My first real attempt at capturing M31.

I have all sorts of excuses. Unguided. Low integration time. Still climbing the steep learning curve of PixInsight. DSLR. Also, I'm not sure my coma corrector was assembled properly. Other owners of my telescope report that the MPCC-MkIII worked perfectly in their setups. But, it doesn't seem to work perfectly in mine. Since taking this image, I've fine-tuned my collimation, and checked the backfocus, and all seems to be fine. I think one of the elements in the corrector was the wrong way around. I've flipped it, and will see my next time out if that does the trick.
