Copernicus is nicely illuminated to show detail in the terraced walls & the cluster of central peaks reaching up to 1.2 km. The relatively flat floor is covered in many small hills. Apart from the one craterlet embedded on the Eastern wall (Right), the small number on the floor are not visible in this image. North is up.

Your capture includes the odd-like feature at east of the crater - producing a nice shadow effect.

 

There is a wall-like collapse due north and south of it, so why did this portion form. Was it due to a more hardened make-up material there, or simply due to the amount of material at said location when the initial impact occurred?

 

It doesn't appear like a small impact crater produced it, as the material looks similar to the rest of the outer terrain around the crater's eastern rim.
