The NexGuide Autoguider from Celestron is a stand-alone system that eliminates the necessity of tethering it to a laptop computer for finding or tracking your celestial targets with a motorized alt-az or equatorial mount. A Aptina MT9V034C12STM CMOS sensor allows the tracking of even faint stars, and the larger 5.6x4.7mm chip size provides more area for locating and keeping the guide star on the chip. Automatic calibration of each axis and automatic setting guide rate parameters make the NexGuide easy to use and very precise.
A standard 1.25" ring is included to fit the most common size drawtube and allows the use of any eyepiece for focusing and centering, and a 9-button hand control provides quick and easy access to the navigation menus. It runs on four user-supplied D-cell batteries to power it when you're off the grid, and all that is required is for the mount or GoTo hand controller to have a ST-4 autoguider port to plug the unit into.
