The Sky Tour object locator adds "brains" to your Tele Vue mount. With its exclusive Lorenzin 2000+ database and refinements such as dimmable red light display, backlit button names, 10-character speed-adjustable scrolling display, and advanced "identify" capability, Sky Tour brings the hand-held computer to a new feature/performance level -- a Tele Vue level of convenience and ease of use. When Sky Tour is added to Tele Vue mounts, the total system is simple enough to encourage beginners, yet deep enough for experts to maintain a lifetime of observing enthusiasm. For the amateur telescope maker, you can purchase the Sky Tour computer and encoders for integration into most any telescope mount. The Sky Tour computer can be initialized and custom calibrated for the following types of mounts: altitude-azimuth, German equatorial, fork mount, and equatorial table.
