The famous Double Cluster (NGC 869, right and NGC 884, left) in Perseus, in a wide-field shot that includes the nearby stars clusters NGC 957 to the left, and Trumpler 2 at bottom left. The large and sparse cluster Stock 2, aka the Muscle Man Cluster, is at upper right. The field is filled with yellow supergiant stars. The field of view is similar to that of binoculars. This is a stack of 20 (!) x 3-minute exposures with the SharpStar 61EDPH II refractor with its reducer/flattener at f/4.5, and the Canon Ra at ISO 800. Autoguided with the MGENIII, on the Star Adventurer GTi mount taken as part of testing the mount. A slight camera tilt from the reducer's rotator mechanism being a bit loose produces slightly soft stars on the left side of the frame. Taken from home September 25, 2022.
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.
Eta Carinae Nebula area with Lambda Centauri (Running Chicken Nebula) nebulosity. Taken from Atacama Lodge, Chile, March 18, 2010, with modified Canon 5D MkII and Canon L-Series 135mm lens at f/2.8, for stack of 5 x 3 minute exposures at ISO 800.
