Build your own tracking and GoTo mount for DSLR astrophotography

Arduino TeamDecember 18th, 2019

Astrophotography can be challenging, in a large part because your subject matter — or your base, the Earth rather — is constantly moving. In order to take excellent long exposures of far-off objects, Redditor intercipere came up with a beautiful 3D-printable, star-following mount that holds and rotates a DSLR camera.

Now intercipere can simply input the RA/DEC coordinates and the device will automatically move to a desired target in the sky.

Motion is handled by an Arduino Uno and two small stepper motors, with a 16×2 LCD shield user interface. The rig is capable of tracking for at least four minutes, producing this photo of the Andromeda galaxy with a cheapo lens from a heavy light polluted area.
