The two optical elements Mirror and corrector are 1/10 wave as is all of Roland's telescopes! Imagine that – 10 inches of 1/10th wave optics!! Who else is doing that? After the optics were bought from ARIES Optical, Roland was dissatisfied with their quality and totally refigured them to his high specs. Roland didn't make much money on these scopes after all of his extra work on them. Perhaps, this is why he dropped continuing the Mak-Cass production.
The two optical elements have to be more than 1/10 wave corrected. 1/10 wave is what A-P guarantees is the wavefront quality at the eyepiece and being mirrors, both secondary and primary surfaces have to be figured to 1/20 wave. Roland's said he stopped making this design because it was a "female dog"

to make with its aspheric curves.
While Roland put considerable thought into the cooling aspects of the scope, such as a rear-polished quartz primary, fans, removable backplate, etc., the fact remains that large scopes will have trouble catching up to ambient when it drops faster than the rate at which they can reasonably cool off. In the northern climes, especially when it's a bit dry, temperatures often keep dropping into the early morning. Any large scope, including the venerable A-P Mak, will have to wait till this time for optimum performance. FWIW, my 7" refractor performs optimally only at this time, not from its own cooldown problems but from the fact that the atmosphere had stabilized by then.
