ITelescopeV3SlewToAltAzAsync Method

This Method must be implemented if CanSlewAltAzAsync returns True.

Namespace:  ASCOM.DeviceInterface
Assembly:  ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 3c9121baba46811fe6e53a58a05935662261416d
void SlewToAltAzAsync(
	double Azimuth,
	double Altitude


Type: SystemDouble
Azimuth to which to move
Type: SystemDouble
Altitude to which to move to
MethodNotImplementedExceptionIf the method is not implemented and CanSlewAltAzAsync is False
InvalidValueExceptionIf an invalid azimuth or elevation is given.
This method should only be implemented if the properties Altitude, Azimuth, RightAscension, Declination and Slewing can be read while the scope is slewing. Raises an error if starting the slew fails. Returns immediately after starting the slew. The client may monitor the progress of the slew by reading the Azimuth, Altitude, and Slewing properties during the slew. When the slew completes, Slewing becomes False. The slew may fail 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. The TargetRightAscension and TargetDeclination properties are not changed by this method.

Raises an error if AtPark is True, or if Tracking is True.

This is only available for telescope InterfaceVersions 2 and 3
