Description

Too small for a 10'' but well , I give a try, definitly , need à 16 or 20 inches :-)

Please look at the original version which is the full field made with ZW ASI1600 and at 1000mm of focal Newton F4, the mice are soo small at 290 millions lihgt years away.

The bad weather prevents me from doing more green...

Red 20 subs@180s -20°C gain zero

Blue 19 subs@180s -20°C gain zero

Green 7 subs@180s -20°C gain zero

Light 47 subs@180s -20°C, gain zero

4 nights were necessary to get the subs: 29 of April, and 01/02, 02/03 and 06/07 of May

WIKI :

NGC 4676, or the Mice Galaxies, are two spiral galaxies in the constellation Coma Berenices. About 290 million light-years away, they began the process of colliding and merging. Their name refers to the long tails produced by tidal action—the relative difference between gravitational pulls on the near and far parts of each galaxy—known here as a galactic tide. It is a possibility that both galaxies, which are members of the Coma cluster, have experienced collision, and will continue colliding until they coalesce.

The colors of the galaxy are peculiar. In NGC 4676A a core with some dark markings is surrounded by a bluish white remnant of spiral arms. The tail is unusual, starting out blue and terminating in a more yellowish color, despite the fact that the beginning of each arm in virtually every spiral galaxy starts yellow and terminates in a bluish color. NGC 4676B has a yellowish core and two arcs; arm remnants underneath are bluish as well.
