D escription: - A
bright nebula in the central region of Cygnus with the Milky Way
stars as the background. This is a more recent wide field view
compared to my first attempt at it in the image below. We were
dealing with gusty winds and bands of thin cloud that ruined
some sub-exposures. Next time I plan to try longer exposures to
get more of the subtle background Ha emissions in the region.
