Description

Followed Adam Block's advice to keep all subs and allow PixInsight to give low weights to the bad ones while still maximizing SNR.  Seems to have worked; some subs had elliptical stars but the stars in this image look round to my eye.

I pushed the stretch a bit in order to bring out the wisps of M81's "halo".  I was surprised to capture any of it through a telescope of this size.
