Add Temperature Compensation to Focusing:
Telescopes change focus as temperature changes expand/contract the length of the telescope tube as temperature increases/decreases. Adding the external temperature sensor to the usb-nSTEP allows your autofocus software to and automatically compensate for these temperature changes. Unlike internal temperature sensors located inside the controller that are affected by the heat generated by the electronics, the external temperature sensor can be attached to the telescope to get a more accurate measurement of the ambient temperature.
