Hi Petur,

These pictures are fantastic.  The detail is exquisite.  When did you 
fly there?

Do you have a pier set up in your yard or do you have to polar align 
each time? How often did you have to check the setup during the 
exposure, assuming you were using camera control? Hubble, Humason, 
Herschel, not to mention all the other lettered observers, have my 
utmost respect for their wear-with-all in cold weather observing and, 
later, guiding.

Best,
