Description

The ED80 Essential Series Air-Spaced Triplet Refractor is a true apochromatic telescope that reveals celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog. 

Offering true diffraction-limited optics with genuine HOYA FCD1 ED glass, the ED80 is the perfect size to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer deposition coatings on all optical surfaces.

Although it is a standout telescope on its own, the 80mm also is compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties. The telescope tube's outside diameter is 91 mm.

Explore Scientific 2" rack-and-pinion focuser comes with 2 extension tubes. Explore Scientific Hybrid Finder Scope Base installed on scope. (Finder scope not included.)

When I gazed into the eyepiece, the four members of the Double Double showed surprisingly well, leaving me to wonder what this scope might do on a night of optimal seeing conditions. I have no doubt the ED80 can achieve its advertised resolving limit of 1.45”…. Small and portable, it’s an ideal grab-and-go telescope. It’s also extremely versatile, able to capture wide-field views spanning several degrees while also providing the high power punch to tease out lunar and planetary detail and split close double stars…"
