14" f/4 f/16 Classical Cassegrain optics by Gene Fair, full thickness pyrex mirrors, diffraction limited, no zones or turned edges, never used, made in early 1980's when Gene was living in Pomona CA.

Gene's test results show the primary as 0.029 lambda (1/35th wave) with an error of +/- 0.017 lambda (1/60th wave) at 5000 A. The secondary is rated as lambda/20.

These mirrors need recoating, the original aluminizing is deteriorated.Replacement cost is $5000-7500 for this quality to be made today. Priced to sell at a modest $3500 for the set, plus shipping costs.

Email or call if you have any questions, would be happy to fax Gene's test certification.
