Optical Alignment
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.
Viewing Comfort and the Preservation of Precious Light
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.
Many premium small refractors don't include some basic accessories like a viewfinder. This is often done to keep prices down. Those manufacturers rationalize that its owner simply will not need a viewfinder... wrong!
The Explore Scientific 8x50 produces a wide 6° field of view and allows precision focus of both main objective and eyepiece illuminated reticle. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders. Our illuminated reticle is truly designed for finding objects with its open center (so you don't mask the object you are centering with cross hairs) and scale markings for 1.5°, 3°, and 4.5° (the edge of the field of view is the 6° boundary).
The 55° apparent field, long eye-relief eyepiece produces a bright 15.5mm exit pupil and will allow you to find faint galaxies, comets, and nebulae. All optics are fully-multicoated to insure maximum contrast.
Universal Mounting Plate
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.
You can mount the ED 127 to many popular equatorial and Altaz mounts, including Explore Scientific mounts.
