Description

My second take on M33. I was actually pretty happy with my first take, but comparing the two side by side reveals how much of the outer arms was completely missing in the first shot. I think I've also improved my post-processing skills as well. That said, I ended up with some strange artifacts around the stars that I may try to fix in a subsequent revision.

50x300" lights - Which is so much easier to process than the 246x10" stack

30/10/30 bias/dark/flats

I have a cooled mono camera on the way, so take 3 will be either LRGB or maybe narrowband.
