COMMENTS
I will not try this object with the Canon camera again.
From the beginning after registration and stacking,
I felt there was not much I'd be able to do with this image,
and although I think I went a bit to hard with the red tones and lowering them
would be a 5 minutes task, I'm going to let it stay. But beware Crescent Nebula.
One day I'll be back (just not with a one-shot color DSLR!!)
