This 9.7 mag spiral in Leo is one that got away from Messier. It's brighter than some of the ones he did catch in here, and is a real treat in a good scope.
This data is two nights (6 hours used) worth of 5 minute LRGB subs, although Perth's summer has finally caught up and the temps have stayed above 30 in the dome, so the poor old QSI hasn't been able to cool itself off. Hence the noise!
