Infrequent ramblings while meandering around the world

Moon from last night on the west coast (shot through a window!)
The crater at the 12 o'clock position, approx 1/8" from the edge is
Crater Endymion which is approx 125km in diameter.
The dark crater between 10 and 11 o'clock, approx 1/3" from edge is
Crater Plato which is approx 100kms in diameter.
The large visible craters on the right side of the moon (T to B)
Langrenius, Petavius and Fumerius.

Some folks have asked me about the hardware required for this shot.
It was taken with a slow 600mm F/8 refractor (stopped down to F11)
on a APS-C sensor (Nikon D200). The APS-C sensor provides a 1.5 crop
factor for all lenses which means the 600mm is actually closer to 900mm for this shot. The shot has a 1/250 sec exposure.

There was minimal post production work on this shot,
almost appears as taken on the night. The image is a little soft
as it was taken through a window.
