Sun 25 May, 17 pane mosaic.

So this afternoon I had a bit more time and stitched 17 panes together with Autostitch which went quite well considering I used Alt-Az mode on the mount.  Here are the various images:

Normal:

False colour normal:

I just had another peek at AR2659 and it is extremely bright through the Lunt 60. Thanks for looking.

Thanks very much for your comments.  This is the first time I have paid attention to taking a range of flats.  I tried 3 different methods:

1) Cling film at 70% histogram

2) De-focus at 70% histogram

3) De-focus at 50% histogram

I processed one of the panes via each flat master through AS!2.  There was little to pick between them but in my view the second option above gave the best result and the most even illumination.  So I used a master flat based on option 2) for all the panes.
