Explore Scientific ES - 127mm f/7.5 ED Apo OTA w/ Dlx Case & Accessories
Air-spaced triplet ED APO refractor that utilizes Hoya ED glass.
|
|
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, an 8x50
erect-image, illuminated-reticle viewfinder, 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. |

High Performance Optics Demand a High Precision Focuser
|
| 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 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.
|
 |
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.
|
 |
The Explore Scientific 8x50 Erect-Image Viewfinder with Illuminated Reticle is standard equipment. |
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!
While it's true that ED Apos in this aperture usually
have short focal lengths, it still is a challenge to successfully aim
the telescope without a viewfinder. So we decided to offer a superior
class 8x50 viewfinder as standard equipment.
| The illuminated reticle of the 8x50
Viewfinder with its scale markings and open center not only helps you
center objects precisely, but gives a reference of the exact field of
view in degrees. The deep red illumination is continuously variable to
provide the desired brightness. |
 |
|
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.
