Stunning views of the Moon on Sept 4th

Hi all,

I couldn't see Mare Crisium with the unaided eye tonight so suspected a maximum libration has tipped it close to the lunar limb. The 10x50mm binos confirmed as much.

But it's the rest of the Moon on view this evening that is stunning even in these grab-and-go instruments.

Sinus Iridium is right on the terminator and I can see the higher ramparts of Montes Jura illuminated by sunrise while the Bay itself is still somewhat in darkness.

The ray from Tycho that stretches across Mare Serenitatis is nicely defined while there's alternating light and dark streaks splayed towards Mare Nectaris and Fecunditatis. The mind's eye pictured the southern highlands as the bulbous head of some creature giving the whole scene the impression of a giant octopus occupying the SE quadrant of the Moon.

I think it is the crater Clavius Gassendi which is also catching the first rays of lunar sunrise at this time too. The 10x magnification and now clouded over Moon cut short my attempt to make certain the identification. Edited to correct the name of the crater observed.

All in all, just a 15 minute glimpse of lovely luna but hopefully a taster of what wonders you can see in just a few minutes with simple equipment.

Great to see you doing some observing with your 10x50 binoculars, John.

Paul Byrne and myself both love Sinus Iridum and the Montes Jura. Please do check out my adjoining report regarding Rupes Recta. It certainly is a great time observing the Moon at the moment.

Aubrey.

Not long in from work and dug out the binos. Sinus Iridum is very prominent, looking like it is standing above the Lunar surface. Kepler and Gassendi are appearing into daylight looking wonderful. The woman in the moon is very obvious.

I conducted an experiment some years back about the smallest object I could see at full moon with tripod mounted 10x50s and it was a crater ten kilometres across, I cant remember the name. I must do it again at a different phase.

A quick scan of the skies revealed the Coathanger, Albireo and the Double Cluster, I must use the binos a little more.

I was hoping for a good sky on Weds night, but as is often the way. the clouds rolled in just before darkness. I did however manage to get this snap of the daytime Moon, quite low in the South, this taken at 19:30 local time...

That's a lovely shot Paul with the Moon offset by the cool blue colors of evening twilight. Many thanks for sharing.

I never thought of looking for the smallest feature visible in 10x50mm binoculars but must try it some time. It's amazing how much detail can be revealed and mounting the binoculars on a tripod as you suggest Paul makes all the difference.

Thanks Aubrey for sharing the report of seeing Birt E and Rupes Recta. Michael Grehan gave me a long-term loan of an 8-inch Dobsonian and once I refurbish it the Moon will be top o' the list for first light.

I checked www.calsky.com and found the 2nd greatest lunar libration of 2014 occurred at 9h (UT) on Wednesday, September 3rd (almost 9 degrees). It tipped the southwestern limb more into view which is why Mare Crisium was not as obvious to the unaided eye.

I've corrected the name of the crater I saw ... It was Gassendi and not Clavius. There's a nice index for each lunar day at www.stargazing.net/david/moon/index29days.html ... click on the image for each day and you'll find some of them link to another picture with labels. Very nice!
