Pluto is a challenge from 55 degrees North. It currently only rises 16 degrees above the southern horizon during the summer months. Astronomical darkness only returns in early August from this location. So imaging opportunities are few from this cloudy location. Here it was imaged at 13 degrees above the horizon. It is also so faint it is difficult to locate unless it passes by something significant - like a star cluster. So M25 was well placed.

Location verified with Skychart and ucac3 catalog.
