Description:
I've heard of this object being viewed from even farther north than this.  But
I never thought I'd see it from here due to the poor transparency near the 
horizon here in Missouri.  We also have a hill about 1/2 mile to our south with
tall trees on it.  But my friend Kim Colter solved this problem by observing 
from the top of the 17' ladder.  When it was my turn to take a look I was amazed
at how bright and easy it was to see.  It would almost certainly have been 
visible in 50mm binoculars.  I may try to get a look at it from a better site
with the 13" to see if any stars can be resolved.  This was a very memorable 
site for me.  I can't remember the last time I observed a deepsky object that 
shared the field of view with a tree!
