Comet impact crater on Earth.

The impact of an asteroid or comet several hundred million years ago, according to scientists, left scars in the landscape that are still visible in this International Space Station/Expedition 12 picture of an area in the Sahara Desert of northern Chad.

Langrenus & Petavius 7th Nov 2006

6 image mosaic, using 2.5 x Tele vue Powermate.

Plato 2nd Nov 2006

4 image mosaic, Celestron 2x Barlow.

Moretus & Tycho 2nd Oct 2006

I was going to do one of those big sprawling 'walks' from Tycho to Moretus mosaics.
But the Clavius section didn't work out. It's amazing how much the seeing can vary from one moment to the next whilst imaging.

So here are the start and end bits, with the crappy middle bit sent to the null bucket ;-(

Aristarchus & Vallis Schröteri 3rd Nov 2006

Six image mosaic. Compare to this.
Vallis Schröteri is a sinuous valley on the surface of the Moon. It is located on a rise of continental ground, sometimes called the Aristarchus plateau, that is surrounded by the Oceanus Procellarum to the south and west and the Mare Imbrium to the northwest. At the southern edge of this rise are the craters Aristarchus and Herodotus.
This is the largest such sinuous valley formation on the Moon. It begins at a 6 km diameter crater located 25 km to the north of Herodotus. (The start of the valley has been termed the "Cobra's Head" by some observers, due to its resemblance to a snake.) From the crater it follows a meandering path, first to the north, then setting a course toward the northeast, before finally bending back to the south until it reaches a 1 km high precipice at the edge of the Oceanus Procellarum. The valley has a maximum width of about 10 km, then gradually narrows to less than a kilometer near its terminus.

The origins of this valley are believed to be volcanic. The interior floor has been resurfaced and is very level. However there is a slender rille located on the floor. This rille is not visible to observers on the Earth.

The selenographic coordinates of this valley are 26.2° N 50.8° W, and it has a maximum diameter of 168 km. It is named for Johannes H. Schröter.
