Description

M101 composited from two different exposures gathered in two different locations. The 240 second subs were gathered on April 28, 2024 in a Bortle 6 area of Castaic, California under a 78.68% waning gibbous moon, and the 120 second subs were collected at Bortle 4 Afton, Illinois on May 11, 2024 with a 16.15% moon. I had also collected 90 second subs a week later, but the moon pollution was too great for such short exposures.
