Riphaeus Mountains on Oceanus Procellarum
      #5411904 - 09/09/12 04:24 PM Attachment (41 downloads)

At midnight weather was not looking good for sketching as it was pouring rain. A few hours later the clouds moved on leaving marginal seeing and hoards of hungry mosquitoes.
The Moon and Jupiter were up in a clearing sky so sketching became a possibility. It has been a while since I have sketched barebones with copy paper and a number 2 pencil but that is what seemed right. Our atmosphere was interfering with a good look at Jupiter so I turned to the Moon, a target rich environment.
This sketch includes a region in southern Oceanus Procellarum adjacent to Mare Cognitum. Copernican era, bright crater Euclides formed the center feature along with the Riphaeus mountains. The ancient Raphaeus mountains are the rim remains of a large 225 km. crater mostly buried under dark lava today. Names included for the mountain arcs of Riphaeus were: the Urals; Boreus; Major; Minor and others that I learned some 50 years ago but those designations are officially gone. The soft landing sites of Surveyor 3 and Apollo 12 are just beyond the sketching region to the lower left.
Tomorrow morning at Moonrise this region will be on the terminator producing its best view of the month in my opinion. Domes and volcanic rises become visible under these low sun times.

Sketching:

For this sketch I used: white copy paper, a No 2 graphite pencil and a piece of tissue for blending. The sketch was photographed and cropped

Telescope: 13.1 inch f/ 5.9 Dobsonian and 4 mm eyepiece 491x, scope was driven on an equatorial platform
Dates: 09-09-2012, 09:40-11:00 UT
Temperature: 10 C (50 F)
mostly clear, calm
Seeing: Antoniadi III- IV
Colongitude: 192.7
Lunation: 22.75 days
Illumination: 42%

The sketch gives a very good feeling of the bright light in that area without sacrificing any detauils. Great!

Hello Frank,

I was wondering where your sketches were!
That pencil did a magic job in your hand, Frank.
Nice work and subtle shading.

Clear skies,

Uwe, Rony, Ian, Jef,

Thanks to you all for the kind words. This can be a fine time of year for clear steady nights in the northern hemisphere.

I think it's beautifully and accurately done! I do love the feel of graphite or charcoal lunar sketch.

Rutilus, Tom and Erika,

Thank you all for your kind comments.

Erika,
Over the past two years I have learned to take it easy with the graphite and not put it on so heavy as to make it shine. For this sketch I stayed away from the softer/ darker 4B and 6B graphite pencils. I think the charcoal looks better but I'm more comfortable and less messy with graphite. Your work with charcoal is as good as I have ever seen but you will have a hard time toping that M. Crisium lunar sketch (white on black paper). Everything came together for you in that sketch and I think the Moon wants to be sketched that way.

Frank
