For the dedicated visual observer or astrophotographer seeking a top-of-the-line instrument, the Orion EON 130mm Triplet ED Apochromatic Refractor should be on your short list of candidates. This exquisite telescope features premium optical performance and a high-end fit and finish. From front to back, this is truly an awe-inspiring refractor. At the front end, you’ll find a three-element, air-spaced lens assembly of 130mm (5.1 inch) aperture, with one element of FPL-51 ED glass for superb color correction and sharpness. The EON 130mm Triplet is a wonderfully versatile telescope for both deep-sky and solar system imaging or stargazing since it has plenty of image scale for smaller targets and a moderately fast f/7.0 focal ratio. All air-to-glass lens surfaces bear anti-reflection multi-coatings for superior light transmission. Contrast is equally rich thanks to a retractable glare-blocking dew shield, blackened lens edges and five internal knife-edge baffles that prevent off-axis reflections of incoming light. At the back end of the EON 130mm Triplet ED, you’ll find a heavy-duty, 3 inch, dual-speed, rotatable Crayford focuser with precise 11:1 fine-focus control. The big 3 inch drawtube sports an engraved millimeter scale to aid in focus point repeatability. The EON 130mm Triplet comes with two substantial, split-clamp tube rings and a hard case with custom foam interior. The tube rings feature multiple 1/4 inch-20 threaded sockets for attachment of mounting plates or other accessories.

Product description

Our AstroView 120ST is a compact, rich-field refractor designed for observation of nebular clouds, star clusters, and even galaxies. Its multi-coated achromatic objective lens has a 120mm (4.7″) clear aperture and has a focal length of just 600mm (f/5). Compared to our standard 120mm AstroView (f/8.3), that translates to a 66% wider field of view for any given eyepiece. The fast f/5 optical system also makes it an excellent telescope for astrophotography. The 120ST has a well-baffled optical tube to ensure good contrast. The cast-metal, 2″ rack-and-pinion focuser accommodates either both 1.25″ and 2″ diagonals. The AstroView equatorial mount with adjustable aluminum tripod provides a sturdy platform for precision tracking. Add an optional EQ-3M electronic drive for fully automatic tracking. One-year limited warranty.

With exceptional optics, top-notch features and beautiful fit and finish, the Orion EON 115mm ED Triplet refractor telescope offers wide-field observers and astrophotography’s an impeccably crafted, true-color instrument at a great price. This premium refractor telescope’s generous, 115mm (4.5 inch) aperture collects ample light from faint deep-sky objects to provide crisp images with excellent color correction by virtue of the element of FK-61 extra-low dispersion (ED) optical glass in its air-spaced triplet objective lens. The apochromatic refractor’s medium 805mm focal length gives it a fairly fast, f/7.0 f-ratio which performs exceptionally well for wide-field visual use or deep-sky astrophotography. Multilayer anti-reflection coatings on every air-to-glass lens surface maximizes light transmission; while an extendable dew shield, blackened lens edges, and multiple internal knife-edge baffles eliminate off-axis reflections and glare to ensure excellent contrast. A massive, 3 inch dual-speed (11:1) Crayford focuser provides precise, backlash-free focus control and easily supports heavy astrophotography gear. The EON 115mm ED’s focuser can be rotated in two places, allowing camera framing to be set independently from your preferred positioning of the telescope focus knobs. Not only is the EON 115mm ED Refractor a great wide-field performer, it’s also conveniently compact and measures just 27.75 inch with its sliding dew shield retracted for easy transport and storage in the included 33 inch long foam-lined hard carry case. The EON 115mm refractor telescope features a dovetail finder scope base for use of optional aiming devices or Mini Guide Scopes. A thread-on metal objective lens cap, a narrow Vixen-style dovetail mounting bar and two heavy-duty hinged tube rings with multiple, pre-drilled and tapped M6 holes along the top and bottom are included.

This short focal length refractor telescope gives wonderfully wide views of the night sky! You do not need a big, bulky telescope to enjoy backyard astronomy. Our potent little Orion Observer 80ST Equatorial Refractor Telescope proves otherwise. Compact and hassle free, it’s easy to take outside and set up, and easy to bring in when you’re done.

This versatile telescope’s 80mm-aperture objective lens has a short focal length of 400mm (f/5), which makes the Observer 80ST extremely portable and compact. Thanks to the telescope’s fast f/5 focal ratio, bright, wide-field views of the stars and deep-space objects are the Observer 80ST’s forte!

Tracking celestial objects while viewing them in the Observer 80ST telescope is a cinch with the smooth and stable EQ-1B equatorial mount and tripod. The mount is equipped with dual slow motion controls for easy manual tracking of objects in the night sky.

The Observer 80ST refractor telescope comes with a reflex sight, 90-degree diagonal (1.25″), and 10mm and 25mm Kellner 1.25″ telescope eyepieces with anti-reflection coating. This pint-sized refractor also includes the useful MoonMap 260 to help you identify interesting lunar features you can see in the telescope. A niftier grab-and-go scope you will not find!
