    This performance of this 4" focuser Takahashi 5.1" ED triplet refractor is too good to let it be called simply an apochromatic scope. Only the term ortho-apochromatic is accurate enough to describe its optical excellence, both visually and for medium format and 35mm/large format CCD imaging . . .

    This big Takahashi 5.9" ED triplet refractor is optically too good to be called simply an apochromatic scope. Only the term ortho-apochromatic is good enough to describe its optical excellence . . .

    This TeleVue TV-60 is a high performance 2.4" apochromatic doublet scope that will surprise you as much with the magnitude of its performance as it does with the mini size of its compact "go anywhere, any time" body . . .

    The Astro-Tech AT115EDT 4.53" f/7 ED triplet apochromatic  refractor offers more performance and features than similarly-priced smaller aperture competitive refractors, and a markedly lower price than competitive scopes with the same aperture. All in all, an exceptional value.

    Some observers feel that the Astro-Tech AT130EDT 5.12" f/7 ED triplet apochromatic refractor compares favorably in performance to scopes nearly four times its price. We won't go quite that far, but we will say that the AT130EDT is an exceptional performer and an exceptional value.

    The Takahashi FC-100D is Takahashi's latest update to the 100mm fluorite refracotor.  The FC-100D uses the Steinheil design with the fluorite element in the rear and an eco-glass front element.  This apochromatic telescope provides outstanding views, both visually and with digital imaging hardware.
