The Veil Nebula is a remnant of a
supernova that exploded some
5000 years ago -- it lies in the
constellation Cygnus, and is about
1400 lightyears away. Shown here
is the brighter eastern portion of
the Veil, designated NGC 6992.
Please compare the field of view
with another image of
this region,
taken with the longer focal length
RC scope. Also, please contrast
this image with the western portion
of the supernova remnant, "The
Witch's Broom Nebula, aka
NGC
6990
. It is interesting to speculate
what our sky might have looked
like in the hours/days following the
cataclysm -- estimates are that it
appeared as bright as a crescent
moon!
