Technical description:
A closer look at the top of the telescope shows the MegaPrime upper end installed on the top ring of the telescope structure.  All the MegaPrime instrumentation is supported by a very stiff base held high above the telescope by four arms (black) attached to a base ring (white). The Wide Field Corrector is bolted to the base from underneath; its first lens is visible on the picture.  The rest of MegaPrime is protected by a cover, seen in the picture as a black and silver structure.
