Starlight Xpress Adapive Optics Guiding System without OAG. This version comes without off-axis guider so it can be use with any CCD camera that already has an OAG, such as the QSI ccd cameras and many others.
The SX-AO-USB is an updated and improved version of the AOLF unit that was launched in 2008. It adds an internal USB to serial converter, so that a direct USB connection may be used, and the stepper motor drivers have increased torque capability to ensure optimum performance under all conditions.
