Mare Undarum Home

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

Mare Undarum is an irregular patch of lava south of Mare Crisium.  Its southern edge marks the position of the outer ring of the Crisium basin, but it takes a strong belief in such rings to see it here, (it only shows at all clearly between Geminus and Bernouilli, beyond the top of this picture).  The libration was favourable for the libration zone but unfortunately the lighting was not.  The picture was taken 20 hours after full Moon so the limb is in shadow.
The renaming of lettered craters has given me a problem here as Azout C is separated from Azout by Van Albada and Krogh (formally known as Azout A and B).
The scale markers are approximately 100 Km north and west.
The picture was taken with a ToUcam attached to my LX200 on 16th November 2005 at 20:47 UT, when the Moon was 15.5 days old.

Date and Time: 16th November 2005 20:47 UT
Camera: ToUcam 740K
Telescope: LX200 at prime focus with IR-pass filter
Capture: K3CCDTools. Low gamma, 1/33", 15% gain, 670 frames
Processing: Registax. 78 frames stacked. Wavelets 1 = 10, 2 = 5, gamma 0.8


The picture above was taken in the lunar afternoon, but this one was taken at midday in Mare Undarum, so the view is rather flat.  I am, however, happy at the appearance of Neper right on the limb.  Neper is at lunar longitude 84°.5 and the libration was tipping the Moon almost 2° the wrong way.
The scale markers are approximately 100 Km north and west and apply at Mare Undarum.
The picture was taken with a ToUcam attached to my LX200 on 5th June 2006 at 18:13 UT, when the Moon was 9.0 days old.
