Hi,
is this on a specific mount or is it common for most mounts?
I'd imagine the rate to be different as gear ratios would be different amongst mounts, So whilst a small change in speed may be sufficient for one, another might need a larger change due to a higher gear ratio.

I was using 0.5x sidereal as the change increment but will try 1x. My gear ratio is around 1178:1 with 1/32 microstepping.
to achieve sidereal rate, my step freq is 87 steps/sec.

So I'd have to change that to 174steps/sec for an East Pulse or 0 for a West Pulse?
