Here is a wide field image of M81 and M82 and a few other friends in the group. I was at my favorite dark site, but the wind was howling - my tent blew down. So what do you do when it is windy? - Shoot wide fields! Image and exposure / processing details are here:

Really nice wide field. Great way to take advantage of the conditions. And you have to wonder, just how many of those "stars" are really more distant "friends".
