My first couple usages of the tracker went pretty well, but it was a nightmare to setup the polar alignment. There was a lot of wiggle where the tripod mount screwed to the tracker. I didn’t feel safe with the amount of wiggle, and every time I adjusted the camera it would mess up the alignment.
Most of the wobble seemed to be where the T-Nut was set into the plywood. The T-Nut sticks out too much so the tripod mount isn’t flush.
Now the mount is much more stable
I also added a small finder scope to the tracker. You can set the alignment of the scope by putting a straw on the hinge and aiming it at something relatively far away in the house. Then you can adjust the finder scope to calibrate it.
I took some test shots but I apparently messed up the focus after I initially set it up. All the stars looks like big orbs instead of points.
The alignment was much easier though, and I noticed even less movement from shot to shot over 30s exposures and I couldn’t see any trails.
