High noon is when gunfighters meet on main street in western movies, And its when topography disappears and only variations in reflectivities are visible. In Jean-Marc's high contrast and strong tonality image the gray rays of Aristarchus streak away beyond a rough dark halo. One ray comes from between Aristarchus and Prinz and strangely seems to turn outward, very much non-radial. The rays are nearly invisible over the pyroclastic darkness of the Aristarchus Plateau, although they can be clearly seen on the maria beyond the Plateau at upper right, and are barely noticeable to lower right. An obvious interpretation would be that the ash on the Plateau is younger than Aristarchus, but that is wrong. Aristarchus is one of the youngest medium sized craters on the Moon, perhaps 500 million years old, and the pyroclastics are more than 3 billion years old. The rays simply are not very visible on the ash; perhaps someone will explain why.<br /><br />

<strong>Technical Details</strong><br /><br />
August 6th, 2007. 10&quot; Cassegrain telescope + a blue filter + Skynyx 2-2M, 200 stacked images. Jean-Marc re-processed the left image with [http://hdrsoft.com/ Photomatix Pro], a High Dynamic Range photography software. The tool &quot;tone mapping&quot; was used to enhance contrast; the process is described [http://astrosurf.com/lecleire/hdr/ here] (and CAW further stretched the image).<br /><br />
