Description

My first image with my new QHY 268M camera. The extra sensitivity of this cam really shone here - in only 7.5 hours, I was able to produce a noise-minimal image clearly showcasing M101's faint outer spiral arms. The added real estate of the APS-C sensor also allowed me to capture the many other members of the M101 group, including a set of galaxies in the upper right, and the interesting dwarf on the left.
