At 100X in the 13" with no filter this nebula is pretty faint, large,
irregularly round and has a pretty low surface brightness.  It is 
visible, but no obvious.  There are 10 stars involved, including a triple
on the NW side of the nebula.  Adding the UHC filter at 100X is much
better, the nebulosity is unmistakeable.  Not so much larger in size,
but it has a lot more contrast.  The nebula is shaped like a shrimp,
however there are members of the Saguaro Astronomy Club who call it
the "Pac Man" nebula.  Either way, a fascinating shape.
