Or to the left? It's a boom extended from the service module near the camera with a sensor (gamma ray spectrometer for surface composition) on the end. The boom is the straight bit in the middle, the curvy bit is the sensor's cable.

thanks. does it touch the crater or this is a visual deception?

The metal pole is attached to the orbiter, and does not touch the crater at all.

Because the sensor boom is mounted near the camera, it extends into the camera field of view. The boom is 7.6 metres long, the Apollo CSM is in orbit 100 km above the surface.

The spectrometer detects gamma radiation from the lunar surface. The frequencies detected give data on the chemical elements present on the surface.
