The floor of Mare Orientale
On the evening of September 28, I managed to photograph the flat floor of Mare Orientale, which is seldom
visible from earth. The non-circularity of the moon's orbit makes it swing into view occasionally.
Compare my earlier success here, under even better conditions.
Celestron 5 (5-inch telescope), best 25% of 4,994 video frames taken with a ToupTek 678 camera,
aligned, stacked, and sharpened.

Lit from the other direction
Now scroll through this view of Mare Crisium and its environs.
This is the region of the moon that you would see as a thin crescent in the evening, except that here,
we're seeing it when the moon is slightly past full, and if you were standing on the moon in this region,
the sun would be setting rather than rising.
Lots of familiar details are lit from the opposite of the direction we're accustomed to looking at.
Same setup as before, best 50% of 3,821 video frames.

First glimpse of Saturn
Finally, with the same setup, I got the season's first view of Saturn.
This is not a very good picture; the telescope was too small; but it does show you
what Saturn looks like in a small telescope. Best 800 out of 2,387 video frames.
