Description

Messier 101 The Pinwheel Galaxy

Despite being a large and distinct Messier object, the galaxy proved somewhat difficult to capture under suburban skies. The low surface brightness seemed not much higher than local skyglow. Numerous 60 sec subs (my usual exposure length for galaxies) were scrapped and recaptured at 180 sec to gain enough SNR.

Would like to retry this object again next season and gather more total data to process.
