Editing Tpoint (section)

'''TPoint''' is [[computer]] [[software]] that implements a mathematical [[Model (abstract)|model]] of conditions leading to [[error]]s in [[telescope]] pointing and tracking. The model can then be used in a telescope control system to correct the pointing and tracking. Such errors are typically caused by [[machine|mechanical]] or [[structural]] [[wikt:defect|defects]]. For example, TPoint can analyze and compensate for systematic errors such as [[polar alignment|polar misalignment]], mechanical and optical non-orthogonality, lack of roundness in telescope mounting drive [[gear]]s, as well as for [[flexure]] of the mounting caused by [[gravity]].

TPoint is in use on the majority of professional telescopes worldwide, including among many others the [[Anglo-Australian Telescope]], [[Keck Observatory]], [[Gemini Observatory]] and the [[Large Binocular Telescope]]. It has significantly improved the performance and efficiency of telescope operation and has had an especially strong impact on the development of [[Automation|automated]] and [[robotic telescope]]s. 

TPoint is also widely used by [[amateur astronomy|amateur astronomers]]. [[Software Bisque]] distributes TPoint as an add-on to TheSkyX Serious Astronomer Edition and TheSkyX Professional; this version is used to improve the pointing on amateur telescopes.<ref name=ST-July2012>{{cite journal|last=di Cicco|first=Dennis|title=The Paramount MX|journal=Sky & Telescope|date=July 2012|volume=124|issue=1|pages=64–67|bibcode=2012S&T...124a..64D |issn=0037-6604}}</ref>
