Description

NGC 2366 is a barred irregular dwarf galaxy located in the constellation Camelopardalis. It is part of the M81 group of galaxies, and lies about 10 million light years away. The southern end of NGC 2366 has a large, luminous HII region known as Markarian 71. Inside Mrk 71 there are two super star clusters (SSC) which are named 'A' and 'B' or 'Knot A' and 'Knot B'. To the side of Mrk 71 is another dwarf galaxy NGC 2363 which is interacting with NGC 2366.
This was a dim, challenging object, with an apparent magnitude of only 11.4, but the components were spread over an area of 8.1 x 3.3 arc minutes, so it was at least large enough to attempt to capture.
