7/16/2010 Challenging M20 again this year.再挑戦 5/31/2015 Reprocessed!!! This photo is synthesized for mimicing the effect of H-alpha (red light) emission, that is almost cut off by the infrared filter, commonly used in all the commercial cameras. First, the trifid part of the nebula is cut out and its red color is intensified and then overlaid on the original photo.
