Instructables user DentDentArthurDent builds and integrates an Arduino-powered star-finder with a small reflecting telescope, to easily find the galaxies, nebulae and clusters that he wanted to observe.
He states:
Traditional methods of finding objects in the night sky (using charts, maps, following constellations) are slow and require experience, and motorised ‘Go-To’ telescopes are very expensive. This project finds a happy medium between the two. Clear night skies are not common, so using this Arduino star-finder allows you to make the most of your precious viewing time.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
