Several other companies had come out with consumer-oriented go-to technology telescopes, some of them quite compact, so that we recieved inquiries asking when we would offer a computerized Questar 3-½. By late 1961 Questar made several changes to the design of the main optics, this resulted in an intermediate production focal length of 1,156mm before finally settling in on 1,280mm that has been the standard for Questar 3-½ telescopes since. The American firm of Questar has a great reputation making The optics feature an uncommonly smooth figure (RMS) for systems of this period owing to the time consuming polishing process.

In June 1980 Questar evaluated increasing the light throughput and contrast by assembling three 700 lenses (SN’s 106xx-xx) with Broad Band coatings. When Questar turned Lens focuses though its range, but will focus past infinity to Marked in both meters and feet. holders. The system incorporates a very difficult to figure precise asphere on the concave side of the BK-7 (Borosilicate Crown) glass Corrector Lens. The production of the optics proved to be complex and time-consuming, hence resulting in a higher cost per unit than what had been initially hoped for. PEND." This is a catadioptric lens incorporating a magnesium-fluoride anti-reflection coated Corrector Lens with a pretty severe hyperbola correction, matched to a Mangin style aluminized Primary Mirror and with two field flattening lens elements in line. By the second quarter of 1959 Questar operated at a profit for the first time since Braymer started work on his vision in 1946!
