Classic Pleiades M45

I imaged this after SH-129 was coming too low on the horizon, and with a few hours left before down and comet Giacobini. I was lucky and got 30 good lights of 5 minutes exposure.

Happy also to find the edge-on spiral UGC 2838 in the frame, a magnitude 16 galaxy of 0,8x0,1 arcminutes at a distance of 280 million lightyears.
