I figured that someone on this site must know someplace or someone who would be willing to make a 12.5" f/20 mirror.  I'm planning on using this for solar work, thus the long focus.  The mirror should be spherical (which should be easier to figure) since over around f/12 this doesn't matter according to Rutten and van Venrooij, as the blur spot will by smaller than the Airy Disk (f/8 and slower for photographic work).  Any help would be greatly appreciated.
