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.

TPoint for Windows is telescope analysis and pointing correction software that identifies, quantifies and automatically compensates for systematic errors in goto telescopes. It can also quantify the polar alignment of your equatorial mount, even when the celestial pole is not visible. Here’s how TPoint works. You collect “pointing data” (either manually or automated) by slewing the telescope to a set of stars using TheSky6, and then recording the pointing error at each position. TPoint uses this data to create a statistical model that automatically corrects repeatable errors each time the telescope is slewed. With TPoint, you achieve better pointing accuracy and spend less time centering objects and more time observing. Visit the TPoint Information  Site to learn more.
