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.

Works well
Worked well as expected. I have taken several images now with this filter and an Ha OIII. The resulting SHO palette is fantastic.

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.

Ha and Oii 7mm worked very well despite Bortle 6-7 sky and full moon.
Minor defects in the filter surface were negligible when images processed with flats. Good packaging. I used it with my askar 103 telescope and 1x field flattener, ZWO ASI2600MC Duo, and the Sky-Watcher EQ6-R mount. Images attached were processed using several pieces of software but no AI generation. It is important to use an astrophotography camera or camera adapted for astrophotography to capture the Ha.

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.

It is an awesome yes comparable output with respect to Optolong
I have been doing astro for a few years and have been using Optolong for long time, first time I tried to use a brand that I was looking towards and I am surprised with the outcome! This really pulled me out and I was like, wait, what? I paid over $300 for Optolong and this one was not that much and definitely gave results! to explain it, I took shot of NGC-7000 aka North American Nebula and each filter was 35 frames and after just stacking them in the PixInsight, I didn't see a major difference between the two output! well build!! I have two images, one show comparison of the SVbony with Optolong and another one is post processed image of the SVBony filter output!

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

Seems to work nicely with Dwarf3 smart telescope
It's a filter for a telescope, not really much else to say. Bought to try with my Dwarf3. It works nicely and am pleased with the results.

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.
