LBN 577 Sh 2-170 Little "Rosette"

The Small Rosette Nebula (Sh 2-170), also known as LBN 577. In the late 1950s, American astronomer Stewart Sharpless discovered the large nebula Sh 2-170 on photographic plates from the 48-inch Schmidt telescope of the Palomar Observatory Sky Survey. In 1959, he published his discovery along with 313 H-II regions in a catalog. He classified it as a round structure, between amorphous and filamentary, with medium brightness and a diameter of 20 arcminutes. [310] In the "Catalogue of Bright Nebulae" by Beverly Lynds, published in 1965, this nebula is listed as LBN 117.62+02.29 or LBN 577. [270] The nebula resembles the larger and brighter Rosette Nebula (NGC 2237), hence its nickname "Small Rosette Nebula." I captured this back in winter, in January. I shot a little, stacked the data, and then forgot about it. Since I took the shots, I might as well share them.
