Last night I wanted to play with tracking rates, especially the custom ones. I can select 'Custom' in the INDI manager, but when I then try to change the values it will only accept a very narrow range (15.035-15.051) around the nominal sidereal value. Larger or smaller values make the button red, and the value is not accepted.
Is that an input limit in the manager, or coming from the mount? Is there a way around?
