Moiré Eye

Another amateur image with the 33" Pic du Midi astounds with its orbiter-like resolution. The obvious star of the image is Aristarchus, with hair-like strands of bright rays draped over the walls and extending out toward Herodotus. The right angle crossing of these wall strands with terraces creates almost a moiré pattern on the left wall. The floor of impact melt and bouldery debris are clearly visible. Also easily seen are the Aristarchus Rilles - lava channels - and the narrow inner rille of Schröter's Valley. Even the very small rille just left of Herodotus is shown. Anyone else with a 33" aperture (not focal length) telescope - please send in your photos! (And I also welcome images from folks with smaller scopes).
