Looking for a pocket-sized telescope? The 80mm f/6 Air-Spaced Triplet ED Apochromatic Refractor may be the answer. Ok, it’s not quite that small, but at 7.5 pounds, this tiny telescope is portability perfection and the winner of our TopTenREVIEWS Silver Award. Size is just one small way this instrument stands out among astrophotography beginner telescopes. This scope is so versatile. It’s great for viewing comets, deep sky objects, double stars and even terrestrial targets. Above all, this apochromatic refractor offers excellent quality optics at a reasonable price. It’s an ideal second telescope or first telescope for astrophotography.

Blurb:
Offering true diffraction-limited optics and designed with portability in mind, Explore Scientific’s ED80CF telescope is a perfect grab-and-go instrument for exploring the skies. This refracting telescope features an 80mm air-spaced, triplet objective lens with genuine HOYA ED glass that is truly apochromatic with our proprietary EMD coatings to produce images of such high contrast and sharpness that we welcome direct comparison to any other ED APO in its class. Witness the magnificent desolation of the endless variations of the lunar terrain, the subtle olivine modulations and storms of Saturn and the serene structure of its ring system. Explore the broad range of celestial objects, including the deep sky treasures of the entire Messier and Herschel catalogues. A lightweight carbon fiber tube eliminates focus change due to shrinking or expansion due to temperature changes and a retractable dew shield protects against moisture and stray light. The telescope also has a three-point push/pull collimation cell, a two-speed two-inch focuser and a precision-polished two-inch mirror diagonal that is 99% reflective.

Extended copy:
A great entrée into the realm of serious telescopes, Explore Scientific’s ED80CF combines high-end optics and well-executed design to create an exceptional instrument for everything from deep sky observation to comet-chasing to astrophotography.
With its 80mm triplet objective lens, the refracting telescope uses true diffraction-limited, apochromatic optics to open up the skies revealing wonders like the magnificent desolation of the lunar terrain or the vibrant nature of Saturn with its swirling storms and serene ring system structure. The lens is air-spaced with a middle element made of genuine HOYA FCD1 extra-low dispersion glass, and all air-to-glass surfaces have been multi-coated with Explore Scientific’s proprietary EMD (Enhanced Multi-layered Deposition) coating. All of these features collide to produce stunning high contrast images with crisp definition that encourage viewers to explore the celestial secrets of a broad range of subjects, including the deep sky treasures of the entire Messier and Herschel catalogues. The quality of the optics also allows those seeking to push magnification based on their choices of eyepieces or focal extenders to do so without sacrificing clarity.
The emphasis on precision continues outside of the lens construction with the addition of a three-point collimation cell that allows for pinpoint adjustments of the objective lens. The two-inch focuser has two-speed control, and multiple set screws are in place to lock all elements.
Sized to fit a vast range of eyepieces, the included diagonal has a precision-polished, two-inch mirror that is 99% reflective to transmit even more light. The tube that connects the diagonal to the scope itself is also tapered for added security should one of the set screws be accidentally loosened.
Beyond the optics, the ED80CF can list its carbon fiber housing among its many assets. In addition to being lightweight, the material prevents unintended focus changes from the tube shrinking or expanding due to temperature fluctuations, which can be crucial to maintaining a continuous clear image during a long night of astrophotography or observation. The scope also has a retractable dew shield that prevents moisture from building up on the lens and eliminates the image interference caused by stray light. A bracket for a finder scope is also mounted on the tube.
For added versatility, the telescope comes with two extension tubes, has a vixen-style mounting plate and is equipped to fit both European- and American-style tripod threads.
To further guarantee its standing in the grab-and-go class of observation tools, the telescope comes in a deluxe storage case with a clamping lock system and a molded foam interior that protects the device and its accessories.
All in all, the ED80CF maximizes its exceptional optic elements and high design standards to create such brilliant images that Explore Scientific welcomes direct comparison to any other ED APO telescope in its class.
 

The Critical Element: Optics

Explore Scientific uses ED (Extra-low Dispersion) FCD1 (Dense Fluor Crown) glass developed and manufactured by Hoya Optical of Japan. Using the right glass with the appropriate properties enables the production of lenses that offer superior sharpness and color correction.

The optics used in Explore Scientific ED Air-Spaced Triplet refractors are truly diffraction-limited at .25PV or better. As a privilege of ownership, those who wish to obtain a copy of their interferometric data can request it up to 90 days after registration of their ED Triplet telescope by contacting the Explore Scientific Customer Service Department.

2" 99% Reflective Dielectric-Coated Diagonal


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 2", 99% Reflective, Dielectric-Coated Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment.

Deluxe Two-Speed Focuser

On prestine nights of steady seeing, Saturn's Rings can forever affect the hearts and minds of almost anyone who lays eyes on them. It's nights like these that astronomers like to set up their refractors and push the magnification to the limits, not only to see the magnificence of the planet at greater scale but to really test the optical and mechanical quality of the telescope.

Many telescopes are only supplied with a standard single-speed 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 Series, a 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.

EMD Coatings

EMD (Enhanced Multi-layer Deposition) Coatings eliminates light scatter and maintains high image contrast. This proprietary coating is applied to all Explore Scientific lenses in multiple layers for added durability.

Contrast is further enhanced by the installation of multiple baffles in the optical tube that mask and deflect unwanted stray light.
