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 microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is the brighter of the two stars (lower star) in close vertical proximity just to the right of Sh2-101 in the image presented here.[2]

This image is compiled from 56 hours of narrowband data and processed in PixInsight. The images are each 30 minute with 41 Ha images, 39 OIII, and 36 SII. Three different presentations are given with SHO, HSO, and HOS. Data aquired using ACP Expert starting on September 14, 2016 and continuing through July 9, 2017. Additional data still being acquired with a goal of 80 hours total.
