, pero no Perfecto.
Por el precio, es un buen filtro, especialmente para principiantes o quienes no buscan fotografías 100% perfectas. Produce halos, especialmente en las estrellas más brillantes. Pero es un buen producto para comenzar en el aprendizaje y uso de fotografía de doble banda estrecha.
