Celestron Telescope AC 90/910 AZ GoTo Astro Fi 90

The Celestron Astro Fi 90/910 is a smart refractor telescope for beginners seeking ease of use and reliable performance. Thanks to built-in WiFi and intuitive control via the SkyPortal app, manual alignment is a thing of the past. The telescope features Celestron’s SkyAlign system, which simplifies alignment: simply point to three bright celestial objects, and the software determines your exact position without needing to know their names.

With a large 90 mm aperture and 910 mm focal length, this achromatic refractor delivers sharp images of the moon, planets, and bright deep-sky objects. The telescope supports magnifications up to 180x and has an f/10.1 focal ratio, ideal for detailed observation. The optics feature aluminum and SiO₂ coatings for bright, high-contrast images.

The mount is azimuthal and single-arm, providing excellent support for the light refractor tube. The telescope is quick to set up and easy to transport thanks to its compact design and aluminum tripod. The SkyPortal app not only shows the current night sky but also provides extensive background information about objects, including images and audio clips (in English). The database contains over 120,000 objects.
