This image of the moon shows the moon one day before last quarter when the moon was about 65% illuminated. The large crater with the rays extending from the crater just to the left of center is Copernicus. The crater below it and to the left, that also has rays extending from it, is Keplar. Also visible is a prominent ray extending (horizonally in this image) from the crater Tyco on the right of this image near the terminator (the ray extends across Mare Nubium). Rays are formed by ejecta thrown from the crater during an impact. The craters with extensive sets of rays are generally younger than other nearby areas of the moon's surface. During a favorable lunar libration, it is possible to view Mare Orientale near the limb of the moon at the very bottom in this image.
This CCD image of the moon was taken with a Takahashi Epsilon 180ED telescope using an STL-11000M CCD. The image was taken from my backyard in Scottsdale, Arizona.
