Best star trackers for astrophotography

The best star trackers for astrophotography have changed the scene forever by counteracting the rotation of our planet. Until only a few years ago a long exposure of over about 10 seconds caused stars to blur. That made it very difficult to extract much data from deep-sky objects such as nebulae, but also from the Milky Way. Cue the invention of the star-tracker, which is basically a shrunken equatorial mount, but designed for cameras instead of telescopes.

Like an equatorial mount, a star tracker needs to be aligned (often with the help of a smartphone app) with the north celestial pole (the star Polaris) in the northern hemisphere or the south celestial pole in the southern hemisphere. It then keeps your camera in sync with Earth’s rotation. That way it counteracts the rotation of the Earth and keeps the target object still in a composition, thus allowing blur-free long exposures.
