If you're looking for a great starter telescope, but are worried about taking up too much space, Orion has the answer! Our CT80 EQ refractor packs a lot of stargazing performance into a compact telescope setup.

The versatile Orion CT80 EQ 80mm Refractor Telescope combines a wide-field refractor telescope with a stable equatorial (EQ) mount and adjustable tripod. The telescope's 80mm (3.15") aperture, f/5 objective lens is larger than lenses found in most typical starter scopes, which means you'll enjoy brighter views of everything you see. The CT80 optics are fully coated with anti-reflection coatings for clear, sharply defined views. Internal knife-edge baffles help optimize contrast by preventing off-axis reflections. The CT80 EQ Compact Refractor will amaze the whole family with wide-field views of the Moon, planets, and even bright nebulas and star clusters.

The included EQ-1C equatorial mount is specifically designed for convenient stargazing. The telescope mount is equipped with handy slow-motion controls which allow easy manual tracking of celestial objects as they appear to move across the sky. The equatorial mount head sits atop a sturdy black metal tripod with extendable, cylindrical legs which can be adjusted easily to set the telescope at a comfortable height. An optional EQ-1CM DC Drive (sold separately) can be added at any time to motorize the EQ-1C mount for hands-free tracking of celestial objects.

The CT80 EQ 80mm Refractor Telescope sports a 1.25" rack-and-pinion focuser, and two 1.25" eyepieces are included. The included 25mm Kellner eyepiece provides a 16-power view through the telescope, while the included 10mm Plossl ocular boosts magnification up to 40x for closer looks. An included 1.25" star diagonal places inserted eyepieces at a comfortable angle for stargazing. You can use other 1.25" eyepieces or Barlow lenses with the CT80 EQ Refractor Telescope to achieve different magnifications (Barlow lenses and additional eyepieces sold separately). An included red-dot sight with two brightness settings helps aim the telescope at interesting objects. This special kit includes the Orion Moon Map, Orion Moon Fllter, Orion RedBeam Mini Flashlight and the Orion Star Target Planisphere.

The entire Orion CT80 80mm Compact Equatorial Refractor Telescope setup, including equatorial mount, tripod and 3.25 lb. counterweight weighs just 15.05 lbs.

Moon Map

Use the Orion MoonMap 260 to learn more about the lunar features you see in the telescope.

With locations and names of over 260 features on the Moon such as craters, mountains, valleys, "seas" and more, the included Orion MoonMap 260 is a great tool for beginning astronomers. This detailed map will even show you where various spacecraft have landed on the Moon's surface! The whole family will enjoy looking at the Moon with the telescope, then using the MoonMap 260 to learn the names of the craters and other features observed.

Reduce glare and boost contrast so you can see enjoy more detailed views of lunar surface features with this Orion E-Series 13% Transmission Moon Filter.

Blocks excessively bright glare to provide a more comfortable view of the Moon's surface. Neutral density filter will not alter the natural color of the Moon. Telescope eyepiece filter transmits only 13% of the incoming light, improving contrast and detail.

Read star charts, look inside your accessory case, or find your way around the telescope in the dark with the Orion RedBeam Mini LED flashlight.

Very compact size - doesn't take up much room in your accessory case, and can easily fit in a pocket. Will not harm your night vision like a white flashlight can.

An easy to use accessory that helps you learn the location of constellations, bright stars, and many deep-sky objects such as nebulas, galaxies, and star clusters.

Simply dial in the date and time across the top, and Star Target shows you the sky overhead. Designed for use within 30-degree North and 50-degree North latitudes regardless of calendar year - shows locations of 100 star clusters, nebulas and galaxies for viewing with binoculars or telescope.
