• With exceptional optics, top-notch features, /*C*and*C*/ beautiful fit /*C*and*C*/ finish, the Orion EON 115mm ED Triplet refractor telescope offers wide-field observers /*C*and*C*/ astrophotographers an impeccably crafted, true-color instrument at a great price. We've updated the previous award-winning design with an even more robust focuser, /*C*and*C*/ streamlined the tube rings /*C*and*C*/ dovetail bar. From front to back, this is a beautifully well-crafted /*C*and*C*/ rock-solid design.

  Fast Scope with Generous Aperture

  This premium refractor telescope's generous, 115mm (4.5') 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 /*C*or*C*/ 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, /*C*and*C*/ multiple internal knife-edge baffles eliminate off-axis reflections /*C*and*C*/ glare to ensure excellent contrast.

  Heavy-Duty 2.5' Rack /*C*and*C*/ Pinion Focuser

  At the back end of the EON 115mm Triplet ED, you'll find a new heavy-duty 2.5' dual-speed Rack-and-pinion focuser with precise 10:1 fine focus control. The focuser features an Orion finder scope base for attachment of any Orion reflex sight /*C*or*C*/ finder scope if desired. The big focuser's 2.5' drawtube sports an engraved millimeter scale to aid in focus point repeatability, /*C*and*C*/ features a focus-lock thumbscrew, both of which are especially useful for astrophotography. Both the 2' accessory collar on the focuser drawtube /*C*and*C*/ the 1.25' adapter feature non-marring brass compression rings /*C*and*C*/ a robust 'twist-lock' style mechanism for securely clamping down onto the diagonal /*C*or*C*/ camera nosepiece.

  Compact Wide-Field Performer

  Not only is the EON 115mm ED Refractor a great wide-field performer, it's also conveniently compact /*C*and*C*/ measures just 28' with its sliding dew shield retracted for easy transport /*C*and*C*/ storage in the included foam-lined hard carry case. Unlike heavier, bulkier astrophotography telescopes, the relatively lightweight, 15 lb. EON 115mm optical tube needs only a medium-sized equatorial mount to support it.

  Finder Dovetail Base as a Guide Scope

  The EON 115mm refractor's finder dovetail base can also be used for optional guide scopes such as one of our Mini Guide Scopes. A slip-fit metal objective lens cap, a narrow 'Vixen-style' dovetail mounting bar /*C*and*C*/ two heavy-duty hinged tube rings with multiple, pre-drilled /*C*and*C*/ tapped holes along the top /*C*and*C*/ bottom are included.

  If you're looking for an exquisitely constructed 'apo' refractor that can achieve amazing results for both astrophotography /*C*and*C*/ serious visual observing, the versatile Orion EON 115mm ED Triplet is an ideal choice.
