... Main mirror assembly consists of: . mirror cell structure . ... relief mechanisms . ... central bed Main mirror is fixed in the mirror cell in axial direction by three rigid supports. ... The butt relief of main mirror is implemented according to Lassel and involves 18 relief mechanisms, three of which are replaced by rigid fixing supports after the adjustment. The side relief is similar with the relief mechanisms working in both directions since mounting points are glued to the mirror. ...

These are the fellows that showed up at the Observatory on February 20th to help with the gargantuan and nail-biting task of getting mirror out of the telescope safely, out of the cell safely, into the box safely, and put into the truck safely. ...

. Will Saunders of the Anglo-Australian Observatory imagines a relatively simple 16m telescope at Dome C. A nearly flat, steerable reflector (right) receives light from the sky and directs it onto the primary mirror (left). The primary mirror focuses light onto a prime-focus unit halfway between the two mirrors. This unit could be a camera, a device that holds optical fibers for capturing the light, or a secondary mirror reflecting light through the primary's central hole. Andrew McGrath, AAO
