Tulip Nebula

SH2-101, also known as the Tulip nebula, is a bright nebula in Cygnus with the brightest part shaped like a tulip with the petals open toward the lower left corner in this image. According to Wikipedia - It was cataloged by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6000 light-years (5.710^16 km; 3.510^16 mi) from Earth. The companion star of the black hole, Cygnus-X1, is also in the field - the top reddish star of a red and white pair of stars just to the upper left of the Tulip.

The image was taken from rural, but not extremely dark skies using an Optolong L-eNhance filter to increase the contrast in the nebula. As the exposure was short and the seeing poor, the image has been binned two by two in post processing to reduce it for web display and to increase the SNR.

Compare this result to my original quick and dirty pass at processing just to see how much gas and dust was in the field. Although it produced more background cloud structure, it falls under what I tend to describe as a monochrome red presentation. This happens when I don't pay attention to the colour balance during my initial stretch and then emphasize the very weak red signal too much during colour balancing.
