Aloha!

This was one of those nights things just fall together. Excellent seeing and light enough from the Moon that I could see the paper well. After finishing my sketch at the eyepiece I went inside to clean it up and was pleasantly surprised that I liked it pretty much the way it was.

110km wide Gassendi Crater showed some excellent roughened floor details with hummocks casting shadows as well as floor rilles illuminated as bright & dark lines. Rima Mersenius is brilliantly lit on the terminator and the bright scarp of Rupes Liebig can be seen at the base of the wall.

  1. Hello Cindy,

    This is a great looking sketch of Gassendi and its surroundings. Lots of attention to detail and beautiful execution really make this sketch.

  2. Aloha Cindy! Your sketches illuminate the details of the lunar features as I’ve never seen them. You’ve got a good eye and steady hand for sketching. Thanks for sharing. You are the best astro gal pal on the planet! –
