Description

A slightly cropped widefield view of two Messiers objects.

M97 and M108 came out reasonably well, however the stars certainly have issues. The flattener - reducer has been recently rotated and I 'think' I now suffer from some chromatic aberration - which can be seen by closely inspecting the corners. The spacers are unchanged so back focus should not be a factor. The subs also show a quite a number of stars when unstretched so I may be over-exposing as well. 

In any case - still worth a share.
