This image shows you tiny paralleling three galaxies in the tip of Big Bear's forefoot, about 3 degrees southwest of theta UMa. A well-proportioned face-on spiral is NGC2857, central one is NGC2856, and a galaxy in lower right hand side has a number of NGC2854. All galaxies have brightness of about 12th or 13th magnitude and sizes smaller than 2 arc minutes.
