Eratosthenes, Stadius & spur of Montes Apenninus
      #5692173 - 02/21/13 04:28 AM Attachment (48 downloads)

Here’s my first lunar sketch since August last year.

This particular sketch has been most rewarding. Not only was a seemingly “featureless” lunarscape most detailed, but the subsequent research I did on this area opened my eyes to lunar geography that I was totally ignorant of. A most enlightening last couple of days it’s been.

One feature I hadn’t sketched before was a submerged crater. Stadius is a very ancient crater that has been flooded by lava, either that poured over from the surrounding Mare, or had been filled from below. Either way, its floor is level with the surrounding plain and the central peak covered.

Erastosthenes makes for a striking ‘full stop’ to the western spur of the Apenninus mountain range. The spur and crater are surrounded by flooded Mare which at first appear to be featureless. Yet these plains a pot marked with tiny craters and the flood plains are laced with subtle colour variation of light and dark, giving an insight to the mix of flows and compositions.

A surprising feature for me though was a wavy chain of craters that lies between these two craters and a little further west. When I started to research this chain, I came to find that it is actually a line of secondary impacts created from the ejecta from the impact formation of the crater Copernicus! This line of craters was the last feature that I sketched last, but conditions had deteriorated that prevented detailed examination.

This was a very satisfying sketch. From not initially seeing much detail or features turned into a great sketching exercise and a fascinating research project.

I hope you enjoy this sketch too.

Alex.

Its the shadow detail that makes the real standout lunar sketches IMO and this sketch really shows the depth that those shadows create, I'II keep watching and learning Alex!

Beautiful, what a wealth of details. Like the "natural flow" of your sketching technique as well!

Wow! What a fantastic sketch!!! The way you draw the shadows and illuminated parts looks like the real thing indeed. My sincere admiration!

Alex,

Your first lunar sketches on black paper were fantastic, but this one is above and beyond all of them. Totally impressive.

Thank you all for you kind comments.

For those who would like to learn more about the Lunar geography, there is a very good site "Observing Along the Moon's Terminator". The link takes you to the page where the secondary impacts of Copernicus are mentioned. The six pages that the site is, is a wealth of information of lunar formations. It not only points out features on the Moon, but makes direct comparisions with Earth geography.

If I keep looking at your moon images Alex I might even be inspired enough to have a go at a crater or two one of these nights. For some reason I find the moon a little intimidating ... maybe I'll have to get a list of 'easy moon targets for beginners'. You've certainly got the technique nailed.

Youve got a nice command of light shadow and form. Wonderfully done.

Real great, phantastic sketch. Erastothenes is among the hardest to sketch areas because of the wealth of detail.

That's a pretty detailed work, Alex! Love that blue tone in it. Better that a photo, to my point of view.

Well done Alex, the mountain range is terrific & is not often sketched
