After a night out testing how the tracker performed, i managed to get a few samples that are usable (sort of a windy night). I took a 159s (photo with random stars), 140s (single landscape shot of milky-way) and a few 30s exposures (merged 4 of them to get the detailed vertical shot of the milky-way).

with the longer exposures i got some camera vibration either due from the motor or from the wind, or maybe both, or because i just learned that with longer than 30s exposures my camera will take 2 photos back-to-back to help with hot pixels. I will go out again soon and see if i can narrow down what happened! The good thing was 70% of my 30s exposures turned out pin-point with no trails, even the long exposures shot to have no visible trails which means tho tracker worked!
