Re: Arc seconds per step for high end mounts.

I would say that if the camera resolution is 1", then you should move the dot one step left when defining the tracking resolution, ca. 0.1" /step. If you use steppers it is that step and if you use servo, it is the reslution of the encoder. I had earlier a home made mount with steppers and I noticed that 4 steps/ arc sec was to coarse and caused vibrations. In that case the the max slewing speed OK, it was 144x trackig speed but I had to drop that to get better tracking resolution.
