thanks Dave.. I thought the very skinny dark lane that I have yet to
observe visually 
was an error, (the one coming off the middle of the "Y") until I found it
in older ccd images, I think I overprocessed a bit, and the contrast is
unusually strong, it isn't going to be a super-noticeable feature visually.
The little propeller "X" is visually very, very apparent and bright in the
18" (I wonder if you can see it in an 8"?) and well worth the look, it
points to the other features within the cluster, etc. It's more asymetric
than other globulars, and you can have a field day with it even in suburban
skies. 
thanks again.. I worked (too) long on the M81 image and greatly appreciate
your comments.
Thanks!   -Todd
