Hesitating to post yet another M42, but this is my first attempt with a CCD camera, and a big step up from my DSLR image from a few years back. Fairly limited number of 5 min subs due to clouds moving in. I managed a lot more 30 sec subs for the core. Looking closely at some of the bright stars in the full size image, I see there's a very slight misalignment of red channel.
Takashi TSA-120 with reducer, FLI Microline 8300.
