I bought this to see if it would help bring out some color and detail for my astrophotography. I have little light pollution in my area but it this thing really does what it's supposed to. I did some test shots with a colorchecker passport in regular daylight and the difference is definitely noticeable. There's a very clear boost in color and slight boost in contrast, what I mean is that they appear more clearly and saturated. It's magic! I might even start using this for some regular photography too! I have to use step-down adapters to fit these onto my lenses as I am not using it with a telescope (67mm, 58mm, 52mm). I just wish they made these in sizes native to DSLR/Mirrorless lenses! Highly recommend! Also if you are someone purchasing for a DSLR/Mirrorless camera, Get the 2 version of course, and you will need step-down/step-up adapters to 48mm. Even though 2 is not 48mm, that is the threads for this baader filter. I recommend the sensei filter adapters, cheap and very well made. In order to adapt some lens sizes down to 48mm, you might have to buy a couple adapters and stack them. I had to do this for my larger 67mm lenses. There will of course be vignetting when doing this, but its no big deal to me. 5

The CMOS air filter provides clean air for the Nitecore BlowerBaby, which gives additional assurance while cleaning camera sensors and lenses. 5

What can I say about an air filter. It appears to be quality made, 5

Very nice. Could use one more thread though. Seems a little short on threading when trying to attach and remove while making lens changes in the dark. Makes me a little nervous sometimes that I will drop it during removal from the lens. Good quality though and I like having it around. 5

Excellent filter 5

They work quite well; no halos or any undesirable behavior which I could notice as of now. They did require an increase in exposure time, but that's expected. 5

I have filters for both astrophotography and photometry. Getting a second carousel for my filter wheel was a good economic solution. It would be great if this came with a protective case. 5

One of the best items I've purchased for my 140mm telescope. The reduction in sky glow and the contrast improvement add to those Oh, Wow! moments of star gazing. 5
