Oops, make that:

   3      -1065         385  MIRROR       76.2

if desired, making it about f/7.  With its already smaller
required size and the vignetting from the other mirrors,
this mirror can be reduced to that size with only a bit of
additional loss in illumination (< about 1%).  Sorry I
didn't notice earlier.
