The Eastern Veil
June 20/21. Approaching the shortest night now, and during a couple of hours of cloudless skies last night I continued the examination of the rich Cygnus area, this time looking at C 33, the Eastern Veil Nebula. Along with the Witch’s Broom, this forms part of the Cygnus Loop supernova remnant.
The blue areas are O III, doubly ionised oxygen, the red areas are ionised hydrogen. I would have given it longer but clouds rolled in.
