Mare Humorum
Mare Humorum, “the sea of rain” is the home of magnificent crater Gassendi and some rather neat concentric circular ridges. As part of my effort to complete the Astroleague Lunar certificate I was checking off a few craters, in this case Gassendi and Agatharchides and thought it might make a neat webcam shot. The view was by coincidence close that of Rukl Chart #52.
Image taken late Saturday evening from Louisville, CO with Celestron Nexstar11 telescope and Phillips Toucam 840K webcam at cassegrain focus. Sky was mostly clear, temperature 60° F, turbulence 5/10, and no wind. Transparency was good even with high humidity.
