Description

Sharpless 101 (Sh2-101) is an emission nebula in the constellation Cygnus, also known as the Tulip Nebula. This object is also famous for being close to Cygnus X-1, one of the first objects to be classified as a black hole, at about 21.2 times the mass of the Sun. This black hole is a binary system with a giant blue star orbiting it. It has a pair of relativistic jets perpendicular to the accretion disk of the black hole. These jets interact with the dense interstellar medium around it, forming a bow shock that is visible as an arc of bluish faint light close to the Tulip in this image. The proximity between these objects is just perspective, given that Sh2-101 is around 6000 light years from earth, while Cygnus X-1 is 2.22 kiloparsecs (*) away.

Also in the field is NGC6871, a cluster of approximately 50 young blue and white stars, as well as several other objects from the LDN and LBN catalogs.

I wanted to give this field of view another night of collecting data including RGB stars but the weather turned and I decided to process it. I made heavy use of the GHS script to stretch the image

(*) 1 kiloparsec = 3261.56 light-years
