Thank you Eric!
I'm throughly enjoying your afocal captures! Beautifully done. The seeing has been pretty lousy the last couple of days, hasn't it? I find my self chasing focus during the entire session.

Thanks Carol, 
So Montes Jura must have been a spectacular view, I was amazed by the bright ring standing out in the dark, like loose from the terminator, this must have been a spectacular view in my scope. I think I'm hooked to our nearest neighbour, it's a very interesting and varying object, there are soo many areas to observe, it might even take a lifetime and still things to be seen after that!
Regards,

Yes, they're very impressive and I hope you're able to see them through your scope soon. Three years ago I saw the mountain chain emerge peak by peak out of the darkness and it was quite a sight. After the entire chain was illuminated, it just hung out there in the blackness of space. Very beautiful!

Last night the atmosphere seemed calm enough to attempt a sketch. A little cluster of hills west of Gassendi captured my attention, so that was my target. When sketching the moon I often sketch first and identify later, but this time I ran into a problem. This feature is not labeled on any of my charts (including Rukl's). These hills are located near the center of a diamond formed by Gassendi, Mersenius, Billy, and Letronne. If anyone knows of a proper name for this feature, please let me know!

Sorry to be a day late in getting these up. Here are my photos an report for my session last night. It went back to fog and clouds just a couple hours after I got these and looks like I'll be shut out for a bit...
Moon Tour along the terminator. Waxing gibbous, 1 Dec 06, 2030-2200L (1930-2100 UTC). Orion 127mm StarMax Mak-Cas with an NX Vega 3000 webcam. Seeing 4/5. Desenzano del Garda, Italy.
Yesterday’s sunrise on the Jura Mountains has given way to full illumination on Sinus Iridium. The “Moon Maiden” in Cape Heraclides (a mermaid if you include crater Bianchini as the tail flukes) lounges on the shore of Mare Imbrium as a series of shallow waves undulates across the mare floor towards her. On the terminator behind her, craters Harpalus and Mairan have just emerged into daylight although their floors remain shadowed. Herpalus shows an interesting double margin with a roll of material running around the outside below a sharp rim. Although the libration is unfavorable, crater Carpenter is peaking up into the sun on the lunar limb.
Southward of the Maiden, waves continue to roll in on the shores of Imbrium, having passed between crater Gruithuisen and Montes Harbinger. Like Herpalus, Aristarchus is emerging and shows a double rim on the sunward edge. West of Kepler and Encke lie a pair of partially buried craters, flooded with mare lavas from the southwest. Still further southwest lies a crater almost completely erased, filled with mare lava until just a few scattered tips of its rim remain, revealing themselves in the extreme low sun of lunar dawn. In contrast to this ghostly remnant, crater Flamsteed punctuates its southern rim with a sharp young appearance. Immediately southward from Flamsteed, perhaps five or more flooded craters reveal themselves in the morning light.
Standing in sharp contrast to these subtle features, Gassendi and Gassendi A and B jump out. Within Gassendi, the central peak appears to have not just one summit but three forming a compact arc. Jutting from the southwest edge of Gassendi into Mare Humorum is a bright wedge, part of a concentric system of rings encircling the floor of Mare Humorum. These cracks give the appearance of a collapsed floor to the mare as the underlying lavas erupted, similar to giant caldera eruptions on Earth. Southeast of Mare Humorum, a trio of rilles follows the southeastern shape of the mare basin cutting between craters Campanus and Hippalus but then curving northeast.
Below Humorum, a pair of prominent overlapping craters appear. Hainzel shows a distinct “peanut” shape with the appearance of a central peak in each lobe of the crater. In contrast, the larger Schiller shows only one peak on the northern portion while the southern half shows a clean smooth floor. The surrounding terrain is heavily cratered with a hodgepodge of young, old, large and small craters. To the southeast, Clavius delights the casual viewer. An old appearing crater with battered walls, Clavius contains several younger impacts within its bowl. Rutherford lies at the head of a chain of five craters almost equally spaced and uniformly descending in size as they arc gracefully across the floor of Clavius. Porter mirrors Rutherford on the opposite wall. At least 15 other tiny craters lie scattered across the floor.

Eric, superb sketch, those hills are the Montes Graff!
Seriously though, I can't seem to locate a name.
Steve, great report, terminator mosiac and associated enlargements. Wonderfully written observational prose poem of your terminator Moon Tour.
Hope you guys forgive me as well for my late entries. This one was done Thursday Night. I've got a bunch of avi's yet to process, but haven't had the time to process them. The seeing broke down after the sketch, so again the quality may be far from acceptable. Between observing and sketching and now imaging, then putting together a report, I don't seem to be keeping pace with the thread. (I've got another sketch and area mosiac I'm working on from last evening that I won't be able to post until tomorrow).
Lunation 1038: Day 10.31 November 30, 2006
Delisle, Diophantus and the Montes Harbinger
In the region of the great strait separating Oceanus Procellarum and Mare Imbrium lie two small Erathosthenian craters, 26 km Delisle and 19 km Diophantus. North is at the top in my sketch, and a view to the west (left) shows the two major peaks of Montes Harbinger shining out like two beacons in the darkness, brightly lit by the glancing morning rays of the Sun. Their lofty summits, reaching some 2500 meters above the mare floor, dominate the night side when the terminator crosses this region. The subdued, sinuous form of wrinkle ridges close by seems a quiet counterpoint this blazing spectacle. The Montes Harbinger are the visible remnants of the basin rim of Imbrium that existed in this area before mare lava flows inundated the terrain creating this wonderful gulf. Immediately to the southwest of Delisle is what appears to be a partial rim of a crater, Mons Delisle is listed in the VMA as an feature of unknown height. Judging by my sketch, I'd guess the peak to be roughly the height of the rim of Delisle. The set of hills with a odd triangular form about 65 km to the northwest of Delisle appear associated with a junction between three crater rims, now only the highest ramparts protrude from the somber mare.
These are the sketch details:

December 03, 2006: 3:20-3:50am UT Day 12 of the current lunation (1038). Sky mostly clear all evening. Air temperature is -9C (15 F).Seeing: Antoniadi III. Instrument:10in. f/5.7 Dob. 9mm ortho.eyepiece (161X) Moon is 95.4% illuminated with colongitude of 63.1 degrees. Target area 60 degrees west 12 degrees south.
Twin craters Sirsalis and Sirsalis A
The unbroken DNA lineage of life on earth dates back just a little further than the splash down that created Sirsalis A 1.5 to 3.2 billion years ago. The younger twin Sirsalis appeared just a bit later.Both craters are about 45 km. in diameter with Sirsalis A slightly larger.Both craters have 3 km high walls and the eastern wall of Sirsalis and the western wall of Sirsalis A are bathed in sunrise photons. The eastern wall of Sirsalis seems to be higher than the western wall and central peak which remain in darkness.J and F are the 2km. craters near the rim altitude of south Sirsalis. Rimae Sirsalis just visible in the sketch probably is a collapsed lava tube. It is seen crossing east of Sirsalis from NNE to SSW but meanders up and down the highlands beyond the area illustrated. This interesting region has been under study the last two decades for a magnetic anomaly.

Rich, Great report. As for the sketch, those Delisle mountain and crater shadows are really something.Was the seeing good enough at times to see little crater Louise in that light region S. of Delisle or the Diophantus rille?  Frank

Thanks all for the kind words. We had pretty good seeing on Friday night and I think some of my frames show craters down in the 2-3km size range (particularly inside Clavius). Not shabby for a 5" scope!
kraterkid, I love your sketches, particularly the striking contrast between the crater rims and floors. You really capture the 3-D aspect well.
vikingcraftsman, looks like you've caught craters Schickard and Phocylides (larger and smaller prominant craters on the terminator at about 45 degrees counterclockwise from top) just as they've come into daylight. From the bottom right corner clockwise you show Mare Nubium, Mare Humorum, and the edge of Oceanus Procellarum. If you have manual settings on your camera, you might try playing with your exposure controls and bracket what your camera thinks is the best auto setting. When in doubt, it's often easier to tweak a darker photo to make it lighter than get detail from overexposed shots.
