Description

Here's my attempt on M17. Had a lot of elongated stars due to some friction in the mount or cable drag, also even with the belt mod my guiding at these low altitudes was quite bad, a lot of tweaking still required and only a few subs. Quite a lot room for improvement ;)

Inspired by the small conversation with Ron Adams and also looking at Masahiro Takashi's version of M17 I did a full rework. I did the Bicolor Combination in Photoshop instead this time so I could real time preview when I played with the curves of each channel. Finally some OIII Blue .... What a saga :)

My images need to stay longer in the staging area ... when I have a bit of free time I look at them again and always find something I want to change ;D
