R1: Longomontanus had several terraces in its walls with secondary impacts. Its peaks were slightly off-centre.
R2: There were secondary craters in its NW wall and floor, giving it a rough, craggy appearance.

Observation 2: I viewed this crater under better transparency and seeing. The craters in the NW wall were more easily seen. I could make out several on the floor and up the crater wall. |
