I was able to visit with my old advisor at Steward Observatory (University of Arizona) and go up to the MMT Observatory for a couple of nights. Conditions were amazing compared to my mag 4.5 backyard in central NC! There was a 40 mph gusting wind so my barn door had a tough time tracking without streaking stars but this particular run of shots came out well.
