Basic Information about the Celestron CPC Series
The biggest news regarding the new hand control is user upgradeability and the new alignment methods. Future upgrades to the hand control firmware will be available for download via the Internet and owners can apply the upgrades themselves. The new alignment methods are SkyAlign, Auto Two Star Align (first available on the NexStar 8i Special Edition), Solar System Align and One Star Align. In addition to the new alignment methods, the new hand control still has Two Star Align, EQ North/South Auto Align and EQ North/South Two Star Align. Removed since the NexStar GPS are Quick Align, Auto Align and GPS Align. See the Alignment Guides section of this web site for details on the new alignment methods.
Other notable features include a new bracket that keeps the hand control facing you during use, a new tripod, a quick-release bracket for the finderscope and an internal GPS receiver for automatic entry of date, time and location information during the alignment process.
