A look through the camera viewport: In front the stainless steel mirror, then mirror MMC2b, behind it the reaction mass with coils; in the back the modecleaner tubes.
A view from SSE: At the top the intermediate masses with coil holder; at the bottom mirror MMC1b and it's reaction mass between range limiters.
A view from SSW. The thin (50 µm) copper wires are the electricity supply for the coils of the reaction mass.
