Plug SkyHub2S directly into your Windows, Mac, or Linux computer with a USB cable — no wireless setup, no dropouts, and the host computer powers the unit so you don't need a battery pack. A built-in mode switch lets you disable wireless for clean, interference-free USB operation.
Point your scope to any star, touch the same star on Sky Safari to complete a one-star alignment. Then touch any target on screen and move your scope until the position mark meets the target — done! Optionally perform a two-star alignment at any time for better accuracy.
