The well-known Double Cluster (aka NGC 884 and NGC 869) framed at upper right to include two of its companion star clusters, NGC 957 at upper left and Trumpler 2 at lower left. Dotted through the field of young blue stars are numerous aging yellow giant stars. And the gradation in sky colour from the clearer, bluer sky with more stars at right to the dustier, yellower sky and fewer stars at left is subtle but obvious here, from interstellar dust in this part of the Milky Way. .
