Has anyone out there seen or used one of these? Any photos? Dare I
ask, does anyone still have one? Here's the recent references I can find: From Peter Abrahams, Portland, Oregon, telscope-at-europa-dot-com Harold Haggart. Oregon City. ATM in 1920s, died 1984. Haggart-Aquila 6 inch Maksutovs produced circa 1960, one 20 inch Newtonian / Cassegrain / Springfield / Coude. Sky & Telescope, September, 1952, pp282-285. Roland Christen: I have seen worse, though. Back in 1968 - 1970 there was a scope being offered called the Haggard Aquila. It was supposedly a 6" f15 Maksutov, and I lusted after that scope. It was affordable, unlike the 4" Unitrons, and I had little or no money for a scope. Years later someone told me the sad story of his ownership of this instrument. First, he discovered that it was really a Dall Kirkham design with a plain plate glass window for a "corrector". Next, he discovered that the primary mirror was stopped down with a 1" ring of black tape around the periphery, so it really only had a 4" clear aperture. When he removed the tape, he found a humongous turned edge which made the scope totally useless. With the tape back on, stars were little astigmatic triangles at focus. Rotating the "corrector" showed that the plate glass material was severely astigmatic. It was never optically polished, just cut round out of a piece of cheap window glass material. If you go back to S&T ads of that era, in their ads you can read the hype about this scope and how optically superb it was. People are forever hopeful. |
