15 arc-seconds as a standard. Greater pointing accuracy, using higher resolution encoders, is available at additional cost. GPS system provides continual precise timing for computer control. Latitude and longitude GPS data can be used for systems on a mobile platform. Kinematical mirror support system.
Servo motors drive the main axes of the telescopes.
These control systems have been refined through years of research, development, and practical application and are proven to be very powerful and effective. You can automatically control all the actions necessary to operate your observatory to take hundreds of CCD camera images for various research projects during an evening. The computer is provided as an integral part of the control system. Control Hardware and Electronics Our drive control system includes incremental encoders, limit switches, and home switches on the RA and DEC axes. The focusing mechanism moves the secondary mirror very precisely with a stepper motor and provides a large amount of back focus.
