This project uses a Feather M4 and Trinamic's TMC-2226 stepper motor driver to enable you to take long exposures of the night sky with just about any camera. This project was designed to be a more economical project vs. commercial equatorial mount trackers. And it can easily (and cheaply) be modified and customized, a feature many other trackers lack.

This project assumes that you know how to use hand and power tools. It also assumes some experience with breadboarding and electronics. Expect this project to take you 3-6 hours to assemble and just as many, if not more, to test.
