Sharpless 101 (Sh2-101) also known as the Tulip Nebula is yet another gem found in Cygnus located about 8,000 light years. Stewart Sharpless cataloged this Ha region in his 1959 catalog of Ha emission nebula. Located near the center of the nebula are two bright yellow stars and a very bright blue-white star called HDE 227018. This area is also home to Cygnus X-1, a microquasar which is the bright star half the distance from the nebula to the edge of the right side of the image. This is one of the most intense X-ray sources measurable from Earth, probably attributable to the presence of a black hole.
I have seen many incredible SHO image of this recently so me trying to be different did in Ha and OIII. I might have picked up more detail with sulfur but I did get a lot of detail in the nebula itself. This image also is far superior from the image I took of back in 2018. It was one of the last images I did with my old setup (Orion ED80 and modified Canon T3i/600D).

I thought I had decent data but the skies were too cruddy and so after examining the subframes closely I saw that they were very poor.
