This is part 1 of a bigger mosaic that i’m planning to shoot. It shows a small part of the Cygnus nebular complex with the Crescent Nebula at his center.
The Crescent Nebula is an emission nebula probably formed by the outer layers of a Wolf-Rayet star found at its center.
This is a merge of an HOO image taken with a Canon photo lens and an HRGB image taken one year ago with a 200/1000 newtonian.
