Description

M 109, a Barred Spiral Galaxy in Ursa Major about 83 Mly away. This one drove me crazy in processing, in fact, I fear all of my galaxies from last night are going to be tough because I can't get my darks to apply so more and more processing to keep image clear. C8@f3.3, 30x30sec exposures wtih Meade DSI II OSC, Nebulosity, with some work in StarTools and PS.
