Two dark nebulae in M24 in Sagittarius
Two dark nebulae in M24 in Sagittarius
Lynds' Catalogue of Dark Nebulae (LDN 327 and 323) show up well in these two images. Of almost equal interest are the stars that are very bright in the infra-red but almost invisible in V (green) band. Are these stars very cool red giants or perhaps Carbon stars?. http://www.martin-nicholson.info/baa/darkregions2.htm Martin Nicholson, Daventry, England. http://www.martin-nicholson.info/1/1a.htm Visit the Astronomical Hall of Shame at http://www.geocities.com/queen5658/
