Move your mouse over the picture to see the names of some of the features.
Click here to see a mosaic of six pictures of this area.
Arzachel is 100 Km in diameter and very deep at 3600 metres. It is a little younger than the
craters to the north at about 3,900 million years. The floor is flat with a central mountain 1500 metres
high with a small crater on its southern slopes. One rille is visible on the eastern side of the floor
and is some 50 Km long.
Alpetragius, 41 Km in diameter, is very deep at 3900 metres, and has a large central mountain. An interesting
valley connects Parrot C to Lacaille C and seems to line up with a series of grooves extending off the top
of the picture.
The picture was taken with a ToUcam attached to my LX200 with a X2 adaptor lens on 6th September 2004
when the Moon was 21.8 days old.
Date and Time: 6th September 2004 04:36 UT
Camera: ToUcam 740K
Telescope: LX200 with X2 lens
Capture: K3CCDTools. High gamma, 1/50", 31% gain, 309 frames
Processing: Registax. 142 frames stacked. Wavelet 1,2 = 10
And here is Arzachel at sunrise. The picture is slightly bigger than the one above although taken
with the same telescope and lens. The Moon was slightly closer when this picture
was taken at 386,054 Km compard to 402,116 Km when the picture above was taken.
Hovever I'm not convinced this is the only explanation.
The picture was taken with a ToUcam attached to my LX200 with a X2 adaptor lens on 19th December 2004
when the Moon was 8.4 days old.
The scale markers are approximately 50 Km north and west.
