To the Far Side of the Moon--rare views from Earth
This image was taken at maximum libration in both latitude (south) and longitude (east), and therefore shows many features that are rarely observed from Earth. Of special interest in this image are the following features:
1. Shackleton crater, marking the true lunar South Pole.
2. Schrodinger crater (rim visible), a far side impact basin
3. Vallis Schrodinger, a long linear valley on the lunar far side.
4. Numerous far side craters visible near the limb (more details below).
Shackleton crater, marking the true South Pole of the Moon, is visible at the top right of the image, although locating it among the complex crater strewn landscape is not so simple. The rim of Shackleton is partially illuminated, whereas the interior experiences perpetual darkness. To the left of Shackleton, the elevated terrain on the lunar limb marks the perimeter of Schrodinger crater, a large impact basin on the lunar far side. The far side craters Ganswindt and Idel'son are clearly visible here, with Rittenhouse further to the left. Further still to the left, some features of Vallis Schrodinger can be observed on the extreme limb. Vallis Schrodinger is a linear valley on the lunar far side that likely formed during the Schrodinger impact. Vallis Schrodinger crosses through the far side crater Sikorsky, which is partially visible on the extreme limb of the image. Far side craters Chamberlin and Moulton (visible towards left of image, along the limb) lie at the northern terminus of the valley. And finally, at the lower left of the image, we see the edge of Mare Australe. Other notable features in the image include Vallis Rheita at lower left, Boussingault crater near top center (large crater with multiple terraces), polar craters Amundsen and Scott at top right, and a series of striking craters along the lunar terminator.
The image was captured with a C9.25 Edge HD telescope, ASI183mm camera, and 610nm long pass red/IR filter on July 20, 2018, at 03:17UT, from San Diego, CA. Focal length 2350mm @f/10. Stack of 500 frames. Software utilized: Autostakkert (version AS!3 for stacking), PixInsight, Photoshop.
