Hmmm, I never thought of that. When I say "2 oclock", I mean that for
me, through an inverting telescope, the crater formation is at the upper
left limb (where 2 o'clock would be on the face of a clock). Since we
don't know if your telescope inverts, it could be either 2 or 8 o'clock.

Wait, would that be 8 o'clock or 4 o'clock? If it just flips it over
(ie, as a mirror image across the horizontal diameter), then 2:00 would
become 4:00. But if it actually rotates the image of the moon by 180
degrees, then you're right, it would be 8:00.

Joyce - knows very little about telescopes, but does know about image
transformations!
