Sh2-101
Image Description and Details : Sharpless 101 (Sh2-101) is a H II region 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 catalogue 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. 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 can be seen as an arc (bluish) to the right of the "Tulip".

The Tulip
Image Description and Details : This colourful region, located in the constellation Cygnus, has many distinct views of energized gas, all of which give a deep sense of wonder and amazement. The night sky is wonderful, always look up!
We are star dust.

cygnus mosaic
I have started this imaging project back at 2010. My aim was to make a high resolution mosaic covering the constellation Cygnus. Work like that takes time and patience, especially since I have worked so, that many of the individual sub mosaics or frames have been published as an individual artworks. Here is a poster format presentation about all of longer focal length images used for this mosaic beside wide field panels.
As a result I have now a huge 37 panel (And 58 long focal length sub-panel) mosaic panorama covering 28 x 18 degrees of sky. I have collected photons way over 600 hours during past ten years for this photo. The full size mosaic image has a size of about 25.000 x 15.000 pixels.
In the orientation image above, there are three large supernova remnants visible, first the Cygnus Shell W63 , bluish ring at upper left quarter, secondly the large SNR G65.3+5.7 at utmost right and finally the third is a brighter SNR, the Veil nebula just outside of field of view at bottom center. (Image is partly overlapping with large mosaic but I didn't want to include it yet due to artistic composition.)Beside three supernova remnants there are two Wolf Rayet stars with outer shell formations. NGC 6888, the Crescent Nebula at center of the image and the WR 134, it can be seen as a blue arch just right from the Crescent Nebula, near the Tulip nebula.Next to the Tulip Nebula lays a Black hole Cygnus X-1, it's marked in small closeup image of the Tulip Neula at center right in orientation image above.
There are 37 base panels with shorter focal length tools (300mm f2.8 Tokina and 200mm f1.8 Canon) There is also 59 sub-panels used, they are shot with my old 12" Meade and 11" Celestron Edge scopes.
