• 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 light.

  Upgrade your telescope’s ability by mounting the ED 127 to many popular equatorial and Altaz mounts, including Explore Scientific's new TwiLight I and TwiLight II Altazimuth Mounts. Photographers, who are looking for super high resolution optics, can mount the optical tube assembly to their existing medium-duty camera tripod. A release knob allows the tube assembly to rotate so that the camera can be positioned at any angle. The Universal Adjustable Mounting Plate of the ED 127 fits on mounts supplied by Explore Scientific, Vixen, and Meade LXD55/75. It also attaches to photo tripods with standard USA or European thread attaching knobs.
