Description

I really enjoyed working on this beautiful galaxy :-)

After a first pass with LRGB subs , I decided to add Halpha (6 hours) to get all the small clusters and nebulas that shine along its length, this also enhanced its details nicely !

I hope you like it , like I do !

3 nights were necessary to get the subs: 31/01 of march and 04/05, and 12/13 of april

Red 40 subs@180s -20°C gain zero

Blue 30 subs@180s -20°C gain zero

Green 29 subs@180s -20°C gain zero

Light 59subs@180s -20°C, gain zero

Halpha 61subs@180s -20°C, gain 139
