Rigel Stepper Motor Temperature Sensor
Maintain peak performance during long or intensive focusing sessions with Rigel Systems' external temperature sensor—designed specifically for their stepper focus motor controllers (such as the nSTEP, usb-nSTEP, and wifi-nSTEP). As telescope tubes contract or expand with temperature changes, focus drift is a common challenge in astrophotography. This sensor delivers accurate ambient readings unaffected by internal heat sources, enabling auto-focus systems to adjust continuously and precisely. Ideal for serious imagers seeking steady sharpness throughout the night.
