The Moon

A composite of three images of the Moon on the 28th May 2012 taken through my 127mm refractor.
The enhanced colour reflects the differences in mineral makeup of the Moon's crust 
(the colour information was added from an image taken some time ago using my ETX90 RA)


As the atmosphere was reasonably stable I decided to capture HD video clips at higher magnification using my Lumix compact camera fixed to my refracting telescope. The clips were then split, aligned and stacked using Registax 6 and the final images sharpened and enhanced using Photoshop.
The areas A and B were selected for enlargement as they were more or less on the terminator and showed interesting detail.

The darker area in the triangle formed by the Crater Archimedes and the mountains Hadly and Bradley exhibits a number of volcanic features including a 'Dome' Putredinis 4 which can be seen clearly in image A.

This NASA image shows the Apollo12 Lunar module over the crater Ptolemaeus. The small crater below and to the left of the space-craft is the crater Ammonius and the larger crater to the right is Herschel.
On board the Lunar module piloted by Alan Bean was the Mission Commander James 'Pete' Conrad. The Lunar module landed in the Sea of Storms (Oceanus Procellarum) on the 19th. of November 1969.
I was twenty years old when this mission was accomplished, the last person to walk on the Moon did so in 1972 when I was twenty three, I'm sixty three years old now and it begs the question as to whether I shall be alive to see the next man or the first woman to walk on the Moon!

The crater Ptolemaeus is approximately 153km across and 2.4 km deep. Its floor has been flooded with a basaltic lava and a number of 'Ghost craters' (ie.craters that have been flooded with lava but still show an impression of their rims) can be seen in Image B.
