You are bidding on: Questar Seven TelescopeS/N P-7-677-BB-DPMost Questar Seven's have been made for governments and industry for applications including surveillance, research, and astronomy. The very first Questar Seven optics set was completed for Questar on 26 January 1967, Serial No. P-7-1. By June 1998 there had only been a total of 826 Questar Seven optics sets made - with the most recent being Serial No. Z-7-826. It would be difficult to find any other production telescope that has the combination of compact mechanical precision and efficiency, with optical performance and durability which these instruments afford at similar cost.The optical design is based on a Caprellian designed 7 inch (178mm) aperture Maksutov Cassegrain telescope with a nominal 2,413mm focal length. OUR Questar Seven comes in a sturdy carry case w/ two keys. There may be certain additional parts/lenses/accessories needed for the smooth operation of this Telescope. It has no fork mount base and/or tripod. There also seems to be a cap or viewing lens missing from front center. (see photo #2). There was a nickel size 2-sided mirror (not pictured) that was found inside case. Please see photos for further details I am not familiar with the operation of this scope and don't know how to check it out. Please ask any questions that would help you better assess its condition.
