SVBONY Telescope Filter UHC Filter Ultra High Contrast Filter EOS-C Clip-on for CCD Cameras & DSLR Reduce Light Pollution

This is my second attempt at photographing the Orion Nebula (M42, "The Great Nebula In Orion"), and only the second deep sky photo I've ever taken. I'm happy with this. It is the result of 88 images stacked in Deep Sky Stacker, ranging from 1 second to 35 second exposures, ISO 3200. I used a few Dark Frames and Bias Frames, but no Flats, so I probably could have done better, and I would recommend ISO 1600 maximum. I used a Celestron Nexstar 6se on an Alt-Azimuth mount, 2-star alignment using Sirius and Polaris, f6.3 (Celestron Focal Reducer), approx. 1053 mm focal length, Canon T3i with SvBony UHC (light pollution) clip-in C-frame filter. I used a Bahtinov mask to confirm focus on Sirius prior to using "Bulb mode" on the camera with a cable release made by Apurture. Yes, I said Alt-az mount, no wedge, not polar aligned. With a wedge I could do 2 minute subs instead of the 30-second maximum I was boxed-in with. Seeing conditions were Bortle Class 6 with a street light directly in front of me, so think more like Bortle 7. Final image adjusted for levels, color correction, and contrast in Photoshop CS 2020. I'm blown away. Without this filter all I got was a yellow haze and a grainy image. I'm probably going to buy their CLS filter as well, even though the bandwidths are very similar. I also bought their 1.25 inch eyepiece UHC filter for visual astronomy. I'm sold on this company. Highly recommended.

I try to keep my astrophotography habit within a budget. It is not always easy. This little filter, however, is fantastic. You can see in the chart on this page how this filter lets specific bands pass, while blocking other light, mainly light pollution. I live in a bortle 5 in small town NC. However, both of my neighbors have security lights on all night (uggh). This filter does the job it says, blocking pollution that makes photos look overexposed, while letting in reds and blues. It fits my Canon t6 perfectly (after pulling out the bottom prongs a little), and stays snug while it sits at prime objective attached via a T-Ring adapter on my achromat. Note that this filter will not allow you to use any lens that needs to attach to your camera that uses autofocus, etc. as it blocks access to the electronic pins. However, if you are using the camera at prime focus on the telescope directly, it is perfect. Pictures in RAW tend to have a tint to them, but this can be adjusted out with a color balance in post processing.

ease of use, Hobt pops straight into my camera and the performance was pretty great in my opinion and it’s not that expensive

I bought this to help reduce night glow in our Bortle 7 city. It works well for cutting light pollution. High contrast images without compromising image quality. And is comparable to the supposed top-tier brands. Great SVBony quality for less! Super easy to use, clips directly in to camera body then attach your lens. Simple. Also helps protect camera internals a bit from dust while changing lenses.

I was fairly new to astrophotography when I first got this filter and assumed it was as good as the reviews said it was. I never had great results with it and only recently did I notice that it was causing a color gradient on my images. I'm assuming it was this way when I got it, and have no idea how it would've otherwise been damaged. It's basically useless to me now.

Just what I needed for my Astro modified Canon t5i.

I wasted $70. I got this lens because it said it was compatible with the EOS Rebel T3. It fits fine inside the camera body. But when it comes to putting on my lens...it doesn't work... However they cut this this filter it's way too thick as one review stated. DO NOT BUY!

Lástima ni lo pude acoplar a mi cámara Canon 5D Mark III

This filter is excellent for the price. The picture that I've attached was taken under bortle class 4 skies with an unmodified t5i. The filter helped me gather detail in the very faint nebulae details, and it did a decent job.
