Sh2-124 (2025)

This is my version of Sharpless 124 (Sh2-124) which is a dim emission nebula located in the constellation of Cygnus. It lies approximately 8500 light-years from us meaning the light began its journey when humans were shifting from hunting and gathering to agriculture. The nebula is composed mostly of hydrogen gas but there was a fair amount of oxygen and sulfur as well. Originally I planned on doing just hydrogen and oxygen but I have to thank astrophotographer Rodd Dryfus (image) who recommended including sulfur since it provided more depth than just the Ha and OIII (he had done it both ways).

There are a lot of dark nebulae in this region as well as unnamed dustlanes which I really like. There is a small Planetary Nebula, PN G094 +00.8, on the left central region of my image. I see a small round red blue splotch that looks like it could be a PN but charts indicate the PN is just above that. Not sure if the charts are off or if one of the tiny stars above is the PN. Lastly, this region sits in a heavy starfield and although I prefer not to do star reduction, sometimes it is necessary. The starfield is still quite colorful and rich.

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.
