When it comes to atoms, language can be used only as in poetry.
The poet, too, is not nearly so concerned with describing facts
as with creating images.

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.
