Description

The global full field with these 2 galaxies NGC4656 and NGC4631 the Hockey Stick and the Whale Galaxies.

After a fisrt pass with LRGB subs , I decided to add Halpha (6 hours) to get all the small clusters and nebulas and it worked fine for both galaxies !

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
