M 27
Exposure: (L+Ha), R, G, B. (L = 120 min 1x1, RGB 60 min each, 2x2. H alpha 80 min, 1x1.)
Date: July 28-31, Aug 8, 2009 .
Comments: This 'planetary' nebula is surrounded by a dim halo which is more visible via a much deeper H alpha exposure than the one I obtained and used here. In this image only a slight portion of the halo can be glimpsed to the north-west (upper right) of the body of the object.
