ITelescopeV3SlewToAltAz Method

Move the telescope to the given local horizontal coordinates, return when slew is complete

Namespace: ASCOM.DeviceInterface
Assembly: ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 6.0.0.0 (6.6.9999.9999)

Syntax

C++

Copy

void SlewToAltAz(
	double Azimuth,
	double Altitude
)

Sub SlewToAltAz ( 
	Azimuth As Double,
	Altitude As Double
)

void SlewToAltAz(
	double Azimuth, 
	double Altitude
)

Parameters

Azimuth Double: Target azimuth (degrees, North-referenced, positive East/clockwise).
Altitude Double: Target altitude (degrees, positive up)

Exceptions

Exception	Condition
MethodNotImplementedException	If the method is not implemented and CanSlewAltAz is False
InvalidValueException	If an invalid azimuth or elevation is given.
ParkedException	If the telescope is parked
NotConnectedException	If the device is not connected
DriverException	An error occurred that is not described by one of the more specific ASCOM exceptions. Include sufficient detail in the message text to enable the issue to be accurately diagnosed by someone other than yourself.

Remarks

This Method must be implemented if CanSlewAltAz returns True. Raises an error if the slew fails. 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 later.
