Büsching is a lunar impact crater that is located in the crater-covered southern highlands of the Moon.

[1] The similar-sized crater Buch is located adjacent to its southwestern rim, and further to the southwest lies Maurolycus.

This crater has been eroded by a long history of subsequent impacts, so that the rim has been worn down and the edge rounded.

The interior floor is somewhat irregular and lacks a central peak at the midpoint.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Büsching.
