Star Tracker

thingiverse

This helper tool makes it easier to take nighttime pictures with a star tracker, but buying extra hardware adds to its cost. I personally use a device called NanoTracker. To get started, edit this model according to your location at https://www.tinkercad.com/things/iOduLsiFtEH. First, position the star tracker at a right angle towards north. You can place a compass on this base plate for reference. The correct angle will depend on your location's latitude; Google it and adjust the tracker accordingly.
