Quick test of my new f/6.3 focal reducer. It's not entirely evident in this image, but there's a lot of vignetting when using it... which was helped by my flat frames—just not enough. The reason has something to do with my 1.25" T-Adapter. If I get a 2" one I should be fine... but then I won't be able to use my light pollution filter. I've done tons of research, but cannot find a 2" T-Adapter that accepts filters. And even if I did find one, I'd need to also probably find a 2" visual back. Sometimes this stuff can get rather confusing....
