I run INDI from my Pi with an EQStar controller from Astrogadget on a Losmandy G11S, mount type is Synscan/EQMOD. When using the default guider algorithm I don't see a calibration button anywhere. I have the Smart option selected. When I click Guide, it seems to work nevertheless. What am I missing, is calibration not required? Or did I not look in the right place?
There is no specific calibration button because the first time that guiding is started, calibration is automatically done. If you clear the guiding calibration after that (this can be done manually or automatically when the mount moves) again the calibration will be done automatically before guiding is started. Otherwise the calibration will be reused.
