I am attempting to control the scope with the IOS or the Mac SkySafari6 Pro. I can connect and I can manual slew the scope using on screen arrows. However, whenI attempt to GoTo a target it get the following warnings "Command Failure : The scope can't slew to the target coordinates because they are out of reach of the mount". These are not wild GoTo. Polaris to Alderamin. It seems there is a slew limit setting I cannot adjust? Any assistance would be greatly appreciated.
