Description

Tulip Nebula (SH2-101) and Cygnus x-1 (Black Hole)

As this summer becomes full swing so does our view of our galactic center and its inner workings. As I have been exploring Southern galactic view I wanted to image something spectacular or what maybe most of us deem spectacular like the pillars of creation or the lagoon (i am sure that i will capture them soon this fine nebula season) but they happen to be way to low in my horizon to begin imaging now. so i searched for over an hour trying to decide the next best thing skipping over the tulip many times, finally i gave up with frustration and decided to capture it and to my amazement it is actually spectacular and in line with the pillars or the lagoon with beautiful blues and golds as well as my favorite attribute the blue arch (Bow Shock) caused by a black hole!! its pretty cool to think that i have indirectly captured a black hole and directly captured visible effects caused by a black hole!! any way enjoy this is a single night capture so I may come back and gather much more integration on this one. 

Sharpless 101 (Sh2-101) is a H II region=10.5px emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.Sh2-101, at least in the field seen from Earth, is in close proximity to microquasarCygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is located about 15 west of Sh2-101. The companion star of Cygnus X-1 is a spectral class O9.7 Iab supergiant with a mass of 21 solar masses and 20 times the radius of the Sun. The period of the binary system is 5.8 days and the pair is separated by 0.2 astronomical units. The black hole has a mass of 15 solar masses and a Schwarzschild radius of 45 km. A bowshock is created by a jet of energetic particles from the black hole as they interact with the interstellar medium. It can be seen as an arc at the top of the photo on the left.
