LBN 575 (2025)

This is my version of LBN 575 and a portion of LBN 573 located in the constellation Cepheus. Both are faint reflection nebulae illuminated by scattered light from nearby stars. LBN 575, the lower region contains LDN 1259, LDN 1261 and LDN 1262. LDN 1262 is the darkest portion and reportedly houses a number of Herbig-Haro objects although none are visible in my image. LBN 573 is located in the upper portion of the image but not all of it was captured. There is a lot of dust and gas in the background as evidenced by the faint nebulosity. I also like the rich and colorful starfield that this molecular cloud rests in.
