  • Compact 22.5″ length and light 12.7 lb. assembled weight doesn’t require an enormous mount
  • Includes two heavy-duty hinged tube rings, 8×50 finder scope, dovetail mounting bar, and more

Our 6 inch aperture imaging reflector is loaded with useful features useful features to help you capture high-resolution images of the night sky. With very fast f/4 optics and 94% reflectivity coatings, the Orion 6 inch Newtonian Astrograph will help you acquire outstanding high-resolution images of deep-sky objects with delightfully short exposure times so you can get great results in less time. What’s more, this compact imaging specialist is conveniently lightweight at just 12.7 lbs., so it doesn’t require a huge mount to support it.

Its 6 inch parabolic primary mirror has 610mm of focal length, making the fast f/4 Newtonian an ideal wide-field astrophotography telescope. A substantial 63mm minor axis secondary mirror provides excellent field illumination to CCD and DSLR cameras for efficient astrophotography performance. Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings with a protective silicon dioxide (quartz) overcoat.

To optimize contrast and avoid off-axis light intrusion near the front of the telescope, the dual-speed 2 inch linear-bearing design Crayford focuser has been installed a full 7 inch back from the front of the compact 22.5 inch long reflector optical tube. For consistent results every night, an Orion-exclusive steel reinforcing plate underneath the focuser eliminates flexure, even with heavy cameras and other imaging gear attached. As with any fast Newtonian reflector telescope, an optional coma corrector is recommended to eliminate inherent coma for optimized imaging performance.

Orion 10087 EON 115mm ED Triplet Apochromatic Refractor Optical Tube Assembly (White)

    This fits your .
  • Make sure this fits by entering your model number.

  • A beautifully constructed, 115mm (4.5 inch) aperture triplet ED apochromatic ideal for both astrophotography and serious visual observations
  • Fully multi-coated, three-lens ED optics and versatile f/7.0 focal ratio yields high-contrast images with excellent color correction and sharpness
  • Rock-solid, rotatable 3 inch dual-speed (11:1) Crayford focuser provides precise focus control and stable support of imaging accessories
  • Includes two split-clamp tube rings, narrow dovetail bar, thread-on metal objective cap, and a hard case with a custom die-cut foam insert for protection during transport and storage
  • Relatively lightweight 15.2 lb. optical tube can be stably supported by medium-size equatorial mounts

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 description

Whoever coined the phrase “big things come in small packages”, would have definitely applied that expression to our new StarMax 90 TableTop Telescope. This ultra-compact Maksutov-Cassegrain (Mak-Cass) gives surprisingly big views for an instrument of its modest size, making it an elegant first telescope or a great grab-and-go second telescope! The long, 1250mm (f/13.8) focal length gives the StarMax 90 TableTop some serious magnifying power – the included 25mm and 10mm 1.25″ eyepieces yield powers of 50x and 125x, respectively. It collects over 25% more light than its GoScope 80 cousin, and up to 225% more light than a 60mm refractor telescope. So you’ll be able to enjoy planetary delights such as lunar landscapes, Saturn’s rings and Jupiter’s moons. As you scan the Milky Way, you”l also be able to pull in some open and globular star clusters, as well as a nebula or two. The tube assembly of the StarMax 90mm TableTop Mak-Cass Telescope is attached to a stable swivel base, via a quick-release dovetail mount with adjustable altitude tension. The tube can easily be removed from the base and mounted on an optional photo tripod. The small swivel base itself can also be mounted on a camera tripod with a 3/8″ screw. A red-dot view finder, internal focuser (which moves the primary lens back and forth) and included 90-degree correct image diagonal round out the features of this compact, yet surprisingly capable, Mak-Cass telescope.
