TelescopeSlewToAltAz Method

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

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

Syntax

C++

Copy

public void SlewToAltAz(
	double Azimuth,
	double Altitude
)

Public Sub SlewToAltAz ( 
	Azimuth As Double,
	Altitude As Double
)

public:
virtual void SlewToAltAz(
	double Azimuth, 
	double Altitude
) sealed

Parameters

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

Implements

ITelescopeV3SlewToAltAz(Double, Double)

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. The device did not successfully complete the request.

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.
