[ATM] ATM re: large Schmidt camera?

The "obvious" solution to me is a Lenseless Schmidt.  (Rutten and Venrooij,
chapter 8) Aperture stop at ROC, camera at focus.  The focal plane is still
curved, but that's where a field flattener could work.  As for the details,
aperture sizes vs mirror diameter, flattener specs, all that, you're on your
own.
