Cancer Clusters (60mm Ra).jpg
A framing of most of the northern spring constellation of Cancer the Crab. Cancer is marked by the large binocular star cluster, Messier 44, the Beehive, at centre here. At bottom is the small star cluster M67, just resolved here. Pollux is at upper right, in Gemini. The brightest star at top centre is the double star Iota Cancri. Immediately to the left is a double star, resolved here, with the top star in the pair being 55 Cancri, home to a notable extra-solar planetary system.
This is a stack of 14 x 2-minute exposures with the Canon RF28-70mm lens at 61mm and f/2.8 and on the filter-modified Canon Ra camera at ISO 800, on the Star Adventurer tracker. An additional single 2-minute exposure through a Kase/Alyn Wallace StarGlow filter and layered and blended in Photoshop added the photogenic star glows, to accentutate the star colours. Taken from home March 17, 2023.
