Celestron’s Astro Fi 90mm f/10 GoTo Refractor Telescope utilizes an integrated antenna to emit a local WiFi signal so you can control the mount via Android and iOS smartphones and tablets running the free SkyPortal app. Optically, the scope sports a 90mm aperture, a long 910mm focal length, and fully coated optics so you can make detailed observations of the Moon, and view planets, comets, and satellites. This complete observation rig includes the optical tube assembly, a motorized mount, an aluminum tripod, two eyepieces, a 90° diagonal, and a red-dot finder.

The OTA is mounted on a single-arm motorized alt-az mount. Guiding the mount is the SkyPortal app. Packed with over 120,000 objects, it is designed to help users get set up and start observing quickly. The app offers alignment aids that automatically find objects in the night sky, build customized guided tours, has automatic tracking rates for near and deep-sky objects, and multiple slew speeds. Supporting the OTA and mount is an aluminum adjustable-height tripod. The entire rig assembles and breaks down without the need for tools, so you can set it up easy and start observing sooner.
