When taking pictures of the stars you will get star trails if you don't compensate for the earth's movement. In some cases this may be a desired shot! It can be a pretty cool picture. But for deep sky imaging it's not desired.
I am just getting into astrophotography. I know it can be expensive to buy gear and I don't know, well, anything yet. To get started and start learning I made a couple prototype isosoles barn door trackers, one mechanical and one motorized like this, to prove it works. Then I decided to get more precise and 3D print things.
All docs are in docs/ and there is an Index. My goal is to write up everything you need in order to print, assemble, and use this tracker. Hope you find some value in this!
Clear Skies!
