This broadband (50nm) UHC works well and has allowed me to view nebula (other than M42 / Orion Nebula) for the very first time from my light polluted backyard. I never thought I would be able to detect nebula from my backyard, where I do most of my visual observing using 8" and 10" F5 dobs. I'm in a red/white light pollution zone which is considered "Bortle 8" aka "can't see ****, captain". This filter hits well above its weight and is comparable to a more expensive Optolong UHC filter. Even with most of my city using LED street lights, whose light pollution is harder to filter out, this filter performed exceptionally and allowed me to detect nebulosity in Scorpius last night. The nebulosity was faint, but it was absolutely there. I didn't need to use averted vision or any other aids to detect it. With visual observing, you can't expect bright Hubble views albeit I suspect this filter would work exceptionally well for astrophotographers, who will be able to achieve great results with this filter + long exposures. The fact that I could visually detect any nebula at all that wasn't M42 in Orion makes this worth the measly $20 paid. Members of a popular astronomy forum have sent the SVbony UHC filters out to Lumicon- one of the top optics and filter labs- and it revealed that this filter is virtually identical in performance to Optolong UHC filter and may even be the same thing. The Optolong is well regarded and sells for $80; a $20 SVbony performing the same as a filter that is 4X as expensive is a great deal. The price and the performance of this makes it a must have filter if you don't have one. I'm not a fan of filters as I find the price:performance underwhelming for visual observing, but this filter hits all the right notes. I will likely buy SVbony's 2" version of this filter, I like its performance enough that I want it available for my 2" wide field EPs. I wish SVbony made an OIII; I'd buy it in a heartbeat if it performed as well as this UHC.

I am still very much a novice astronomy hobbyist and learning as I go - but this this filter has been a big help getting those nice planet images even in surburbia

I have a 4.5" (114mm) f/4 Zhumell Tabletop Dobsonian, that I've been using for several months. Last night we had clear skies, but 6" of snow cover reflecting all the Christmas lights back up into the sky--so the light pollution was substantial. However, since the moon was not out the seeing was pretty good, which made it a good time to test this little Svbony UHC filter! In relatable terms: the sky was dark enough to see the Pleiades and the Orion Nebula with the naked eye (the latter requiring judicious use of indirect peripheral vision)--but not clear enough to really make out the Milky Way. Despite the imperfect conditions, I was actually startled when I first focused on the Pleiades... Everything wasn't just shades of grey--I could see blue! I've been able to see red and yellow stars previously (you can even make out the difference with the naked eye) but the Pleiades just popped with blue! It was a memorable experience, and really quite moving. I won't forget it. The Orion Nebula was similarly stunning, the contrast was excellent and the color beautiful. ...Long story short, I spent an hour (possibly more) in the cold snow mesmerized by GOD's wonderful creation! Well Done SVBONY!

As far as images I am really surprised at how well this works. From Bortle 6-7 on the bright emission nebula in orion, it helped bring out more color and cut down the orange glow (only a single sub before the clouds came). For visual use I didn't notice much difference but to be fair when I tested it visually I was in bortle 4 to 5. I imagine it helps more, the more light polluted your skies are.

It certainly made some difference, but with all of the LED lighting there is just no filter that can help.
