Celestron AstroMaster 102AZ Refractor

Celestron AstroMaster 102AZ 102mm f/6.5 Refractor Telescope (#22065)

A no-fuss refractor that’s as comfortable under the stars as it is during daylight hours.

Whether you’re scanning lunar craters, chasing Jupiter’s moons, or watching wildlife across a lake, the Celestron AstroMaster 102AZ offers a versatile observing experience that’s easy to set up, easy to use, and a joy to look through. Its bright 4" aperture gathers ample light for serious views, while the alt-azimuth mount and upright-view optics make it equally at home for terrestrial use during the day.

Perfect for beginners and casual observers, the AstroMaster 102AZ is a grab-and-go refractor with an upgraded optical tube, sturdy tripod, and no complicated electronics to slow you down.

Wide-Field Views with Serious Aperture

The AstroMaster 102AZ uses a 102mm (4") air-spaced achromatic doublet refractor with fully coated glass optics for crisp, high-contrast views. With a 660mm focal length and moderate f/6.5 focal ratio, this scope provides bright, wide-field views that are perfect for sweeping the Milky Way, viewing open clusters like the Pleiades, or getting crisp looks at the Moon and planets.

It’s also well suited for terrestrial observation. The included 90° erect image diagonal corrects the view for right-side-up, left-to-right orientation—just like a spotting scope, but with astronomy-grade optics.

User-Friendly Mount and Setup

No tools, no alignment routines, no hassle—just extend the tripod, attach the tube, and start observing. The AstroMaster 102AZ includes a manual alt-azimuth mount with a smooth pan handle control and adjustable clutch. You can track objects across the sky or around the horizon by simply guiding the scope left, right, up, or down.

The full-height steel tripod offers adjustable height (32"–51") and a wide accessory tray to hold your eyepieces and diagonal close at hand. Despite its sturdiness, the full setup weighs just under 13 lbs, making it portable enough to take to a dark sky site or a family vacation.
