    Re: Lunar distance by photography
    From: Peter Monta
    Date: 2024 Jul 13, 19:02 +0000


    Longitude determination by photography of the Moon and stars is
    explained in considerable detail in the wide ranging book "Topographic
    surveying, including georaphic, exploratory, and military mapping, with
    hints on camping, emergency surgery, and photography," by Herbert M.
    Wilson, 1908.

    That's a nice account of photographic lunars.  Only 50 years between that and Markowitz's dual-rate moon camera.

    The internet telescope service, iTelescope, has a new feature in which the Moon can be photographed directly (instead of being the center of a no-go zone).  Could be useful for evaluating the accuracy of image processing; I may give it a try.  Of course a 60 cm scope on an accurate mount is the furthest thing possible from a handheld photo on an unsteady nautical platform.

    Cheers,
    Peter
