About the image:

This image is a true colour RGB image shot on the ZWO ASI 533 MC Pro Cooled astronomy camera using the Optalong L-Enhance filter. The Tulip Nebula, listed as SH2-101 or Sharpless 101, is a H II emission nebula found in the constellation of Cygnus. This is an interesting nebula as, although my telescope doesn't have the power to resolve certain types of objects, close by the nebula lies a Micro Quasar known as Cygnus X-1, which is one of the first suspected Black Holes. The companion of Cygnus X-1 is a blue Supergiant with a mass 21 times greater than our own sun and is 20 times the radius of our sun and orbit each other in a mere 5.8 days.
