Description

Another very nice and large galaxy of the seaon !
I start the subs with Halpha because of the moon :-) , but finally I start processing the image without Ha , don't tell me why !

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
