Sold in minutes, thanks Herb!
This Schupmann Medial "kit" consists of a single-lens objective and cell, Mangin mirror and tilting cell, and relay lens with tilting cell. The objective and Mangin mirror are two halves of the same BK-7 blank so color correction should be superb. The refractive surfaces are uncoated, however the silvered Mangin mirror is showing a bit of spider-webbing from age. These unused components were made by the famed Max Bray for me as a hobby project many years ago. Sorry, no Zygo data at this price, but the system was tested against a flat to his personal standards. I can not offer tube construction or collimation advice since this is a somewhat advanced project for the ATM. You will receive the pictured items, the original design data, and Jim Daley's paper on Schupmann medial telescopes.

Asking $350 obo. Sorry, no PP. Money order or Cashier's check preferred.

Clear skies,
Dennis
