The remarkable limbo East!

You can see Mars, Jupiter or Saturn, that these are the most spectacular planets that may appear in the eyepiece of a telescope, and never see any change as can be seen in one night of observation of the Moon. Impact of comet Shoemaker-Levy 9 in 1994 generated impressive and rapid changes in Jupiter's atmosphere, and the great storm of Saturn proved spectacularly for us here on Earth, since late 2010 but these events are observed once in a lifetime, so if the observer has luck and may occur in a small strip of the planet. Already the moon changes occur across its surface and continuously, these changes are due to the angle of illumination that switches on the moon approximately half a degree per hour.
In the attached photo the eastern limb of the Moon is well known. The craters exist there are nearly visible, or can even be visible to the naked eye, depending on the quality of vision of the observer. Yet the picture is dominated by the crater Petavius ​​in the corner below right. To recognize it more easily simply observe the crater that has a groove connecting the central peak to its edge. The Petavius ​​is perhaps the most fascinating crater located along the eastern limb of the Moon. She is young enough to have their massive central peaks and terraces blocados reasonably preserved, but what separates it from similar Langrenus and complex craters is your characteristic interior. The trench that arises from the central peaks and moves toward the west wall does not compare to any other channel crater on the Moon. A wonderful connection that has only clue that image but that is revealed in images taken by the Lunar Orbiter probes IV and the Chinese Chang'e-1, is that the massive main channel bends slightly at the peak and continues northward (left), making it incredibly narrow. Another channel radiating southward from the peaks. As the main channel and the channel to the north, it is also wider near the peaks and thins as you get away from them. This suggests that all three are connected with the uplift peak and the center of the inner crater. Previous observations indicate that the center of Petavius​​, was uplifted, but to have a confirmation of data needed for high-resolution topography.
Two types of materials flow in Petavius ​​and close it. The old dome located slightly below the south wall was probably built from lava that erupted and the soft shells of material beyond the southern ring materials are melted by the impact. With all these fascinating features with which the other Petavius ​​could share the spotlight in this region of the Moon?
Filled the walls of the crater Langrenus terraces are well observed here with dozens of secondary craters on the plain around. Trio of craters in the northern Langrenus, Bilhars, Atwood and Naonobu there is a beautiful cluster of these secondary craters. These secondary craters would be the Langrenus or some other? Among Langrenus craters Petavius ​​and the area is dominated by Vendelinus and houses younger and smaller craters. One of these craters in particular stands out, is the crater Petavius ​​B with its system of rays well known.
I'll ending here, because the amount of notable formations visible in this photo alone would merit a treaty and not just these few lines!
