RE: [ATM] Use of bearings in (static) mirror cells

That is a cool idea...

I have set of makstutov optics and that would work as a cool focusing
mechanism...

The idea of a conical mirror that is supported by a compliantly mounted
arbor is neither new nor desperate. I have mounted several conical
mirrors
as large as 14", using the centrally supported conical mirror with the
central arbor mounted to my compliant focuser.  This arrangement not
only
allows for the primary mirror to be moved for focusing, but also allows
for
collimation by adjusting tip-tilt of the focuser-primary mirror unit.
There
is no floatation cell.
