Explore Scientific 127mm Air-Spaced ED APO f/7.5 Triplet Refracting OTA Telescope

The Explore Scientific 127mm f/7.5 ED APO Refractor Telescope is one of the most innovative ideas in high-quality apochromatic designs. Beginning with a tube fashioned from aluminum and stainless steel, what sets them apart starts from the inside. Explore Scientific uses advanced technology like its ED (Extra-low Dispersion) FCD1 (Dense Fluor Crown) glass, developed by Hoya Optical of Japan, to enable the production of lenses that offer superior sharpness and color correction by minimizing color distortion. This glass type offers a more durable and long-lasting solution to produce an optic to minimize chromatic aberration over delicate fluorite crystal objectives that are prone to fracturing and absorbing moisture. These true air-spaced apochromatic triplets have refinements like EMD (Enhanced Multilayer Deposition) coatings, which absolutely eliminates light scatter and maintains image contrast. Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray li
