Came out tonight to observe a maximum of EY UMa. Weather was excellent, temperature 15F, focus 2799, FWHM 6 pixels. In addition to EY UMa I took some pictures towards the beginning of the evening on the Andromeda galaxy. Arrived around 8:30PM, left at 3:30AM.

Conditions were reasonably clear (scattered clouds early in the evening while shooting calibration images), with very, very dim aurorae visible at the beginning (around 8PM local). Temperature was about 15F, focus set to 2799, seeing 4.5-5.5 pixels.
Shot darks first, then EY UMa for a few hours to catch a maximum, then planned to observe a transit of HAT-P-20….then noticed it is a known double and thought better of it (did not want to try to model that light curve). Observed a transit of HAT-P-54 instead.
Shot flats at the end of the night, around 5AM, R filter only (all observations were in R).
No equipment problems
