The name, position and type of the current chosen object are displayed on a small LCD screen on the handset. Using this, and known coordinates for a list of objects (my initial code includes 45 astronomical objects, and it's easy to expand this list if you choose), their current position in the night sky (relative to the observer) is calculated. How: The Arduino receives position and time data from a small GPS module. Clear night skies are not common, so using this Arduino star-finder allows you to make the most of your precious viewing time. This project finds a happy medium between the two. Why: 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.

The electronics are all contained within a convenient handset, attached to the telescope mount on a 0.5m cable. It then measures the current heading and elevation of the telescope, and displays to the user how to orientate their telescope so that the chosen target object will be visible.

What: This device calculates the current position in the night sky of a list of galaxies, nebulae and star clusters. In this project I made and integrated an Arduino-powered star-finder with a small reflecting telescope, to allow me to easily find the galaxies, nebulae and clusters that I wanted to observe. Owning a small telescope can give a lot of pleasure, but it's often a struggle trying to locate specific objects in the night sky.
