Description

Second attempt at M27 and first in 4 years. My processing has evolved to remove all heavy PhotoShop editing that was prevalent when I first started out. Only PI was used here. The result is a much more natural look. Was hoping to get more data and was not able to immediately create flats. WIll update if I get them in the next few days. That said PI does a great job of flattening image that was pretty bad straight out of the can.

Last attempt is here: https://www.astrobin.com/124097/C/
