Celestron PWI Telescope Control Software

Celestron and PlaneWave Instruments have joined forces to develop specialized telescope control software that is now included with all new Celestron computerized telescope mounts. Celestron PWI (CPWI) Telescope Control Software unleashes the full pointing accuracy of your new Celestron computerized telescope.

With any one of three connection methods from your PC to the mount, CPWI’s telescope control and Sky Viewer display makes selecting your target easy. You can find all your favorite deep sky objects in CPWI’s extensive object database. For even more choices, we’ve linked CPWI to the online SIMBAD astronomical database, which contains more than 10 million celestial objects!

CPWI employs PointXP mount modeling, which accepts numerous star alignment points for superior pointing accuracy. PointXP (the same technology found in our StarSense AutoAlign accessory) goes beyond the pointing capability of a traditional hand control. By adding multiple star alignment points, CPWI accounts for various types of alignment errors, including instrument flexure. The result is the best possible pointing accuracy for your Celestron telescope.
