Re: [ATM] Flat Field Cass with Hougthon subaperture corrector. WAS:corrected dall-kirkham telescope
The company is working on a design for 12.5" scope...
Would it be possible for an ATM to build the optics for this sort of scope? Would it be possible to purchase the correcting lenses off the shelf?

Checking the link to the (corporate ?) website, the theoretical
spot diagrams are truly impressive, as are the 20" aperture and
32000 USD pricetag. Has anyone on the list here built such large
aperture catadioptric system, and actually get a result that
approaches this (I have not)?
