Lynds Dark Nebula 1251 in Cepheus

Description

LDN 1251 is a very faint nebula in Cepheus. Visible in the far lower left part of this image is the ruby red colored Carbon Star NIKC 5-20. A carbon star is a late-type star similar to a red giant (or occasionally to a red dwarf) whose atmosphere contains more carbon than oxygen; the two elements combine in the upper layers of the star, forming carbon monoxide, which consumes all the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a sooty atmosphere and a strikingly ruby red appearance. (Credit Wikipedia). Also shown are several YSO's (young stellar objects), and several very distant galaxies. Imaging Details: Televue NP127is f5.2 refractor at f4.2 with TV focal reducer; Atik 383L+ at -18 deg C; Orion EQ-G mount;TS OAG; Astrodon E series LRGB filters: 10.5 hours Luminance; 90/135/180 minutes R/G/B. Total exposure: about 17 hours over three nights in July 2014 at Grandview. Thanks for looking!
