Caldwell 33, popularly known as the Eastern Veil, is a supernova remnant (NGC 6992) in Cygnus — the glowing wreckage of an exploded star. It appears as number 33 in the Caldwell catalogue, Sir Patrick Moore's 1995 list of 109 bright deep-sky objects for amateur astronomers. It spans roughly 60 arc-minutes on the sky. It is one of the showpiece objects Sir Patrick Moore chose for his Caldwell list of bright targets the Messier catalogue left out.
Although it appears about 60′ wide on the sky, its real span is roughly 41.9 light-years — the difference is a measure of how far away it lies.
Observing Eastern Veil
Eastern Veil lies in the constellation Cygnus and is best placed in the evening sky around August. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the northern hemisphere, and sits low for those far south.
