The Horsehead Nebula in Orion
The Horsehead is a striking dark nebula located
just below the belt of Orion. Photography of this nebula, especially with film,
is a major challenge! It is very small
(about 4x6 minutes) and too faint to see visually in my scopes. The reddish background emission nebula against which
the Horse is silhouetted is IC 434. You can see a comparison of this image with
an earlier version of the processing at Horsehead-ccd.
