Big views in a small package—perfect for first-time stargazers and daytime explorers alike.
The Celestron PowerSeeker 80AZ Short Refractor is a compact 80mm (3.15") f/5 telescope designed to be as user-friendly as it is portable. With fully coated glass optics and a no-tool setup, it’s an ideal choice for anyone just beginning their journey into astronomy or needing a grab-and-go option for impromptu observing sessions under the stars—or daylight adventures with birds, landscapes, and wildlife.
The 80mm aperture gathers over 130 times more light than the human eye alone, giving you bright, detailed views of the Moon, planets like Jupiter and Saturn, star clusters, and even some of the brighter deep-sky objects like the Orion Nebula or the Andromeda Galaxy.
Its short 400mm focal length delivers a fast f/5 focal ratio, which translates into a wide field of view—perfect for scanning the Milky Way or capturing the full disk of the Moon. Fully coated optics enhance contrast and brightness while minimizing reflections.
From box to backyard in minutes. The PowerSeeker 80AZ requires no tools to assemble, making setup painless even for total beginners. Just attach the optical tube to the tripod, insert your diagonal and eyepiece, and you’re ready to go.
The lightweight aluminum optical tube and steel tripod keep the total weight under 6 lbs—easy to carry, pack in a car, or move around the yard as needed.
The manual alt-azimuth mount includes a slow-motion control rod, allowing for precise up/down and left/right adjustments. This makes it easier to track objects as they drift across the sky or to gently follow terrestrial subjects like birds and boats.
Celestron includes a well-rounded set of accessories to help you get the most out of every observing session:
20mm eyepiece (20x) for wide-field views of star fields, craters, and landscapes
4mm eyepiece (100x) for higher-power planetary or lunar detail
3x Barlow lens triples the magnification of either eyepiece, giving you 60x and 300x options
Erect image diagonal provides a right-side-up, correct-orientation view for comfortable terrestrial use
5x24 finderscope helps you aim the telescope with ease
Adjustable steel tripod with accessory tray offers a solid base and convenient storage for your gear
Thanks to the erect image diagonal, the PowerSeeker 80AZ pulls double duty as a daytime spotting scope. Watch wildlife at the lake in the morning and sweep the Moon’s surface at night—all with the same lightweight setup.
You’ll also receive a copy of Celestron’s Starry Night Basic Edition software, plus access to the SkyPortal app—your gateway to identifying thousands of celestial objects from your phone or tablet.
