Cleomedes Enters Shadow
#5549753 - 12/02/12 02:30 AM Attachment (39 downloads)

Just north of Mare Crisium and formed during the Nectarian period is the 128 km. walled plain crater Cleomedes. This crater has a high but worn margin and was nicely catching the last rays of sunlight overnight. Selenologists believe the floor may have been flooded by lava that reached the crater through fractures from the molten lava of Mare Crisium. What remains of the central peak is a low wall oriented north-south and somewhat off center. A hint of 60 km. long Rima Cleomedes was just detectable north of the central wall running off to the southeast. To the northwest of Cleomedes is 57 km. crater Burckhardt straddled by its close partners E and F (both deep in shadow). Off to the northwest is crater Tralles (43 km.) hugging the rim and on the floor of Cleomedes are small craters J and B seen near the central wall.

Sketching:
For this sketch I used: black Strathmore 400 Artagain paper, white and black Conte’
pastel pencils. In addition a small artist’s brush and powdered Conte’ white crayon was used for blending. Contrast was slightly increased (+2) using a scanner to better match the original.

This is great. I need to try and sketch a crater one of these days.

Frank, I am in awe of your lunar sketches. You pull them off so nicely. Having tried it, I have some idea of how difficult they can be. I am sure it's enjoyable work and you make it look easy.

I wish I could pull down those beautiful views of the moon. Unless it's Plato or Sabine, I usually have no idea where I am looking. Just admiring it, anyway.

Mike, Norme and Jef,

Thank you all, I have sketched Cleomedes in the past but this was a view in great lighting.

That is another great lunar sketch. I find it impossible to draw any substantial lunar detail right at the terminator,with the light changing so rapidly.I usually cant get one simple crater done.I also like your choice of Pastel on black paper.

Jim,

You can do this. You must decide before you start drawing if you are going to do the terminator first or last. Sometimes my terminator features are impossible views because one part is 45 minutes different from another. I try not to let that happen. You will gain confidence by doing practice sketches for speed. You need to know in advance how long it takes you to sketch a feature. On some sketches I have completely erased a crater on the terminator because it looked better later during the sketch.
Start small- do simple smaller crater first. Get the shape and the shadows and the rest will gradually come along.
Sketching the Moon is very satisfying.

Frank, you are a lunar freak. Your perseverance and deliberation must be akin to a wild cat during the hunt. I am mesmerized by the degree of detail available, here. Cleomedes is gorgeous...I love the contrast of the smaller craters tops within as they "pop" into the landscape. But I am unduly frightened by the fractured landscape to the upper left of the crater. Your work is inspiring me to give the lunar surface another trial. Brilliant sketch.

Uwe and Jason,

Thank you so much for your kind words.

Uwe, I'm waiting for your next close in lunar sketch.

Jason, you take a backseat to no one. Your recent sketch of the Moon, Jupiter and the Barn is a real eyecatcher; it is very pleasing to the eyes.

Frank,

Quite nice. I see why you wanted to do Cleomedes at this time in the lunar cycle--the scene has very dramatic lighting. And isn't this the crater that looks like Mickey Mouse when the Moon is waxing? It goes from drama to cartoon.

Jason, Frank isn't just a lunar freak--he's one of the co-authors of Sketching the Moon An Astronomical Artist's Guide . [Hint: his nom de internet rhymes with McCague]

Lunar sketching is daunting. Frank and his co-authors take away the fear with this wonderful how-to book.

Jason,

Your sketching is excellent.
Oh, and Michael Rosolina has a couple of sketches in our book too. Here is one posted at Lunar Photo of the Day,

Michael,

Thank you for the book plug and the comments on this lunar sketch.

There is a crater group on Mercury that look like Mickey Mouse but I don't know about Cleomedes on the Moon, I'll need to check that out.

Frank,

It's just Mickey's head and ears. Either Tralles, Debe, and Debe A or Burckhardt, Tralles/Debe, and Cleomedes. They probably know over in the Lunie Bin.

Sally did a great job putting that composite together--what fun!

I wasn't aware of Mickey on Mercury--that mouse sure gets around.

I'm not real hip on the various locations on the moon, but those little craters in the big crater have a definite 3d effect to them. They're kind of OUTSTANDING, if you know what I mean.

Glad you're the one doing this, Frank, because this type of sketching would certainly drive me bonkers.

Thank you for you comments on my sketch of Cleomedes.
It was a fine night to be out sketching this time of year.
