Excellent catch Doc but then I would not have expected you to settle for anything less! I am glad you are feeling well enough to spend some time in the observatory, if possible could you send a little clear sky me way.....please!

I'll have to ditto Dave's comment.

Can't beat simplicity, a little over 2 minutes and no post processing, that's great. 

Panstarrs has been a star photographically, with all of the many photos I've seen posted on the net.
