Move your mouse over the picture to see the names of the various craters.
Albategnius is an old crater dating from about 3,900 million years ago. This is indicated by
the way other craters appear on top of it; for example Klein to the West. It is 139 Km in diameter, has high walls and a flat floor
punctuated by a central mountain. The other great craters in this picture are in the SW
quadrant and larger-scale images of this whole area can be found in that section.
The picture was taken with a ToUcam attached to my ETX125 on 21st June 2003 at 0300 UT,
when the Moon was 21.6 days old.
Date and Time: 21st June 2003 03:00 UT
Camera: ToUcam 740K
Telescope: ETX125 at prime focus
Capture: K3CCDTools. High gamma, 1/50", 0% gain, 306 frames
Processing: Registax. 187 frames stacked. Wavelet 1-2 = 5
The picture above was taken in the evening on the Moon, and here is the same area
pictured in the lunar morning. Ptolemaeus and Alphonsus are in deep shadow,
but we can now see features to the east of Albategnius which were in shadow in the
earlier picture. This picture was taken through my LX200 which has a longer focal length
than the ETX, hence the larger scale.
The scale markers here are approximately 50 Km north and west.
The picture was taken with a ToUcam attached to my LX200 on 19th December 2004 18:03 UT,
when the Moon was 8.4 days old.
Date and Time: 19th December 2004 18:03 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus
Capture: K3CCDTools. High gamma, 1/250", 9% gain, 326 frames
Processing: Registax. 95 frames stacked. Wavelet 1-3 = 10, histogram 0-200, contrast 80
The picture was also taken in the morning on the Moon but about 12 hours earlier than the picture above. Ptolemaeus and Alphonsus are in deeper shadow. This picture was taken in infra-red light during the day time (69 minutes before sunset)
The scale markers here are approximately 50 Km north and west.
The picture was taken with a ToUcam attached to my LX200 on 5th May 2006,
when the Moon was 7.9 days old.
Date and Time: 5th May 2006 18:24 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus with IR-pass filter
Capture: K3CCDTools. Low gamma, 1/33", 25% gain, 420 frames
Processing: Registax. 221 frames stacked. Wavelets 1 = 10, 2 = 5, gamma 1.4, contrast 160, brightness -20
PhotoImpact. Gamma 1.3, contrast 45
And now a close-up picture of Albategnius. Although this picture was taken only about 5 hours (lunar time) after the picture at the top of this page, the Sun was significantly lower in the lunar sky as can be seen from the fact that Klein is almost completely in the shadow of its 1500-metre western wall; even its central mountain is in darkness.
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 04:40 UT
Camera: ToUcam 740K
Telescope: LX200 with X2 lens
Capture: K3CCDTools. High gamma, 1/50", 31% gain, 306 frames
Processing: Registax. 193 frames stacked. Wavelet 1,2 = 10
This is essentially the same view of Albategnius but in the lunar morning.
I have been experimenting with the reduction of noise in my pictures using NeatImage. Move your mouse over this image to see that this process can be overdone.

This is essentially the same view of Albategnius but earlier in the lunar morning.
I have been experimenting with the Gaussian wavelets in RegiStax6. This picture is with the wavelets linked; move your mouse pointer over the image to see the effect of unlinking the wavelets.
I am puzzled by lines across several of the craters. They have to be artefacts and are certainly enhanced by the processing but I believe they are there on the original image. What are they?
The picture was taken with a DMK camera attached to my LX200 with a X2 adaptor lens on 10th April 2011 when the Moon was 6.7 days old.
