Why and How to Use a Star Tracker for Photos of the Night Sky
Astrophotography is generally a race against time to capture as much subtle starlight we can before the stars create trails in our images.

Fortunately, a tool exists to circumvent this barrier to reveal more of the hidden magic we have in our night sky.
