The Modified Crater Heraclitus
      #5437403 - 09/24/12 02:59 AM Attachment (29 downloads)

The southern lunar highlands expose the ancient anorthositic crust between craters. Centered in this southern highland sketch is the buried pre-Imbrian crater Heraclitus (92 km.) with its unusual central mountain crest. This ridge or crest looks much like the one on the floor of the elongated crater Schiller formed during its shallow angle impact. The ends of Heraclitus are buried under Licetus (77 km.) to the north and Heraclitus D (52 km.) to the south. Its easy to imagine this possible Schiller twin here partly hidden. To the east is crater Cuvier (76 km.) with its smooth floor and western wall pressing in on Heraclitus.

Sketching:

For this sketch I used: black Canson paper 9"x 12", white and black Conte’ pastel pencils and blending stumps. The scanned sketch is unmodified

Telescope: 10 inch f/ 5.7 Dobsonian and 4 mm eyepiece 362x
Date: 09-24-2012, 00:15 - 01:50 UT
Temperature: 10°C (50° F)
clear, calm
Seeing: average Antoniadi III
Colongitude 11.3 °
Lunation 7.9 days
Illumination: 63.5 %

Frank, your talent is apparent. Well done, you bring the beauty of the moon to life. That's hard to do, but not for you..apparently.

Jef, Norme, and Ian,

Thanks for you kind feedback.
On the evening before this sketch I attempted to capture this region with a much lower sun leaving the central ridge looking like an illuminated rectangle. Clouds ended that session very early.

Mel, Eric, Tom and Uwe,

Thank you all. There are a lot of interesing craters in the southern highlands.
I always feel a strong urge to get out and sketch before the very cold cloudy weather arrives.

Well consider it now commented!

It is a very fine and detailed piece of work. I like it a lot!

Hello Frank,

Nice to see that you spend some time behind the eyepiece!
I like how you managed to accurately render the range of gray tones of the moon's surface. Masterly, Frank!

Rony,

Thank you much my friend. I try and get out every clear night.
I have enjoyed on several occasions recently matching the views with your sketches in the book "The Casual Observer's Guide", Your book and sketches are inspirational.

Frank
