COMSOFT was founded in 1990 as a software consulting company providing telescope control and satellite tracking services to the amateur and professional astronomical community. Based in Tucson Arizona, COMSOFT is in close contact with professional and amateur astronomers alike in what is considered the "Astronomical Capital of the World." Currently COMSOFT has two mature commercial software products, a control system called PC-TCS™ for equatorial mounted telescopes and SATPRO™ - an earth orbiting satellite tracking program which can be used in conjunction with PC-TCS™ to accurately track earth orbiting targets. Since 1990 COMSOFT has installed over 40 telescope control systems world wide. Clients range from State Universities and Government Institutions to advanced amateurs desiring state of the art "Observatory Class" telescope control at a moderate price. Several telescope manufacturers currently use PC-TCS™ as their preferred control system for their products. PC-TCS™, our primary software product, is robust and comprehensive in scope and has continued to evolve in the last 5 years to meet every need of both professional and advanced amateur astronomical observing programs. We even use PC-TCS ourselves - PC-TCS is running a Celestron C-14 telescope on a custom 20M equatorial mount furnished by Optomechanics Research, Inc. at our offices in Tucson Arizona. Come by and see the best control system available for large or small equatorial telescopes.
