Summer stargazing on Dartmoor

Despite the short nights, and often poor weather, the summer night skies offer some spectacular celestial sights. My favourite areas to observe at this time of year are the rich swathes of the Milky Way in Cygnus, Sagittarius and Scutum. These regions are packed with dense starfields, glowing emission nebulae and some of the night sky’s finest star clusters.

On Saturday I spent the evening on Dartmoor imaging these wonderful parts of the sky. I wanted to capture a large portion of them in each frame, so I used a 50mm prime lens on my unmodified Canon 550D DSLR, which itself was mounted on an HEQ5 Pro mount.

The first image below shows part of the Sagittarius, Scutum & Serpens region. Several Messier objects are visible in the frame, including: M8 (the Lagoon Nebula), M20 (the Trifid Nebula), M22, M17, M16 (The Eagle Nebula) and M24. The second shot shows a region of the Milky Way in the constellation of Cygnus. The red glow of the North America Nebula (NGC 7000) and the nebulosity around the star Sadr (right of centre) are apparent. You can also, just, make out the two main fragments of the Veil Nebula right on the very bottom edge of the frame. The shot with the silhouetted tree is a single 15-second exposure, at ISO 1600, with the lens wide open at f/1.8.
