Reading the property will raise an error if the value is unavailable. If the telescope is not capable of asynchronous slewing, this property will always be False. The definition of "slewing" excludes motion caused by sidereal tracking, PulseGuide, RightAscensionRate, and DeclinationRate. It reflects only motion caused by one of the Slew commands, flipping caused by changing the SideOfPier property, or MoveAxis(TelescopeAxes, Double).


ASCOM..::..PropertyNotImplementedExceptionIf the property is not implemented.
