Lunar North Polar Region
For several nights this week the lunar North Pole has been tilted more towards earth due to favorable lunar libration in latitude. It has been a good opportunity to view craters such as Whipple, Peary, Byrd and others. I had a clear night with average seeing so I took advantage of the opportunity to sketch the illuminated region near the pole. At my location the Moon was at more than 60 degrees above the horizon which also helped with the time needed to complete a sketch.
Sketching and Equipment:
For this sketch, I used black Strathmore 400 Artagain paper 9” x 12”, white and
black Conte’ pastel pencils and blending stumps.
