The bright star Sadr marks the chest of the constellation Cygnus, the Swan. Located in the direction of the northern Milky Way, this little patch of sky is packed with diffuse emission and dark nebulae that are part of the much larger Cygnus Molecular Cloud. This image by Terry Hancock shows the rich nebulosity in this region as captured from his backyard observatory in Fremont Michigan. He created this mosaic originally consisting of 5 panels and later cropped to make 4 panels using 187 individual frames and a total exposure time of over 18 hours. The total mosaic covers an area approximately 6.5 x 5.4 degrees. Equipment used, QHY11 Monochrome CCD and Takahashi E-180.

Here’s a short video created by Terry to take you on a further tour of this splendid part of the heavens:
