1963 Questar Duplex 3.5 


Questar 3.5"  This scope has been reworked by Questar sometime since the original production date of the OTA in 1963. (This is the R9 designation in the serial number) It has the low expansion cervit mirror (CV) and broad band coatings(BB - Questar's equal to EMC coatings in their day) Optics and coatings are in excellent condition and the scope has the signature deep purple silk screened star chart on the barrel which slides up for a dew/light shield. Typical and expected Questar pin-point images. Perfect airy disc. All controls are smooth and precise. The duplex version allows the OTA to be quickly, easily (and safely) removed from the mount to use atop a photo tripod or other scope. This system comes with: Questar Duplex scope and fork mount. Leather carry case which houses; Brandon 24 and 16mm Erfle screw in EPs * Off-Axis Glass-Solar filter * Kendrick Foile Solar-Filter in cell, full aperture * 1.25" standart eyepiece holder * extension cord for RA drive * equatorial legs for table top use.
