Description

This was a multi-night effort of the Tulip Nebula SH2-101, processed in SHO.   Lots of data with this one and I'll likely try some additional variants.
Per wikipedia.https://en.wikipedia.org/wiki/Sh2-101.   Sharpless 101 (Sh2-101) is a H II region[1]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.
