The Crescent Nebula - NGC6888

crescent v3-2hrs

NGC 6888, also known as the Crescent Nebula, is a faint emission nebula in the constellation of Cygnus. Although shining at magnitude +7.4, its extremely low surface brightness means a very transparent night or quality optics coupled with a nebula filter is required to spot it.

This nebula is located in a dense region of the northern Milky Way. Positioned 2.75 degrees to the northeast is bright star, Sadr (γ Cyg - mag. +2.23), with open cluster, M29, just over a couple of degrees directly east of the nebula. NGC 6888 was discovered by William Herschel on December 15, 1792 and is best seen from northern latitudes during the months of July, August and September. It's object 27 in the Caldwell catalogue. This image was taken over two nights, October 27 and October 29, 2019,  with a one hour exposure for each night.
