Description

I could not resist to have a try at this very nice group of 4 galaxies about 100 million light-years distant toward the constellation Leo.

For the Light , I selected around half of the best Fwhm subs and combined them with all the subs to get sharper details and smaller stars
4 nights were necessary to get the subs: 09/10, 26, 27 and 30 of mars

Red 36 subs@180s -20°C gain zero
Blue 34 subs@180s -20°C gain zero
Green 35 subs@180s -20°C gain zero

Light 64 subs@180s -20°C, gain zero
