kinda -
You could of course write some algorithm to change the speed of the
motor to correct for the change in angular velocity.
I actually have no clue myself,
but it seems to me if the tracker has an angular velocity
of 15 degrees per hour (or 1 degree every 4 minutes)
and one uses a wide angle like 24mm or so,
you might not need tracking correction for exposures of a few minutes....
Would there be a noticeable difference in tracking between a
straight and bent rod?
Anybody out there know more about this?
The need for correction would go up with the focal length,
and length of exposure - but at what point does it become critical?
