Description

A bit over 35 hours of imaging so far for this target (31 of which survived culling); details in the sessions. Imaged from my third-floor "rooftop" deck in coastal Orange County, California (I'm less than 300 meters from the ocean) in Bortle 6+ skies. North is much brighter than south through west (over the ocean), and this target is over the bright stuff. I managed to snag the supernova last year despite four months of clouds, but didn't get remotely enough data for a color image back then.
