    These three photos are snapshots of a video.Vignetting is visible on the edge of the images but I did not cut it because for not losing some regions.
       Today I will analyze the second image, and I'll write something about Kepler crater (32 km) from the center of the photo.
       Kepler is a crater that lies between Oceanus Procellarum and Mare Insularum west to the east. In the southeast is the crater Encke (in a photo 1 is to the east, in photo 2 is on the west by Kepler).
       Kepler is most notable for the prominent ray system. The rays spread around over a distance of 300 kilometers, which overlap with other craters.One of Tycho's rays that extends on the Oceanus Procellarum, intersects with Kepler.
       Other craters that are visible in photo 2: Marius crater (41 km.)-one with a perfectly round shape north of Kepler (and Marius A under him), Reiner (30 km.) top-most in the middle,and Aristarchus (40 km.) on the right on the picture.

Crater name is taken from the german mathematician, astronomer and astrologer Johannes Kepler (27.12.1571-15.11.1630). He is best known for his laws of motion of planets. Astronomers, later, codified this laws by his works : Astronomia nova and Harmonices Mundi.
