Description
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.

Product review & video
hello ken with Orion telescope hitters and this is the Orion Aeon 115 millimeter IDI paper chromatic refractor it's a triplet so there are three lens elements up front one of them is an extra low dispersion so this features very good color correction you don't see any blue or purplish halos around bright stars as you push the power up for planetary viewing or for image taking so a very clear high contrast image free of chromatic aberration as an astro photographic lens it features an eight hundred and five millimeter focal length at f7 so it's a nice medium wide field camera lens perfect for larger deep sky objects the Orion Nebula Andromeda galaxy framing most of those big deep sky messy office would be perfect with something like this and because it's got that IDI glass you could push the power nice and high so if you want an image planets as well this this really does a good job just
