Rheita and Metius Home

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

The crater Rheita is 71 Km in diameter with walls 4000 metres high.  It is situated in the rugged highlands in the Moon's south-eastern quadrant. This is not an easy area to image.  The Vallis Rheita is a string of overlapping craters which starts on the western edge of Rheita crater and extends all the way down to the terminator, in all about 500 Km long.  I have a little more discussion of this valley here.  Metius is slightly bigger than Rheita at 90 Km and is 3000 metres deep.
The picture was taken with a ToUcam attached to my LX200 on 1st September 2004, when the Moon was 17.7 days old and the libration was almost exactly neutral.

Date and Time: 1st September 2004 23:46 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus
Capture: High gamma, 1/250", 15% gain, 313 frames
Processing: Registax. 45 frames stacked. Wavelet 1,2 = 10, 3 = 5
This is the same area and the same phase but the libration was almost as good as it gets for this part of the Moon, so the view is slightly different and more of the southern part of the Rheita valley has come into view.
The picture was taken with a ToUcam attached to my LX200 on 18th November 2005, when the Moon was 17.6 days old.
