NGC 1491

Emission Nebula (Hydrogen plasma)

Exposure:                   LRGB = 60 min each, H alpha 110 min. H alpha blended with red channel and luminance.
Date:                           Dec. 29, 2008 - Jan. 1, 2009
Comments:                This is only a small part of an extremely large area of nebulosity called Sharpless-206. So the reddish nebulosity extends far beyond the edges of this image.
