Like the nearby "North America Nebula" consists the Pelican Nebula mostly of glowing hydrogen ( red) and oxygen ( green-blue), which gives the whole nebula a pinkish color.

Your images are very good. I have recently done the Pelican witha modified Canon 350D, Skywatcher ED80, WO 0.8 focal reducer. I am getting a lot of bunching of stars in the corners. I notice you do not use a focal reducer. Would I be better off not using one?
