FocusLynx Temperature Probe Kit

#19539 - Optional External Temperature Probe Kit

FocusLynx Temperature Probe KitThough the QuickSync motors include an on-board temperature probe for measuring ambient temperature changes, many purists prefer the measurement be made directly at the telescope OTA.  To satisfy this requirement the #19539 External Temperature Probe Kit is available. 

For users of the original Microtouch motors which do not include an on-board temperature, the #19539 External Temperature Probe Kit can provide the sensor for Temperature Compensation (TC) which would not otherwise be available.
