Move your mouse over the picture to see the names of the various features.

Mare Imbrium This picture shows much of the north-west quadrant of the Moon, the Mare Imbrium and various features to the north.
It was taken with a ToUcam attached to my LX200 with a 0.33 focal reducer on 16th December 2003 at 04:47 UT, when the Moon was 21.6 days old.

Date and Time: 16th December 2003 04:47 UT
Camera: ToUcam 740K
Telescope: LX200 with Meade 0.33 focal reducer
Capture: K3CCDTools. 50% gamma, 1/500", 10% gain, 303 frames
Processing: Registax. 116 frames stacked. Wavelet 1 = 5


Mare Imbrium This picture, at the same scale as the one above, was taken when the Moon was 11.5 days old and shows the northern area east of Sinus Iridum.  There are plenty of named features in this area.  A slight difference in albedo (brightness) can be seen in the surface of Mare Imbrium which is more clearly seen in a exaggerated-colour version and implies that the eastern part of Mare Imbrium is covered in something different from the western side.  The same difference can be seen in a closer version imaged in infra-red light.
It was taken with a ToUcam attached to my LX200 with a 0.33 focal reducer on 12th November 2005 at 20:38 UT, when the Moon was 11.5 days old.

Date and Time: 12th November 2005 20:38 UT
Camera: ToUcam 740K
Telescope: LX200 with Meade 0.33 focal reducer, IR-block and Neodymium filters
Capture: K3CCDTools. 0% gamma, 1/100", 25% gain, 617 frames
Processing: Registax. 174 frames stacked. Wavelet 1 = 10, gamma 1.5, histogram 22-200


Mare Imbrium This is a picture of the far north taken a day after first quarter.  The libration in latitude is such that the north pole is tipped towards us, and the Sun was one degree north of the lunar equator, so the North Pole is displayed and in sunlight.  It is difficult to see exactly where the pole is in any picture taken from Earth, but it resides in a small crater on the rim of Peary.  In the mouseover I have indicated where I think it is with an arrow that points down the prime meridian, which passes through Epigenes A.
Because the libration (6°56') exeeds the solar angle (1°) the edge at the very top is the terminator not the limb.  This can be seen from the isolated mountain that is just catching the Sun on the top-left of the image.  I cannot identify this mountain (remarkably few mountains on the near side of the Moon have names let alone on the far side), but there is a massif between Peary and two large craters on the far side called Hermite and Rozhdestvenskiy.  I assume it is a high point in that mountain range.
The picture was taken with a DMK camera attached to my LX200 on 27th December 2017 at 19:14 UT, when the Moon was 8.8 days old.
