The pictures shows craters in the eastern part of the lunar disk . Here are craters of all sizes , most of which Stevinus Snellius and Reichenbach 's satellite craters.
Reichenbach (71 km) is a crater with a very affected edge , double to the north. Although this seems oval , this and all the craters are mostly circular but seen like that because of their position on the Moon .
We take as reference the first image above, which shows the Moon in the correct position as seen from the Earth ( the second image is reversed as seen through the astronomical telescope ) .
North of Reichenbach observe 2 straddle smaller craters . They are Reichenbach A (34 km) and B (44 km). The latter has the whole edge and a central peak .
East of all these craters mentioned above , see some big black " holes ", because they are covered by shade, being at the terminal of the Moon (at the boundary between light / dark ) . These are Stevinus (75 km) (bottom right), and Snellius (83 km) , north of Stevinus . There are not many things to see on these craters in this light , being flooded by darkness, but we may notice the edges , which on Stevinus is sharp and and very affected on Snellius looking very messy .
