good for refractors downtown
very good for city deep sky view

Great buy
I’ve only had a couple of sessions worth of imaging with this filter, but the results so far are great. I’m close to downtown in a major city and to a street light and I definitely notice a difference in picture quality with this filter. It’s great for nebulae and really brings out the reds. It’s not so good for galaxies and star clusters as far as I can tell. Just starting to really dabble in filters and this one was worth the buy.

Improves nebula views
Amazing at isolating nebula for visual use. Using this in the city with bortle 9 light pollution. Able to see clear difference when looking at orion nebula or cygnus region. Really improves contrast

Amazing value.
So far it's been an amazing little filter. For the price I think it would be hard to beat. I'm working in a bortle 5 with a lot of neighborhood lights and got a beautiful quick 3 min sub of the Orion nebula. I'm looking forward to trying it out on some more difficult targets soon. Picture was taken with a zwo asi533mc pro at f5.

Better contrast for visual observation
I used the SVBONY 2-inch UHC filter for visual observation, and this is my first UHC filter.I was able to see the M94 galaxy, which I had never seen before against the bright sky background, with my 8-inch SCT. This filter makes the sky appear much darker while keeping most nebulae visible. I noticed significantly better contrast with the M17 Omega Nebula, though I feel that some fine details might have been filtered out and lost.I would not recommend it for visual observation of globular clusters like M3 and M5. The image was only slightly less sharp, and I thought I saw some reflections.The craftsmanship is excellent; the glass appears to be top quality and very clean. In my video, you can see that this filter gives an image with a slight violet tint.I can't compare it to a high-end UHC filter because I don't have one, but for its price, I think this filter is excellent. It will most definitely help you see faint deep-sky objects that you might have wondered if they were even there.
