Move your mouse over the picture to see the names of the various craters. You may have to scroll the picture to see the eastern end.
This is a mosaic of three exposures taken of the north polar area. The
libration was favourable at 5° 4' in latitude. Currently the libration
is particularly good for the northern areas in August but the Moon is also very low in the sky from Britain
which makes it more difficult to image. September is a compromise. I have marked
the position of the pole as best I can determine it and the arrow points down the
prime meridian.
Scale markers are rather pointless in a picture of this area.
Any line pointing to the north pole is north; Anaxagorus, at 73.4° N, is about a degree north of Philolaus and
a degree south of Pascal. Scale also changes considerably both with position and
direction. As a guide, some of the more-prominent craters have the following diameters:
Anaxogorus 53 Km, Philolaus 73 Km, Pascal 103 Km, Pythogorus 133 Km, Carpenter 70 Km, Byrd 97 Km,
Peary 77 Km.
The picture was taken with a ToUcam attached to my LX200 on 16th September 2005 at about 20:45 UT,
when the Moon was 13.4 days old.
