The latest option for the Vixen GP2 and GPD2 mounts and most Chinese clone mounts is the new Starbook S, a GoTo controller with built-in, interactive star chart, that shows you exactly where the telescope is pointing and displays “what’s up” right now.
The included (and upgradeable) software contains a 22,000 object database giving the user an endless variety of objects to view. Included are drop-down menus listing different categories of celestial objects, including Stars, Planets, Messier, NGC and other famous objects. Each sub menu only lists the objects that are available to be viewed at that time. This eliminates the frustration of other GOTO systems that don’t tell you the object is below the horizon until after you have selected it.
With the Vixen Starbook you will spend more time viewing and less time searching.
