    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.
