Crater Langrenus

by Vern on Aug.11, 2006, under Astronomy, Lunar

Lunar crater Langrenus is an awesome sight in a good scope when the air is steady and lots of power can be used. A couple high central peaks can be seen in the below image as well as a number of its terraced walls.

Image taken at 08:39 UT from my backyard in Louisville, CO, with Celestron Nexstar11 telescope and Phillips Toucam 840K webcam. 100 seconds of video, 1/32 sec shutter, 15 fps, 75% brightness, and 30% gain. The sky was clear, temperature 64°F, turbulence 7/10, 50% humidity, and transparency excellent.

    Those are great shots the detail is really impressive. Looks like you about to land.

    Thanks Brian!

    View through a scope at high power on a night with steady air comes pretty close — at least in ones imagination.

    Awesome shots…

    is it possible to shoot where the Apollo missions landed AND is it possible to see the stuff left behind?

    Landing sites of various USA Apollo and Soviet landing sites are available. Pick up a copy of the \”Field Map of the Moon\” by Sky and Telescope Magazine, the landing sites are marked. I imagine they are online as well. Not possible to see any of the stuff left behind from scopes here on earth, though maybe some of the future lunar orbiters may be able to.
