I can't believe the 10" Teeter scope is still available in the classifieds. If I didn't already have 2 10's I'd jump on it myself. Fact is I've looked through this scope and at F/6 it's really incredible. Best view of Jupiter I ever saw through a 10" along with my Teleport. Up here in the Northeast 10" is a very good size performance-wise when you consider cool-down time. Anyway, just thought I'd throw that out there.
