Image of the Archimedes and Mons Hadley region. Image taken from home in London on 09th March using a 200mm SCT telescope and an Imaging Source camera. A 60 second AVI file is recorded at 15 frames per second and then the frames are stacked in Registax software to reduce the detrimental affects of the atmosphere and then tweaked to bring out the detail. Hadley Rille can just be made out.
Archimedes and Hadley Rille
The site of the Apollo 15 landing on 30th July 1971, just to the East of hadley Rille is circled in the close up from the same image below:

The first use of lunar rover which travelled a total distance of 27KM on the Apollo 15 mission. Image below is of David Scott and the rover at the very eastern edge of Hadley Rille.

Apollo 15 was the fourth manned mission to the Moon and was considered at the time to be one of the most successful, the 2 astronauts who actually landed David Scott and James Irwin stayed for just under 3 days before heading back home.

A few more images of the Moon from Sunday 09th March along with an accompanying tune:
Wallace and Mons Ampere region
Wallace is the remains of a crater that has been flooded by lava just to the left of centre in this image. It lies in the southeastern part of Mare Imbrium and is approximately 27km in diameter with the rim approximately 400 metres about the surrounding area. The mountains are the Mons Ampere range, some of which reach height of approximately 3000 metres and are thought to have formed about 3.5 billion years ago.
Ptolemaeus & Alphonsus
Ptolemaeus is the largest crater in the above image at approximately 150km in diameter and forms a lovely trio with Alphonsus centre and Arzachel bottom. Ptolemaeus is believed to have formed about 4 billion years ago and has a very flat lava filled floor with a single prominent craterlet Ammonius to the North East which itself is some 9km in diameter. Alphonsus is slightly smaller at 118km diameter and has a prominent central mountain caused by uplift that followed the impact at time of formation about 3.85 billion years ago. The steep perimeter walls rise to some 800m.
Plato & Montes Alpes
Plato is the large crater to the West lying in part shadow of the terminator. Plato is some 100km in diameter named after the 5th century BC greek Philosopher. The Lunar Alpes mountain region is also accentuated by the shadow and some of the peaks in this range extend to a height of 3600 metres. The Vallis Alpes is an immense 166 km long by 10km wide rille or lunar valley running South-West North-East with raised cliffs on each side with a flat lava filled surface.
A couple of images from a brief observing session on Sunday 09th March.
First up is Jupiter which is high in the sky at the moment. Early evening 18:30-19:00.
The moon Io can be seen to the upper left and its shadow can be seen transiting across the face of the planet. The great red spot can also be seen.
Next stop the Moon – The area below is in the southeast corner of Mare Nubium – Just below centre right is a neat little triple crater formation called Thebit , Thebit A lies across the rim of this crater and the rim of Thebit A is overlain in turn by the even smaller Thebit L. The largest of these little craters is just under 60km wide and 3km deep. Adjacent, to the left is is a 110-kilometer-long rille named Rupes Recta, more commonly known as the Straight Wall which rises to a height 240 metres.
One of the first footsteps on the Moon. It was made by Buzz Aldrin on 20th July 1969 during the Apollo 11 mission.
Staying on the crater theme for a bit, the image above is of the central peaks of the prominent crater Tycho on the Moon.
The mountainous formation above is some 15km across and rises 2km from the base of the crater which was formed relatively recently some 100 million years ago.
The central peak forms directly following impact and is due to a phenomena known as uplift which occurs in the larger craters and is due to complex interactions between shock waves, the force of impact and the inherent strength of the impacted area as well as gravity.
This image was obtained at lunar sun rise on 10th June 2011 by the Lunar Reconnaissance Orbiter and shows the central peak casting a long shadow and captures amazing detail at incredible resolution.
Zooming in a little closer, individual boulders can be picked out on the peak, the largest in the image below is 120m in size, the overall image is 1200m across approximately:
The Tyco crater is a prominent impact crater located on the southern highlands and is named after the Danish astronomer Tycho Brahe. The crater has an extensive ejecta that radiates out in a spoke formation some 1500km or so from the central crater.
An image of the Tyco crater in its full glory from the LPO and another as seen from London are shown below:
