Rigel systems nstep setup


#1

I placed a Rigel systems nstep stepper motor on my orion astrograph. Does anybody know a good step size for this setup?

This will depend on a lot of factors specific to your gear: focal length, gear ratios your Rigel uses, etc. Your best bet is to just start with a value around 100 and 9 steps and run the autofocus routine then note the max and min values of the V curve. The usual suggestion is adjust the step size until the max value (with 9 or whatever total steps you choose) to be between 2x and 3x the minimum value.
I have 3 Rigel focusers, 1 for each of the 3 scopes mounted on my mount. The step sizes for these range from 30 to 100.

read the manual. It’s well documented.
