This area is one on which if you observe it, it will not make a good impression, given that it is so troubled by serious impacts. Wilhelm (107 km), is one of the craters resulting from these impacts. Its floor is low and smooth to the west, and high with hills to the east.
Although the edge is easily distinguished through a telescope, it is highly affected by other smaller impacts and besides this is irregular from the beginning when the crater was created.
This crater is filled both inside and outside by its satellite craters.
Over Wilhelm and all its neighboring craters are scattered materials ejected from Tycho crater (85 km), which have a white colour, making it to shine in the intense sunlight.
Because in these pictures the sun does not fully illuminate this area, we can observe more "disorder" on this crater and in his appearance, fueled by the shadows of its edge.
Because it is situated in an area so affected by so many impacts, Wilhelm can not be seen through binoculars, because is easily overlooked among so many diverse features. The best can be seen through an astronomical telescope wich approach the Moon more.
