TPoint Telescope Pointing Analysis Add On

Finding objects in the night sky is difficult enough.  The optional TPoint Add On to TheSkyX improves your telescope's pointing accuracy just like professional observatories.




The optional TPoint Add On to TheSkyX Serious Astronomer Edition is telescope analysis and pointing correction software that identifies, quantifies and automatically compensates for systematic errors in "go to" telescopes.  It can also quantify the polar alignment of your equatorial mount, even when the celestial pole is not visible.


Face it. Your fancy "goto" telescope doesn't always place objects in the eyepiece, or on your CCD detector. Why? Because every telescope suffers from inherent errors that degrade pointing accuracy. Even telescopes like the Keck, Gemini, and Anglo-Australian Observatory have less than perfect pointing.  For years, professional astronomers at these and other observatories have relied on TPoint to improve the pointing of their telescopes.  Now you too can join the ranks of the pros by employing TPoint to make your telescope point more accurately.

How it works.

You collect “pointing data” (either manually or automated) by slewing the telescope to a set of stars using TheSkyX and then recording the pointing error at each position (a single button click). TPoint uses this data to create a statistical model that automatically corrects repeatable errors each time the telescope is slewed.


With the TPoint Add On, you achieve better pointing accuracy and spend less time centering objects and more time observing.

What's new with TPoint.

TPoint is now an optional integral component of TheSkyX.  There's no separate installer, no separate application.  Just click the TPoint Add On command from TheSkyX menu.

What's Not New

As with TheSkyX, every feature from TPoint for Windows has been included in the TPoint Add On.  Only better and easier.



New Features in the Optional TPoint Add On


  • TPoint functionality is completely integrated with TheSkyX

Select the TPoint Add On command from the TheSkyX's Telescope menu.  No separate software to install.  


  • Support for Mac OS and Windows



  • 90-day trial period



Try the fully-operational TPoint Add On for 90 days.


  • Completely new, easier to use interface



  • Modeling results are shown on the TPoint window and directly on TheSkyX's Telescope window


  • Super Model


Take the Guess Work Out of Generating Pointing Models

TPoint's Super Model feature automatically determines the best pointing model for your imaging system.  


A simple button click performs an extensive statistical analysis of your mount's pointing calibration data and converges on the optimal and most precise pointing model using all the processing power of your computer.
