Notes
Sharpless 2-278 is a faint HII region lying on a line halfway between Beta Orionis (Rigel) and Eta Orionis. The constellation Orion has a great number of these "dusty" objects to interest the astro-imager. Sharpless 2-278 reminds me of two of my favorite such dark objects in Orion; Barnard 30 and LDN 1622.
