What a holiday present this would be! Twenty inch mirror by John Hall of Pegasus with papers (which state a wavefront error, peak to valley, of 1/21.83), primary has 96% reflectivity coating that is six years old and in very good condition, 2.6" secondary has 98% Endurobrite coating, constructed by Pete Kron, all in very good condition. Includes Telrad (but not the ST80 and the DSC/encoders in the picture).
An excellent performer for $4,650 shipped CONUS. Call me a 610 453 4148 if you want more information.
