Mare Imbrium Under First Quarter Light

Here is a composite view (two areas of the moon photographed separately and then merged into a single panorama) of Mare Imbrium during the first quarter moon on the night of November 7, 2016.  The moon was 52% illuminated, making the craters and other features really stand out in this area.

Craters Wilhelm, Longomontanus and Clavius

Time to learn some moon craters! I present Wilhelm, Longomontanus and Clavius.

Wilhelm – diameter is just over 100 km, named after Wilhelm IV (Landgrave of Hesse), German astronomer (1532-1592).

Longomontanus – diameter is just over 145 km, named for Christen Sørensen Longomontanus; Danish astronomer and mathematician (1562-1647).

Clavius – diameter is just under 231 km, named for Christopher Klau (Clavius); German mathematician (1537-1612).

For me, Clavius will always be associated with the movie 2001: A Space Odyssey. The information above was taken from the International Astronomical Union (IAU) Gazatteer of Planetary Nomenclature that can be accessed at: http://planetarynames.wr.usgs.gov/

Tech Specs: Canon 6D, Meade 12” LX90 telescope, best 300 frames out of 1,500 frames using the software package Registax.

Region of the moon where these craters can be found.
