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.
