| PC-TCS is a Personal Computer
based Telescope Control System
designed for use with moderate to large permanently mounted
astronomical telescopes. The software will run on all IBM-class
computers.
PC-TCS provides the
observer with a highly flexible battery of motion control
functions handsomely matching the demands of astronomical
observing. As much as possible, system complexity is minimized by
the use of a "Menu Driven" user interface that, in most
cases, requires only single keystrokes to make the telescope
perform complex tasks. And all PC-TCS-controlled OGS telescope systems
will script with the integration of this ASCOM compliant operating
system. |
