Before sundown clouds departed to expose a 7 day old waxing crescent Moon high in the western sky.
From top (South) to bottom (North) are craters Lade (58 km.), Godin (36 km.) and Agrippa (48 km.). This region was at the terminator and striking to observe on this occasion.
Crater Lade with the missing south wall and the large lava flooded floor dates from a time before any life is known to have existed on earth. Crater Agrippa appears on the Moon sometime between the oldest cyanobacteria microfossils and the appearance of the first multicellular eukaryotic metazoans life forms. Godin is younger still, a Copernican period impact. All three of these craters are in a rugged lunar terrain well west of Mare Tranquillitatis and just south of Rima Ariadaeus showing well in the low morning sunlight.
Sketching:
For this sketch I used: black Canson paper, white and black Conte’
pastel pencils and blending stumps, white Pearl eraser
Telescope: 10 inch f/ 5.7 Dobsonian and 6 mm eyepiece 241x

Date: 05-17-2013, 01:10 - 02:40 UT
Temperature: 16° C (60° F)
Partly cloudy, light breeze
Seeing: Antoniadi III
Colongitude: 353 °
Lunation: 7 days
Illumination: 38.8 %

Lovely, Frank. The shadows are truly wonderful and give the whole a very realistic touch. Love it!

Frank,
Great work. I love the shading and dimension. I especially enjoy the ridge lines. You almost feel like we are landing soon.

Christian, Peter and Ken,

Thank you for your comments.
The seeing wasn't the best and most of the interesting rille features were in shadow beyond the terminator. I was interested in catching the craters in deep shadow here. Caught my eye at low power.

Frank :)

Hmmm. Frank, did this sketch hurt to do it? It seems to have so much energy in it. Bold, detailed, uncompromising. It looks like you were dealing with a beast and wrestling it by the horns. A bit out of the ordinary from what I'm accustomed from you, but mate, I love it! Looks like you got a bashing!

Alex.

Alex,

Thanks, when I finished I said to myself - "Did I over work it?" I think the answer is yes. I should have just sketched the craters in the middle. I found myself racing to finish.
