Messier 101 – The Pinwheel Galaxy

Collimated the 8″ Celestron SCT last night in between clouds rolling by. What was supposed to be just a night of work on gear & tech turned into a mini imaging session with good results.

M101, the Pinwheel Galaxy, is a favourite of galaxy season. Hanging around the Big Dipper, this face on spiral galaxy is bright and easy to capture… one that I love to revisit every year to see progression on my skills!
