~Corrected Gregorian~
work in progress

A Gregorian with a sub-aperture corrector for diffraction limited imaging across a .5 degree field of view and 25mm fully illuminated field. Original optical design. This has become a long term back burner project. The OTA mechanical assembly is built but I still need to have the optics made.
