Aristarchus, Prinz and the Harbinger Mtn. Region
      #5933500 - 06/21/13 06:45 PM Attachment (30 downloads)

The kilometer high rim of Prinz (47 km.) crater was casting a shadow across its own lava flooded floor. The uplifted Harbinger mountains were also casting fine shadows in this region of the lunar surface with its large magma ponds pushing up and freezing in the distant past. The uplifting doming in the region created many fissures for lava escape and flooding to occur. The fissures can be seen clearly on nights of steading seeing. I was denied that detailed view on this night. From the crater Krieger (22 km.) north and somewhat east of Aristarchus (40 km.) four distinct long shadows could be seen crossing to the 70 km. fault called Toscanelli at the edge of the Aristarchus plateau where the terminator was located during the rendering of this sketch.
A fine view in any telescope.

For this sketch I used: black Canson paper, white and black Conte’

Date: 06-20-2013, 02:40 - 04:10 UT

Cool sketch, I like how the Aristarchus region changes as the sun climbs higher in the lunar sky, great shadow work as usual.

I really like the 4 long shadows you captured near the terminator. Great sketch. The ridges in the center resemble someone with bad handwriting. Looks like a i,S, and a backward R.

Hey Frank. I observed the moon at the same time of you. I was really captivated by theses special long shadows you got on your sketch. Simply beautiful sketch Frank, really.

Christian and Pete,

Thank you both for your nice words. Long shadows and other unusual features near the terminator are always a treat.

Oh wow! You have a somewhat abstract style which really makes your drawings a quite personal impression rather than just trying to copy what you see. Very nice, Frank!
