Celestron's Reputation
Celestron is a world leader in computerized telescope design and engineering
innovation
Using your NexStar i with the Computerized Hand Control gives you:
40,000+ object database– The expanded, programmable user database includes
the complete Messier, NGC, IC and Caldwell catalogs. Customized lists of all
the best galaxies, nebulae and other deep-sky objects. Room for hundreds of
user defined objects.
Quick Align – An easy way to get the altazimuth mount tracking without
actually aligning on two stars.
Hibernate – This power saving device allows you to power down the telescope
without losing your alignment. The optional CN-16 GPS accessory must be
connected. All you have to do is enter the correct time. Hibernate allows
you to look for planets in the daytime after having used the telescope the
night before or to observe night after night without having to re-align.
Database Filter Limits – User-defined so that only objects visible above the
horizon are displayed on the hand control.
Use the Power and Accuracy of GPS Satellites to Align Your Telescope with
the Optional CN-16 GPS Accessory (#93963). Plug this 16-channel GPS module
into your telescope’s drive base port to link up and automatically download
information from one of many global positioning satellites. Controlled with
the NexStar computerized hand control, the CN-16 will greatly improve the
accuracy of your star alignments by locating north and levelling the optical
tube with more precision than can be done by hand.
