Constellation of Cancer the Crab, taken April 3, 2011 under hazy skies from home, with Canon 5D MkII and 50mm Sigma lens for stack of 5 x 3 minute exposures at ISO 800 and f/3.5 plus stack of 2 x 3 minute with Kenko Softon filter. Head of Hydra is at bottom.
Cancer under slightly hazy skies, Feb 2, 2011, with Canon 5D MkII and 50mm Sigma lens at f/3.2 for stack of 3 x 4 minutes + one 4-minute shot with Kenko Softon filter for star glows. Procyon at lower right.
A framing of the northern spring constellation of Cancer the Crab, between the constellations of Leo (at left with the bright star Regulus) and part of Gemini (at upper right with Castor and Pollux) and Canis Minor (at lower right woth Procyon). Cancer is marked by the large binocular star cluster, Messier 44, the Beehive, at centre here. The head of Hydra is at bottom centre. Between the two is the small star cluster M67, just resolved here. This is a stack of 11 x 2-minute exposures with the Canon RF28-70mm lens at 34mm and f/3.5 and on the filter-modified (by AstroGear) Canon R 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 constellation patterns and star colours. Taken from home March 16, 2023.
