Hadley Rille

Move your mouse over the picture to see the names of the various features.

These are the Lunar Apennine Mountains, south-east of the crater Archimedes.  I have managed to capture Hadley Rille, visited in 1971 by the Apollo 15 astronauts. The rille is about 1.5 Km wide and about 300 metres deep.  Its proximity to the mountains demanded great precision in navigation of the lunar lander, which approached from the east. I am indebted to Steve B., of the QCUIAG group, for providing this picture comparing my picture with one by NASA showing the rille very clearly. My picture was taken with a ToUcam attached to my ETX125 with a X2 lens attached on 4th September 2004, when the Moon was 19.9 days old.
