M109 and Phecda in Ursa Major

A double dataset was processed for this one.  From 7th March 2011 27 subs at 10-minutes per sub, and from 13th March 36 subs at 5-minutes per sub.  The odd shaped resulting image shows the overlap wasn’t too good between the two frames.  In fact the overlap wasn’t bad – it was the frame rotation (due to poor polar alignment) between the two dates that caused all the problems.
