Shortly after sunset I turned my telescope in the direction of the moon and was planning to sketch the crater Longomontanus. However that all changed when I spotted a ghostly, mostly buried crater in southern Oceanus Procellarum right at the terminator. For June 10, 2006 at C. Wood’s site - LPOD, you can find a photo of this region of the moon. Superimposed over this crater are a series of dorsa (ridges) known as Dorsa Euclides F. The lava in this region is not quite thick enough to cover all the evidence that this unnamed crater existed. To the east the 12 kilometer Copernican period crater surrounded by bright ejecta at the center of the sketch is Euclides. Just to the east of this crater are the Riphaeus mountains. North of the mountains you will see four of the Lansberg craters with the largest being Lansberg D (11 km.).
The two small Eratosthenian craters at the far left side of the sketch are Kuiper and Eppinger both at about 6 km. in size.
I love these views that inspire us to capture them with a sketch.
Sketching:
For this sketch I used: black Strathmore 400 Artagain paper 9”x12”, white and black Conte’ pastel pencils and a blending stump. After scanning, Brightness was decreased (-5) and contrast increased (+3) using Microsoft Office Picture Manager.
Telescope: 18 inch f/ 5 Dobsonian and 12 mm eyepiece 167x
Date: 8-12-2008, 1:35 – 3:05 UT
Temperature: 21° C (71° F)
Partly cloudy, hazy, calm
Seeing: Antoniadi II - III
Colongitude 35.8 °
Lunation 10.6 days
Illumination 78.9 %

Just an absolutely great sketch as well as a wonderful description of the sketch as well.
Very nice!

Rony, Tommy5 and Wade,
Thank you all for your positive comments on my sketch.  This is only an approximate sketch of the view. I would need more time and skill to render what the view was really like.

Frank,
An excellent observation of an interesting region of the Moon. The illuminated ridges appear to flow through the lunar landscape. Thank you for sharing it with us all.

Frank - great texture and detail. When I come over to the "dark side" of lunar sketching, I'll have your drawings to show the way.

Beautiful details in your rendering. Thanks for sharing.
I tried to sketch last night but cannot until my condition improves. I was seething at the bit to want to sketch so many beautiful terminator edge details. Once you start this process, it is a habit. So I just allowed the neighbors to observe through my scope. They had never seen the terminator at high magnification.
Keep up the great work as it inspires me!

Frank,
Great sketch--loads of detail. I find those dorsal ridges are hard to do and have them come out looking right--you did a good job on them. I like how the conte' makes the bright ejecta areas around craters look so realistic, too.

Phil and Michael,
Thank you for the kind words.
Michael, I have trouble sketching dorsa too. More experimenting and practice are in order.
Phil, I was a little nervous about posting sketches here among all the highly talented artists. There are many more that have not posted recently. They are all most inspiring to me.

Frank, after just looking at Rony's Lagoon and then this, I feel like I just had two big homemade deserts. Great sketch and good observing. Roland

Michelle,
This sketch gave me a little trouble because the scene was changing rapidly. Thank you for your kind words.
