Default ASTRO: 4.5 day old moon (ATTN Rick)

Yep, I continue with my moon mosaics ;-)
This one is build out of 13 RAW images. Still no really clear skies
(thin,
high clouds) but I managed.

Petavius, with its huge rill has always been a favorite of mine. I was
reading some astronomy text from over 100 years ago in which the author
suggested it was a canal to bring water from snow capped peaks to lunar
folk in the valley between the two ramparts of Petavius' walls. Never
could figure out if he was serious or not. This was before the canal
craze on Mars so not a spoof of Lowell. Maybe he was serious, I don't
know but I've always liked the crater after reading that book. Found it
in the stacks of the University of Nebraska's physics library. It was
falling apart but a fun read to see how astronomy had changed.

Ha, cool story again :-) Made a Petavius focus for ya .. plus curiousity
from my site :-)
Again: really love RAW format: so much can be done with it in image
processing :-)

That's an excellent shot. I never did as well with the 10" scope.
