Dear Doctor Philips *[I am re-submitting this image today, a large 22" X 30" pastel sketch that was completed over the past month and just added an enhanced foreground to the art. I had a professional photographer friend re-photograph the work today to show finer details. I imagined that it might be posted to encourage others to observe the moons terminator line just before full or lust after full phase for this special large perigee moon.] Description: I observed the moon on February 15, 2011 through my Celestron Nexstar 5i telescope while showing patrons at a local restaurant deck which had never observed through a telescope before and repeated this again tonight March 17 2011 exactly one month into the same phase just before full. The terminator displayed an amazing lighting effect at Grimaldi Basin Crater. A blue box of light with an embedded shadow like a black arrow pointing into the darkness away from the sunrise on the surface of the moon. As I did not carry my art materials, after making brief notes and a preliminary sketch with fountain pen, and also made a few photographs through the telescope with my Sony Alpha NEX5 digital camera through a 9.7mm Plossl eyepiece of the Grimaldi Basin region for reference, I returned home to start a large pastel sketch on black Stonehenge 100% cotton pastel paper. The close-up of the terminator at mid page is from that technically accurate observation. The gibbous moon above was rendered from naked eye observation of the rising moon observed earlier in the evening in a golden hue. An artist’ conception as if from standing on the surface of the moon was roughly rendered in at bottom with a future possible lunar landing in the new Altair Lunar Lander. I recommend that others with telescopes take a look at the terminator line before or after full phase and witness the beautiful effects of shadow and light in stark relief.
