John;

Seems we have a bit more in common than OM.  I've got a Meade 8"  LX200
computerized zippadeedoodah scope.  Love it, but don't have enuf time to use it
as much as I'd like.  Have taken some Hale-Bopp with it (piggyback only). C-11
is a real light-bucket. Would have liked to have gotten the Meade 10" but
funding was limited.  Where do you go to observe and photograph?
