I am selling my 1999 Questar Duplex 3.5 with Zeodur mirror, Broad-band/Low-reflections coatings, and Powerguide II. It comes with all standard items, including 16mm and 24mm Questar eyepieces, 1.5" aperture solar filter, legs, instruction manual, standard case and keys, and shipping drum. Everything, including optics, is in superb condition. What makes this Q particularly sweet is that I just had it fully serviced in the fall by Questar (cost/value: $410). You will get certification to that effect as part of the sale. I am selling only to finance the purchase of a Q7. The price is $3650 plus shipping, only within the continental U.S.
If interested, call me (512-231-9964) or email for the serial number.
