Description

A rather rarely seen spiral galaxy in the constellation Leo and still belonging to the Virgo Supercluster. In image B I show another version, which has a larger field of view. The big star above creates a very own image composition, I guess. Hope you enjoy :-)

This is by the way my last image for which I used my Astrel 16200B CCD camera. New one already arrived :-)

Revision: C

Description I have increased the intensity of the stars a little more. It should sparkle a bit more in the background! :-)
