Description

This is a part of the Leo cluster (Abell 1367) which is part of the Coma-supercluster which is part of the Coma-wall - one of the largest know structures in the Universe. The brightest galaxy here is NGC 3842 which contains a black hole more than 2000 times the mass of the milky way black hole.

I mixed in some mono frames with the ASI178MM and the SW130/650 PDS into the luminance channel. That's why there are spikes around the bright star.
