Celestron's Astro Fi 102mm f/13 Maksutov-Cassegrain Telescope utilizes an integrated antenna to emit a local Wi-Fi signal so you can control the mount via Android and iOS smartphones and tablets running their free SkyPortal app.
Optically, the scope sports a design similar to their Schmidt cousins, but the Maksutov design exchanges the front corrector plate with a convex meniscus lens which eliminates the need for periodic collimation. Additionally, the nature of the lens requires a smaller secondary mirror which limits obstruction and increases contrast. This optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt-Cassegrain, but the optical benefits makes this an ideal scope for lunar, planetary and double-star observation. 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 set up quickly and start observing faster. The app offers align aids, automatically finds objects in the night sky; and even offers guided tours, automatic tracking rates for near and deep-sky objects, and multiple slew speeds. The mount runs on eight user-supplied AA batteries, and the entire rig assembles and breaks down without the need for tools so you set up faster and start observing sooner.
