~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.
