from what I understand, worm gears work really well and because of the
reduction, the motor needs to sping at a decent rpm, it doesn't have
tospin that slow. I am using steppers, because it is easy to count the
steps and then calibrate because of how much you're drifting.While with
a regular DC motor you could only do something like that in a
Monte-Carlo/binary kinda way. also, adjusting DC motors is not
necessarilly linear and since adjusting a stepper is "discrete" it
would be way easier.

You need to move at 1/2 the resolution otherwise you can see the steps. So
let's say each step would be 1/4 arc-second
I was going with one step per thingy, and then assuming microstepping
to get sub-thingy :-)
I will just mention: https://www.hpcgears.com/pdf_c33/22.0.pdf as an option.
