Description

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, a 2" 99% reflective dielectric diagonal, and a deluxe case. You can be confident that the quality and construction of these telescopes will allow heavy use for many years and are backed with a transferrable Five Year USA Limited Warranty.

 

EMD™ (Enhanced Multilayer Deposition) Coatings eliminates light scatter and maintains image contrast.
Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light.


 

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

 

Optical Alignment

 

We precision collimate every Explore Scientific telescope at our factory to give optimum performance. Although you may never need to adjust optical alignment, our 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.

 

Viewing Comfort and the Preservation of Precious Light


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.

 

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.
