Thermal oxide patterning method for compensating coating ...

mirrors already come close to meeting requirements for Lynx and rapid progress continues to be made. Unfortunately, preferred mirror reflective coatings, such as iridium, typically exhibit a compressive stresson the order of 1 GPa, which can distort the ~0.5 mm thick mirror's precisely-figured initial shape by many times the tolerance limit4.

Telescope stepper motors ... or? — Parallax Forums

MMT = ple mirror telescope. I got a lot of ideas when building a 144-servo driven motor mount for the 40-inch primary objective mirror. It could shape and figure the mirror in real time. But the concept for the telescope's alt-az mount is the same as your scope. Remember you can program and design different drive rates.
