The Milky Way in Cygnus

Cygnus is a great vista even to the naked eye observer. Along the Lyra, the Northern Cross rules the region also featuring a bright patch of the Milky Way which the experienced amateur astronomer knows is loaded with deep sky objects. I decided to take a deep wide angle look at this iconic part of the northern sky. Although the lens used is a toy compared to other takes, I am pleased by the results. Prominent dso’s in the frame: NGC 7000 – North America nebula; IC 5070, IC 5067 – the Pelican nebula; Caldwell 33, 34 – the Veil nebula; open cluster NGC 6940; although not obvious, C 27,  NGC 6888 Crescent nebula; IC 1318 the Sadr (γ Cygni) Region, and so on.  Photons collected on 2016-11-20, 21×3 min, Canon 1100D mod, ISO 1600, Canon EF 50mm f​/1.8 II @ f/4, HEQ5, used my star handler.
