Description

Hi all,

Messier 110, also known as NGC 205, is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy in the Local Group. It is designated peculiar due to patches of dust and young blue stars near its center. This is unusual for dwarf elliptical galaxies in general, and the reason is unclear.

I share this image taken by my friend Serge Brunier from the one meter Newton of the C2PU with the QHY 600 camera. 12 hours of luminance and 1 hour per RGB channel. 60 seconds subs.

Processing : layers L,R,G,B stacked by Serge. Assembly and processing myself.

I find the number of resolved stars amazing. It looks like a milkyway, but extragalactic ! At the bottom left, the suburb of M31.

Hope you like this one.

Please, have a look at the full resolution. What looks like noise in low resolution turns into a crazy amount of faint stars.
