Description

This is one of the targets I have been attempting every year since I started AP (3 times in row now).

I was hoping for one of those deep images but I have had major focusing issues in OIII channel. Somehow my filter offsets are getting messed up and I got sharp Ha subs but out of focus OIII subs.

I had to resort to a bunch of PI pixel math to get the nebula details from OIII while not pulling in the stars and I am reasonably happy with it (PI is seriously awesome).

Version C: Pushed contrast and saturation to bring out the soapbubble more.. but now the crescent lost the delicate look it had before.. I think I still prefer Version B.. time to preprocess!

Description: Reprocessed the files again. I think I need to redo OIII. It is much softer compared to Ha.
