Description

17668 - TCF-Si Integrated Temperature Compensating Focuser, 2-inch motorized focuser.  Fully compatible with the original robotic TCF-S Temperature Compensating Focuser, the TCF-Si features an integrated control circuit with RJ12 socket for connection to any control computer.  

An 18-inch temperature probe can be attached directly to the telescope OTA to measure to current temperature and the integrated control circuit will compensate for the changing telescope focus.  Optec's USB/Serial cable makes the connection to any control computer while the TCF-S Commander software and ASCOM driver allows any higher level ASCOM software client to provide auto-focus.
