Order Info

Our SiTech Controller seamlessly controls your telescope system to track/search celestial objects.



  • Point your scope to the NCP or SCP and turn on the power, the scope will start to track precisely. Nothing else, not even a handpad is required; it is as simple as this.
  • Superior local search function. A spiral search will either miss sky, or has too much overlapping sky. SiTech local search feature is a series of circles, each larger than the other. It remains a true circle regardless of your altitude or declination. You can pause, reverse, speed up, slow down, during the search, and you have two radius choices, all from the handpad.
  • Superior and precision servo motors drive system with state of art drive train.
  • Professional grade Sidereal Technology controller combined with the optional Nexus DSC Pro will enable you to use virtually any planetarium software seamlessly on WiFi-enabled devices such as iPad, iPhones, Apple Computers, Windows based PC/tablet. Kindle Fire, and Android device.
  • SiTech has a powerful script feature. You can pan the Lunar terminator using relative pan commands, Pan the Veil Nebula with absolute pans, even write your name with starlight, etc. Making the scripts is as easy as moving your scope (or the virtual scope during the day), and clicking on various options.
  • For advanced imagining users, SiTechExe (running on a PC) offers an extremely powerful and unique PointXP telescope modeling software by Dave Rowe. PointXP takes a series of "Calibration Stars" to performs some very complex transformations, Gauss-Jordan, Partial Derivatives; and does a fine job in correcting for many telescope mounting errors and mount flexture and can increase the pointing accuracy by a factor of up to 10!
  • SiTech provides the Auto Guider port on an optional wireless handpad receiver. This is an industry standard connector, where you can plug an SBIG or other standard auto-guider. The autoguiding works extremely well, because of the “Equal Area Guiding,” Backlash compensation, and instantaneous corrections. The auto-guider inputs are acted upon within milliseconds.

  • Built in SiTech ASCOM software support for auto focuser and de-rotator via a second SiTech controller. You will use the “Azimuth” channel of the second SiTech controller for the focus motor, and the “Altitude” channel of the second controller for a field de-rotator motor.
  • Interface with any ASCOM Compliant Planetarium programs and telescope control routines inside CCD imaging programs.
    • Earth Centered Universe (ECU)
    • TheSky™
    • Cartes du Ciel
    • MegaStar
  • ARGO NAVIS™ and Sky Commander are supported; but are not required.
  • Easy Plug-n-Play self-installation, and No drilling is required! Just tighten a few screws, and you are ready to GOTO. It will likely take more than a few minutes, but it will NOT be hours or days to install our GOTO system.
  • The GoTo package includes: SiTech Dual Servo Telescope Controller I and Wired Handpad; 2 servo motors and gear boxes; all necessary accessories (cables, adapter plates, screws, etc.); a 8192 azimuth and altitude encoders. The iPad, SkyFi controller and the SkySafari software are NOT included. Please note that if there is no RS232 (serial) port on your computer, then you must have a USB to RS232 Adapter Cable, which is not provided.
