Free yourself and your astronomy sessions from cords with Celestron's Astro Fi 102mm f/13 Maksutov-Cassegrain Telescope. It utilizes an integrated antenna to emit a local Wi-Fi signal so you can control the mount via direct wireless connection with Android and iOS smartphones and tablets running the free SkyPortal app.

Optically, the scope sports a design similar to the more common Schmidt configuration, but this Maksutov variation exchanges the front corrector plate for a convex meniscus lens, which eliminates the need for periodic collimation. Additionally, the nature of the lens requires a smaller secondary mirror that 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 and planetary observation, with the resolution required for splitting binary stars and separating star clusters. This complete observation rig includes the optical tube assembly (OTA), a motorized mount controlled by the app, 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 multiple alignment procedures, it can automatically find objects in the night sky, and it offers guided tours of the most interesting objects overhead on any given night with select audio commentary including histories, mythologies, and NASA images. The mount runs on eight user-supplied AA batteries, and the entire rig assembles and breaks down without the need for tools so you spend less time setting up and more time observing.

In the absence of battery or power adapter, can this telescope still be adjusted manually if required ?
Asked by: Manish
Although the Astro Fi can be moved manually by hand in its altitude axis, it cannot be moved manually in its azimuth axis. A battery or power adapter is required.

What exactly can you see in detail with a telescope like this? Do you just see the moon in more detail, or can you actually see a bit more of the solar system? Sorry, unexperienced person here.
Asked by: Don
From the city, you can easily view craters on the moon, Saturn's rings, and even Jupiter's cloud bands and four of its brightest moons through the Astro Fi 102. From a dark sky site, the telescope will reveal nebulae, galaxies, globular and open star clusters and much more. Light pollution will be your biggest obstacle.

Is the dc jack that is on the telescope is of non-standard length ? I couldn't fit any of the existing 12v dc power adapters that I had. Do telescopes have a different jack length ? Is there a way I can use the standard 12v dc power supply with it (using some connectors perhaps ?) . Standard dc jack length is 10mm, while this telescope requires around 13mm. Is that correct ?
Asked by: Manish

Where I view stars there is no internet or cellular service. Can this telescope still track without an internet connection?
Asked by: john
The Astro Fi 102mm telescope emits its own WiFi local signal which can be received by your smart device. You will need to download Celestron's SkyPortal app to align and control the telescope. Once aligned, tracking is automatic, although there are other tracking rates available.
