void SlewToTargetAsync()


This Method must be implemented if CanSlewAsync returns True. Raises an error if starting the slew failed. Returns immediately after starting the slew. The client may monitor the progress of the slew by reading the RightAscension, Declination, and Slewing properties during the slew. When the slew completes, Slewing becomes False. The slew may fail to start if the target coordinates are beyond limits imposed within the driver component. Such limits include mechanical constraints imposed by the mount or attached instruments, building or dome enclosure restrictions, etc. Raises an error if AtPark is True, or if Tracking is False.


MethodNotImplementedExceptionIf the method is not implemented and CanSlewAsync is False
