Celestron Astromaster 102AZ Refractor Telescope

Equally at home on the horizon and under the night sky, the Celestron AstroMaster 102AZ is a refractor telescope with a 102mm aperture, 660mm focal length and f/6. 5 focal ratio on a manual alt-azimuth mount. Its upright-image 90 diagonal supports terrestrial viewing, while the fully coated all-glass optics and supplied 20mm and 10mm eyepieces provide 33x and 66x magnification for lunar, planetary and wider sky observation.

This beginner-friendly model pairs straightforward handling with a practical, no-tool setup. A pan handle control allows smooth manual pointing, and the adjustable steel tripod includes an accessory tray. The optical tube is aluminium, with a built-in red dot finder and a CG-5 dovetail bar. Celestron Starry Night Basic Edition software and the SkyPortal app are also included.

Safety information

• Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
• Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
• Never leave your optic unsupervised.
• Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
