Move the telescope to the given equatorial coordinates, return immediately after starting the slew.

Namespace: ASCOM.DeviceInterface
Assembly: ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 6.0.0.0 (6.1.1.2619)

Syntax

C#
void SlewToCoordinatesAsync(
	double RightAscension,
	double Declination
)
Visual Basic
Sub SlewToCoordinatesAsync ( _
	RightAscension As Double, _
	Declination As Double _
)
Visual C++
void SlewToCoordinatesAsync(
	double RightAscension, 
	double Declination
)

Parameters

RightAscension
Type: System..::..Double
The destination right ascension (hours). Copied to TargetRightAscension.
Declination
Type: System..::..Double
The destination declination (degrees, positive North). Copied to TargetDeclination.

Remarks

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.

The target coordinates are copied to TargetRightAscension and TargetDeclination whether or not the slew succeeds. Raises an error if AtPark is True, or if Tracking is False.

Exceptions

ExceptionCondition
MethodNotImplementedExceptionIf the method is not implemented and CanSlewAsync is False
InvalidValueExceptionIf an invalid right ascension or declination is given.
