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 with 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, 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 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.
