Upgradeable Version 4 Hand Control
Update - this hand control has been replaced by the
In January 2006, Celestron began offering the version 4 user-upgradeable hand control for owners of older telescopes. This hand control was introduced with firmware version 4 and is compatible with all NexStar GPS, CPC, LCM, i Series, SLT, GT, StarSeeker, Tasco StarGuide, CGE, CGE Pro, CGEM and AS-GT telescopes. The only NexStars this hand control will not work with are the original NexStar 5/8 (non-i Series).

The following "models" of hand control are available with the correct firmware for the various telescope series:
Originally, these hand controls were only available directly from Celestron. The cost was $150 for a replacement hand control or $75 if you traded-in your old hand control. As of May 2007, they discontinued this offer. The hand control was then available for direct purchase from most Celestron dealers.
