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 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 Refractor 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 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. The compact refractor telescope optical tube measures just 15" long and weighs 2.55 lbs. for easy portability and storage. In fact, the entire Orion CT80 80mm Compact Equatorial Refractor Telescope setup, including equatorial mount, tripod and 3.25 lb. counterweight weighs just 15.05 lbs.

Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.
Beginner Level - Suited for a wide range of uses, these products are simple to operate and set up. Some initial assembly may be required depending on the type of product. Optical instruments with this rating will have very good optical and mechanical quality. Great for families, young people, and folks who don't want to mess with equipment and complexity. Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended.
Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.
Advanced Level - These products provide the best performance but may require more skill to master and appreciate. Optical instruments with this rating have exceptionally fine optics and mechanics. Some are easy to use but might be on the large or heavy side. Some are intended for specialized uses. These products will appeal to the more technically inclined. Referring to the manual is highly recommended.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.
Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.
