Celestron Inspire 100AZ Refractor Telescope

Full review

The Celestron Inspire 100AZ is a refractor telescope designed to make astronomy approachable for beginners while still offering enough optical quality to satisfy hobbyists who want to grow into the pastime. It features a 100mm aperture achromatic lens paired with a 660mm focal length, giving it a focal ratio of f/6.6 that balances wide-field views of star clusters and nebulae with enough magnification for lunar and planetary observation. The fully coated glass optics help deliver crisp, high-contrast images while minimizing chromatic aberration, and the sturdy altazimuth mount allows for smooth, intuitive up-down and left-right movements that make tracking celestial objects simple, even for someone who has never used a telescope before.

What sets the Inspire 100AZ apart from many entry-level scopes is its thoughtful design details aimed at making the observing experience more engaging and educational. The telescope includes a built-in smartphone adapter integrated directly into the focuser, allowing users to capture images of the Moon or bright planets without needing separate mounting hardware. It also comes with a unique innovation Celestron calls the "LED flashlight" housed in the front lens cap, which doubles as a red flashlight for preserving night vision while adjusting equipment in the dark. Two interchangeable eyepieces, a 20mm and a 10mm, are included to provide both wide-field and higher-magnification viewing options right out of the box, and a rack-and-pinion focuser ensures precise focusing adjustments.

Constructed with a lightweight yet stable tripod and a sturdy accessory tray, the Celestron Inspire 100AZ is easy to transport and set up, making it a practical choice for backyard stargazing sessions or trips to darker skies away from city lights. Its aluminum tube and tripod legs keep the overall weight manageable without sacrificing durability, and the no-tool assembly process means users can be observing within minutes of unboxing. Whether aimed at the craters of the Moon, the rings of Saturn, or the cloud bands of Jupiter, this telescope delivers a rewarding introduction to visual astronomy, combining solid optical performance with user-friendly features that encourage curiosity and long-term engagement with the hobby.
