This is one of my first dark sky images of a star cluster. It was done in 2012 at Kootenay Plains on the eastern slopes of the Rockies. There is a grand total of one full minute invested in this picture. It's just two frames, each 30 seconds long.

The cluster looks not too bad at full size. But if you zoom in, even just a little, you will see thay are badly malformed. Still, there are lots of stars and the cluster clearly stands out against the background star field.
