NGC 3521 Bubble Galaxy
This is my first time imaging NGC 3521 Bubble galaxy which was just high enough at the moment to capture about 1.5 hrs before trees obstruct my view towards the north west
I wish I could have snagged another hour or two but it’s location restricted more data capture
Captured at my weekender ( Bortle 3 ) south coast NSW on Saturday night

Canon 600D with Baader coma corrector

PHD2 guiding at 1.20 to 1.40 arc sec error ( guiding was struggling with the conditions , increased Min Mo to 0.30 to smooth out guiding )
Goto and tracking EQMOD, StellariumScope and Stellarium
Frame , focus and capture BYEOS
Stacked in DSS
Processed in Startools V1.5 linear data set
