Chalk-/charcoal sketch of Rupes Recta

[acr_astro]

Dear all,

today we had a wonderful sunny autumn day here in Western Germany with a cloudless sky tonight. So I set up the 10" truss tube Dobsonian on the terrace and enjoyed sketching Rupes Recta - the straight wall.

Telescope: Martini 10" f/5 truss-tube Dobsonian
Eyepiece: ExploreScientific 6.7mm/82°
Date & Time: November 23rd, 2020 / 1800-1900 CET
Location: home terrace, Dusseldorf region, Germany
Technique: Koh-i-Noor chalk, extra charcoal and whitecoal pens and pieces on black Hahnemühle Ingres mould-made pastel paper
Size: 24x31cm

Rupes Recta separates the Erathosthenian floor of Mare Nubium westwards from more rocky Imbrian surfaces east of it. The small crater directly west of it is the copernican crater Birt. The tiny one in its south east is the 4 mile craterlet Birt A. The larger one a bit more east of the "wall" is the Imbrian crather Thebit with a smaller copernican crater Thebit A on its rim.
Some words for the paper I have used: Normally I use this for pastel sketches. My pastels are a bit softer than chalk and charcoal and cover the paper a bit better. The chalk and charcoal require a bit more pressure to get it on the paper but when wiping it with my finger, the surface gets pretty smooth. Compared with my other black sketching paper, the texture of the mould-made paper is more prominent.

I need to get a bit more used to it...

Clear skies!

Very nice! It looks almost 3D popping out of the paper!

Lovely sketch, thanks for sharing.

Hi Achim,

You have captured the area well and so good to have sketched the other interesting craters near to Rupes Recta. Good idea to experiment with the paper - it adds texture.
