Move your mouse over the picture to see the names of the various craters.
Schickard is the largest crater on the visible side of the Moon with a diameter of 233 Km.
Because of its position near the western limb, it appears eliptical when in fact it is circlar.
To emphasise this effect, I have added a third, 100 Km, scale marker in a direction corresponding
approximately to the direction of minimum scale. To the south of Schickard are Nasmyth, 80 Km
in diamter and 2300 metres deep, and Phocylides which is 117 Km in diameter.
The picture was taken with a ToUcam attached to my LX200 on 25th October 2004 at 22:26 UT,
when the Moon was 12.6 days old.
A mosaic of this picture and the two to the south can be seen here.

Processing: Registax. 102 frames stacked. Wavelet 1,2 = 10
And here is the same area with the light coming from the opposite side. (I regret
that the image is rather differently orientated too.) The picture above was taken
at day 12.6 and this one at day 26.3 when the Moon was a small crescent in the morning sky.
It is also taken in infra-red light which helps to remove the glow in the sky
caused by the imminent dawn.
The picture was taken with a ToUcam attached to my LX200 on 31st August 2005 at 04:38 UT,
when the Moon was 26.3 days old.
Date and Time: 31st August 2005 at 04:38 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus with IR-pass filter
Capture: K3CCDTools. Low gamma, 1/25", 61% gain, 393 frames
Processing: Registax. 80 frames stacked. Wavelet 1,2 = 10
Essentially the same area but imaged a day earlier. This results in much shorter shadows and a generally blander image. However the Hainzel triplet is showing at the top of the picture. The picture was taken at sunrise, so lacked contrast for that reason too (hence the extreme stetch of the histogram).
The picture was taken with a ToUcam attached to my LX200 on 17th October 2006, when the Moon was 26.3 days old.

This is a mosaic of two pictures of Schickard and the area to its north. It is rather too big to fit on this page so I have reduced it to 63%. Click on the image to see the picture at full size in a new window.
