Description

I spent the last two nights collecting data for this target. Of the 10 hours I collected, I had to throw away 6 due to high cloud. Fortunately I already had 10 hours of H-alpha.
So this is just over 14 hours of integration time, 1 h B and G, 2 hrs R, and 10 hrs H-alpha.
I would really need another few hours with the Blue filter, in order to get better definition in the arms of this galaxy.
The tidal tails (arcs) are just showing in the colour masters, but are still far too weak to show off here.
