Celestron's NexStar+ EQ Hand Controller is the brain for their Advanced VX, CGEM, CGEM II, CGEM DX, CGX, and CGE Pro motorized and computer-controlled equatorial telescope mounts. This tethered hand box connects to, and is powered by, the mount via a coiled cord. Once connected, it puts a 40,000-object database in the palm of your hand and helps you to explore near and deep-sky celestial subjects from the Moon and planets to galaxies, nebulae, and star clusters. If you're not sure what is overhead, simply use the Tour Mode and the NexStar+ will show you the best objects based on your current location, date, and time.
Multiple set-up and alignment systems help to get you observing faster, while the 3 rates ensure accurate tracking all night with little correction required. Backlash compensation and Permanent Periodic Error Correction (PPEC) help to increase the smoothness, precision, and accuracy of tracking. Its 2-line/16-character LCD screen gives you access to the intuitive menu-driven user-interface for fast navigation of the sub-menus while showing you all information in red to preserve night-adjusted vision. Variable brightness levels for the screen and button backlight ensure comfortable use.
