    Used Explore Scientific ED127 Triplet APO Refractor - Carbon Fiber - SOLD

    The Explore Scientific 127mm f/7.5 Air-Spaced Triplet ED APO produces a visual experience that is often compared to much larger aperture reflector telescopes. The contrast and resolving power can reveal stunning detail on planets and deep sky objects alike.

    The designers of the Air Spaced Triplet ED Apo Series pursued to produce top-quality refractors with lasting value. The optical solution was to provide a traditional air-spaced design mounted in a rugged, adjustable lens cell. This design, shaped from experienced craftsmanship and polished from genuine HOYA FCD1 (Dense Fluor Crown) ED (Extra-low Dispersion) glass, a critical element to produce images that refractor afficianados know can only be obtained with a high-quality true apochromat.

    The owner of an Explore Scientific ED Apo will appreciate the attention to detail and the standard hardware which includes a precision two-speed focuser and a 2" 99% reflective dielectric diagonal.

    All Explore Scientific ED Apochromatic Refractor telescopes include a precision Ten-to-One, Dual-Speed Focuser as standard equipment. The eyepiece holder uses a compression ring to prevent the eyepiece or camera barrel from scoring.

    Exploring the fine features around the Moon's Hadley Rille will put to test observing skills of any astronomer as well as precision of telescope optics. Better optical quality dictates more precise focusing.

    This is especially true when observing at high magnification or when making CCD images. With a standard focuser, you will find that a tiny nudge will throw out focus and turn your night into one of frustration.

    So Explore Scientific included as standard equipment, on all ED Apos, a ten-to-one, two-speed Crayford-style precision focuser with tension adjustment and lock to obtain and hold perfect focus. They think you'll agree that such precision is worth it.

    Explore Scientific precision collimates every Explore telescope at their factory to give optimum performance. Although you may never need to adjust optical alignment, the ED Apos allow for optical centering to collimate the lens elements should the telescope ever require it. One of the bonuses of ownership of a refractor is that, compared to standard reflector telescopes, they almost never require re-aligning of the optics (collimation). However, any telescope that is subjected to shock may require optical alignment.

    Removing the dew shield, you can access the alignment screws, which you can adjust yourself by referring to the instructions. You can also send it to Explore Scientific's Service Center for alignment. A standard service charge applies.

    The Two Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror. The purpose of a diagonal is to securely hold your eyepiece and to give you a comfortable viewing angle.

    Provided as standard equipment, Explore Scientific's Two Inch Dielectric Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment. Ultra-high reflective coatings (99% reflective) composed of multiple thin layers of dielectric material delivers maximum light output.

    Both 2" and 1.25" eyepiece holders use compression rings instead of a simple set-screw to more securely hold your valued eyepiece (or imaging device) and to minimize scoring of eyepiece barrels. You can thread standard 48mm filters into the barrel.

    Although it cost more, Explore Scientific chose carbon fiber for the telescope tube and dew shield for its high strength-to-weight ratio and its low expansion characteristics when subjected to temperature variations. This helps to keep the instrument light in weight and keeps the instrument focused even if the temperature drops.

    Even though this telescope uses a carbon fiber tube making it much lighter, they supply a handle to easily grip the telescope for mounting and placing it back in its case. In addition Explore Scientific slots the handle to accept a standard 1/4x20 bolt to attach a camera.

    The Universal Adjustable Mounting Plate of the ED 127 fits on mounts supplied by Explore Scientific, Vixen, and Celestron AVX and CGEM. It also attaches to photo tripods with standard USA or European thread attaching knobs. You can mount the ED 127 to many popular equatorial and Altaz mounts, including Explore Scientific mounts.
