Description

The Explore Scientific 80mm f/6 Air-Spaced Triplet ED APO made Wired Magazine's Wish List for cool gifts and is a perfect instrument for demanding wide field observing and astrophotography.

 

Rugged and portable, unlike other "grab-and-go" small doublet ED refractors, this a true three-element apochromatic telescope capable of producing research-level image quality. Dr. Mike Reynolds used this telescope to make the first ever images of shadow bands on clouds during the total eclipse of the sun over Easter Island on July 11, 2010.

 

In addition to fine optical quality, the deluxe focuser, diagonal, and case, make this telescope an extreme value!

 

Hoya ED Glass, a Critical Element of Explore Scientific ED Apochromatic Refracting Telescopes

 

Explore Scientific uses 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 the color dispersion (chromatic aberration, or the "false" color fringing seen around bright objects that happens when light rays pass through standard crown-and-flint doublet objectives). 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.


 

High Performance Optics Demand a High Precision Focuser

 

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


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.

 

Universal Mounting Plate


You can mount the ED 80 to many popular equatorial and Altaz mounts, including Explore Scientific's 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.

    Comments about Explore Scientific 80mm f/6 Air-Spaced Triplet ED Apochromatic Refractor Telescope:

    I got this scope with imaging in mind, but I have not had the opportunity to go imaging as of yet. I did take it out for a viewing session and the quality was very noticeable. I will try and give a more descriptive post once I get a few imaging session in.
