This thesis puts forward the design for a device called STARS (Scope Temperature Auto-Regulation System), which is an advanced yet affordable solution to the problem of moisture condensation on small telescope lenses. A design is achieved which can precisely control the temperature of a resistive heating band by driving power transistors with a pulse-width modulated signal generated by a Raspberry Pi Pico microcontroller. The device is capable of switching between user-operated and automatic control modes and integrates multiple temperature and humidity sensors to provide a smart solution to a problem that is almost exclusively addressed by the current market using purely analog devices which feature poor feedback and user control.
