More of the Southern Highlands
I have always found the southern highlands an interesting region of the moon to examine along the terminator. At the times of low sun the craters here take on more unique and individual identities than at higher illumination. On this observing and sketching night, I managed to examine and sketch five notable craters. From south to north along the terminator are Boguslawsky (98km.), crater Boussingault E ( 98km.) and Boussingault B (54km.). All over the southern highlands are numerous, ancient, worn, soft looking craters between 10 and 90 kilometers in diameter. Some of the craters in this region pre-date the formation of the major lunar basins. These craters look soft and dusty with smooth terraces and regolith slumping to the crater floors. Lunar geologist Donald Wilhelms speculated that the appearance of the craters here is caused mostly by fluidized ejecta and debris tumbling down the crater walls to the floor. He also believes that the craters in the region of the sketch are sitting on an ancient 650 kilometer basin that is all but destroyed save for pieces of rim here and there. The two craters further west from the terminator from south to north are Manzinus (98 km.) and Mutus (78 km.). Craters B and A, both about 16 km. in size, can be seen on the floor of Mutus.
As a target the moon proved to be a very enjoyable subject on this evening of observation and sketching.
Sketching:
For this sketch I used: black Strathmore 400 Artagain paper 10”x 8.5”, white and black Conte’ pastel pencils and a blending stump. After scanning, Brightness was decreased (-2) and contrast increased (+2) using Microsoft Office Picture Manager.
Telescope: 10 inch f/ 5.7 Dobsonian and 9 mm eyepiece 161x
Date: 9-18-2008, 4:05 - 5:30 UT
Temperature: 15° C (60° F)
clear, calm
Seeing: Antoniadi III
Colongitude 129.5 °
Lunation 18.4 days
Illumination 90 %

Frank,
You know, the wife and I did not do any observing tonight, instead we opted to "vegetate" around the TV and surfing the net for the evening.
But after looking at this sketch, in a way we did observe the Southern Highlands this evening! As always, an excellent sketch that captures the finer nuances of this Lunar region.

Wade,
Thank you for the nice thoughts.
No observing here either right now. Earlier in the evening we had a viewing for the public at the community college where I work. It didn't last long before the clouds won the night.

Very nice Frank, as always.
I have this image in mind, that some day you will have a giant, composite mosaic sketch of the entire surface of the moon, covering a wall of your living room.

You are right, Frank, the area is interesting and especially (to me) with a waning moon. There is something about the shadows--maybe because they seem less familiar or they deliver increasing contrast during a 2 hour period or so--that makes sketching during the last half of the cycle very nice. Good sketch. Roland

Frank,
A wonderful and accurate observation and report of the lunar southern highlands. You have recorded this region of the Moon very nicely. Thank you for sharing it with us all.

Beautiful sketchwork as always from you. As clouds may clear here tonight, you have me inspired to get out there and drag some chalk over the paper again.
Thanks for sharing this,
Mark

Tom, Roland, Carlos and Mark,
Thank you all very much. As the cooler air of fall approaches may you all have great success observing and sketching and just in general taking in the vast heavenly firmament.

Yes Frank, you read my mind! My comments were some light-hearted banter arising out of admiration for the way you fearlessly tackle such complicated terrain. (Is "terrain" the right word?)
In any case, I'm enjoying your contributions.

Great sketch Frank, i had planned to visit the college last night, but it looked like heavy overcast was rolling in, it cleared up later at night as i saw the moon near the Pleiades friday night, anyway great sketch, thanks for posting.

Tommy5,
Thank you.
You did not miss much Friday night, everyone there got a look at Jupiter and its moons and then the clouds quickly shut us down. The mosquitoes were there too.

I like the mosaic. Can I order one today? (; Only Problem is, I just lost my home in foreclosure that I designed and built after 20 years with tall vaulted ceilings and have nowhere to hang the art now. Not to ramble off topic here aside from artistic sketching but I hope to hear as much from others as possible about advice to rebuild again as the bank is throwing $100,000 at me to compensate the loss. 20 years ago I built the home for $54,000, the edge of city lot was $9,999 and all inclusive in that 54 G figure! That 80' X 100' lot is now worth $85,000 empty (see my home
on it in as a curent all inclusive value of $250,000) > upper right column front page > www.myspace.com/marksolarprophet
I will begin with the payoff to a road trip travel starting soon across the continent as I did in 2000 but more so looking for possible lecture venues to show my astronomy art. Also looking for any advice to do this for science institutions or schools. I have had many suggestions but it may be difficult to arrange on such short notice.
I look forward to any advice from anyone before the travel weather ends.
Thanks,
Mark

Sorry for your troubles but this has ABSOLUTELY nothing to do with this forum or sketching in the least.

Frank,
After reading the response by Michelle D. above, it has occurred to me that quite often I will comment on your fantastic sketches, but forget to make note of the excellent descriptive write-ups that accompany them.
I just want to let you know that I do enjoy the articulate and informative descriptions you give with your sketches. Keep it up!

Frank,
Yet another exciting sketch from your hand!  
I'm amazed by how well you turn a sheet of black paper into a distinct moonscape with plenty of details.
The terrain looks very dramatic in your sketch. The curvature of the surface is very well represented, it gives the sketch a realistc 3D look.
The mosaic is a nice idea! 
Frank, how large would such a mosaic be?
A little funny sidenote : It struck me that you refer to distances on the moon in km's, while I thought that the 'mile' is still very popular in the US of A? Or is there a change of mind going on?

Michelle, Wade and Rony:
Thank you all for your kind words.
------
Rony,
I'll do a mosiac when you make one of the entire celestial hemisphere with those beautiful binocular sketches.
I can remember in the 1960's telling my students we would be soon changing to the metric system. It has not happened yet---I can't believe it!! As soon as I get a frame and get to the post office I'll P.M. you.
Frank

Frank, I also enjoy the background that you provide along with your fantastic sketches. Being relatively new to the hobby when I view an object I always like to look up any interesting information/background on that object and try to include that in my log for future reference. So thanks for not only providing some great visuals but also some continuing education along the way  .
