SkyCruiser is software running under the Android operating system, developed for the purpose of controlling Celestron Nexstar and compatible telescopes wirelessly employing Bluetooth® and GPS.
After mount alignment which requires the hand control, SkyCruiser basically replaces the hand control of the telescope mount with wireless control.
The software requires familiarity with the use of the connected telescope mount, its hand control, Android smart phone and basic astronomy.

Please be sure to read the manual before you fumble in the dark:
(also bundled in the application package).
