Planewave Logo White Black Back Ground

Celestron has teamed up with PlaneWave Instruments to develop specialized telescope control software for the CGX and CGX-L mount.  PWI Telescope Control unleashes the full pointing accuracy potential of your CGX and CGX-L mount.

With a direct USB connection from your PC to the USB port on the mount, PWI’s Sky Viewer display makes for easy target selection. Or find your favorite deep sky object in PWI’s extensive object database. Beyond that, PWI links to the online SIMBAD astronomical database for even more objects.

PWI employs PointXP mount modelling, which accepts numerous star alignment points for the best possible accuracy.  PointXP (also used in StarSense AutoAlign accessory) goes beyond the pointing capability of a traditional hand control.  By adding multiple star alignment points, PWI accounts for various types of alignment errors, including instrument flexure. As a result, the overall pointing accuracy is improved.



  • PointXP mount modelling, accepts as many star points as desired to add to the pointing model
  • Co-developed with PlaneWave Instruments
  • Future updates will contain more features and improvements
  • Sky Viewer star cart makes object selection easier
  • Extensive object database, including online database
