  • QUESTAR IN KENYA On Safari With The 700 “QUESTAR IN KENYA On Safari With The 700”, the complete six (6) page full color illustrated brochure featuring a series of color photographs of wildlife taken by Eugene J. Cohen, M.D.. during one of his annual visits to Kenya.

    The photographs in this brochure were taken with his Questar 700, the first production version of the patented 700mm f/8 catadioptric telephoto lens that were introduced in 1976. This demonstrates the kinds of results that one could expect to attain when safely photographing wildlife from some distance with the compact and relatively lightweight (about 4 lb.) Questar 700 lens using a camera with the then recently released (1977) Kodak EKTACHROME 200 Daylight consumer slide film. Wildlife shown in the brochure include: Lions, Cheetah, Eland, Gazelles, Giraffes, Zebra, Hippopotamus, Wildebeest, Impala, Dik-Dik (captured in mid leap), a Rock Hyrax, and others. Also shown are several birds including a Gray Crown Crane, Augur Buzzard, Crowned lapwing (Crowned plover), and more. Some of the animals were photographed in repose, while some were captured while in motion showing how sharp the image could be even when photographing at f/8.

    Keep in mind that in the late 1970’s and through to the digital age, these were very good photos. As famous and well-regarded as the EKTACHROME film was, many of the most memorable NASA images were taken with this film, we at Company Seven wonder at what results could be obtained today using the Questar 700 lens with a state of the art digital SLR camera with images processed with modern software.

  • Photographing In The Rockies With the Questar 700, cover QUESTAR “Photographing In The Rockies With the Questar 700”, the complete four (4) page full color illustrated brochure featuring a series of color photographs of wildlife and scenery taken in the Grand Tetons and Yellowstone regions in the USA, over July.

    The photographs in this brochure were taken with his Questar 700, the first production version of the patented 700mm f/8 catadioptric telephoto lens that were introduced in 1976. This demonstrates the kinds of results that one could expect to attain when safely photographing wildlife from some distance with the compact and relatively lightweight Questar 700 lens. However, the close up capabilities of the lens too are demonstrated as some objects were only 10 feet away. For comparisons, some animals (Elk, Moose, Mountain Sheep, Pronghorn antelopes, and a Yellow-headed Blackbird) and features including “Old Faithful” were photographed with a normal 50mm lens, then were again photographed but with the Questar 700 for comparison with stunning results! All photos were taken with KODACHROME 64 film, with a film speed of 1/125th second.

    Consider how in the late 1970’s, and through to the modern digital age, these were very good photos. As famous and popular as the KODACHROME 64 film was, we wonder at what results could be obtained today using the Questar 700 lens with a state of the art digital SLR camera with images processed with modern software.

  • Patents related to the development and evolution of the original Questar 3-½ telescope and to other Questar products described at this site that refer to their patents:

    Questar logo from 1990's (27,482 bytes)
              U.S. Patent Number and Date                                                           Brief Description
    1480793   Jan 15, 1923 Star map with stars represented by luminous material,
    with symbols varying in size representing magnitude.
    2628529   Feb 17, 1953 Reflecting telescope with auxiliary optical system. A modified
    arrangement of the Questar optical system not put into production.
    2649791   Aug 25, 1953 The basic arrangement of what would become the Questar showing the Moon
    Map and the Star Chart, the conceptual equatorial Fork Mount with Control Box,
    and the rotating optical tube assembly.
    2670656   Mar 2, 1954 The basic arrangement of the Questar optical arrangement
    components support and focus control mechanics.
    2693032   Nov 2, 1954 Proposed arrangement for a portable fork mounted telescope based
    on the Questar but where the telescope base serves as a housing for safe
    storage and transport of the telescope optical tube and other components.
    D175388   Aug 23, 1955 Telescope, showing the ornamental design of the telescope from most perspectives.
    This was filed in Sept 1954 and so this shows a very early production arrangement
    that employed a post style pick-off mirror support.
    2753760   Jul 10, 1956 "Multiple Image Telescope" shows concepts to convey
    light from either the telescope’s main optics or the Finder to the Eyepiece Port.
    This too predates the final production arrangement, for example a pick-off mirror
    is used for the Finder instead of the prism shown in this application.
    4061420   Dec 6, 1977 "Catadioptric Lens System" the new design implemented in the Questar 700 lens.
    The invention provides a highly corrected catadioptric telephoto lens made.
    up of an aspherized negative meniscus corrector lens, a Mangin trype primary
    mirror, a secondary mirror, and two additional corrector lenses in line.
