The Double Cluster and Stock 2
Double Cluster and Stock 2 (Borg 77m EOS Ra).jpg
The bright Double Cluster, at bottom, aka NGC 869 and NGC 884, below the large and scattered open star cluster, Stock 2, aka the Muscle Man Cluster, with a chain of stars between them. Stcok 2 is over the border in Cassiopeia. These are obvious in binoculars but less so in a long exposure photo. High haze this night added the natural star glows.
The field simulates the field of view of higher-power binoculars.
This is a stack of 7 x 8-minute exposures at ISO 800 with the Canon EOS Ra through the Borg 77mm f/4 astrograph, guided with the Lacerta MGEN-3 stand-alone autoguider and dithered, so no LENR or darks were employed. This was on the Mach1 mount. Star spikes added with Astronomy Tools Actions.
