Description

Version LRGB with Halpha : I reworked from the LRGB and remix the Halpha , a lot of work actually to find the right balance of everything. I hope I deliver something you like !

Another very nice and large galaxy of the seaon !

Same process as the last images : for the Light , I selected only 29 subs of the best Fwhm subs (out of 80) and combined them with all the subs to get sharper details and smaller stars

I had also improved my star and halo process

A small Galaxy to the upper right is no detected by the astrometry : UGC8313, is part of the galaxy group of M51 and M63 (wiki)

5 nights were necessary to get the subs: 23/24, 25 27/28, 29, 31 of march

Red 30 subs@180s -20°C gain zero

Blue 30 subs@180s -20°C gain zero

Green 40 subs@180s -20°C gain zero

Light 80 subs@180s -20°C, gain zero

Halpha 97subs@300s -20°C, gain 139
