An Alpine dawn & a craggie terminator

Hi all,

Here are my two latest sketches. The first one was done on Sunday night. I thought I was sketching the Alpine Valley as the main features so much resembled the deep trench of the Alpine. Monday night I had hoped to do a second sketch of the same feature, showing a successive sequence of night's terminator creep. Boy, did I get a surprise.

Both sketches where done with the same gear from my home:
Scope: Celestron C5
EP: TMB Planetary Type II 6mm, 200X
Media: Pencil, paint and ink on white paper

So, the first one: "The craggie terminator", around the crater Julius Caesar. It is bound to the east by a mountain ridge which at the time of the sketch, the terminator gave the impression of this ridge actually being a rift or valley

The second: "An Alpine dawn", the area around the Alpine valley as the sun rises over the massive rift. The crater Cassini A lies immediately to the left of the dawn lit Alpine Valley. The craters Exodus & Aristoteles (left to right) lie above the pointing Valley.
