A very interesting area to view with good seeing conditions, which I had this evening.   This is also a much sketched area, but I figure I'll add mine to this list.  Couldn't help myself...the seeing was so good! There is still some mystery as to the origins of these rilles and they may not be graben.

Thanks for taking a peek,

Regards and clear skies,

Randolph

Hi Randolph,

this is a wonderful sketch! I like the three dimensional appearance and the different tones of the surface!

So nice, what a good technic you have Randolph!  I feel your technic similar to this one of Jef.

Bravo!

Randolph,

 

Your skills are simply unfair! I honestly thought I was looking at a mobile phone shot through an eyepiece when I initially glanced at your drawing. The rilles just POP!

Great sketch, I thought it was a photo at first.  What is a graben?

Utterly outstanding,Randolph! I am in awe of your rendering of the rilles and Marium surface northeast of Triesnecker! waytogo.gif Telescope.gif

Randolph,

 

Absolutely a top notch capture of this region. The lighting conditions here are perfect for sketching the rilles. You captured rilles V and VII very nicely.

A wonderful capture suitable for framing.

Thank you so much Achim, Jens, Michel, Codbear, Mike, AstronZ, and Frank.  Mike a graben is an area of crust that lies between two faults that has dropped downward relative to the land on either side.  I believe that the Alpine Valley is a good example of a Graben as is the Rima Hyginus.  There is a real mystery as to how these rilles near crater Triesnecker formed.

Regards all and clear skies!!  I have never seen this rille system as clearly as I did last night, thanks to the very good seeing conditions.

Randolph

Thank you Jef.  Randolph does not "master it much better" than you.  Your sketches are superb.  But I suspect we use the same or similar tools in executing a lunar sketch.  I used white and black Conte pencils, a white Faber-Castel pastel pencil for some areas that are very bright, some pastel dust, liberal use of blending stumps and all done on black Artagain sketch paper.  I've tried other sketch paper, but I've found the "tooth" on this paper works well for blending.

Regards,

Randolph

WOW Randolph, i'm in awe!

My first thought was "it's like a photo!" but no way! There's no photos like this. As Jens said, BETTER than a photo. Congratulations and thanks for sharing

Many thanks Alfonso, Paul, Pedro!  I really enjoyed seeing this area with good seeing, and it was very satisfying to sketch this as well.

Regards and clear skies,
