Caldwell C9

Caldwell C9

The Cave Nebula, aka Sh2-155 and C9 is located in the constellation Cepheus.  This one hour 5min image appears to be a "cave entrance" thus the name of the nebula.  It is extremely large in area (15') and appears well in Ha.  There are lots of beautiful color images on the net.  Tried to get 2 hrs but had tracking problems due to mount reaching past the meridian.
