Almost Microgeology
image by George Tarsoudis, Greece
It used to be that there were professional astronomers and amateurs. But now, with this image and others that LPOD has featured recently,
there is only excellent imaging, whether from a giant telescope, a backyard one or an orbiting camera. I am amazed to see a terrestrial image
of this scale and quality. The dramatic lighting highlights the ejecta from Theophilus, with the smooth impact melt ponds just north of the
crater's rim. Also very conspicuous is a small rille that looks like a twig with branches at the top end. This has been imaged before but it is
more distinctive here.

The rille also crosses a circular rise that George proposes is a megadome similar to the Valentine Dome. The dome (outlined
