DomeAzimuth Property |
Exception | Condition |
---|---|
PropertyNotImplementedException | If the property is not implemented |
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. |
The specified azimuth is the position on the sky that the observer wishes to observe. It is up to the driver to determine how best to locate the dome in order to expose that part of the sky to the telescope. This means that the mechanical position to which the Dome moves may not correspond exactly to requested observing azimuth because the driver must coordinate multiple shutters, clamshell segments or roof mechanisms to provide the required aperture on the sky.
Raises an error only if no azimuth control. If actual dome azimuth can not be read, then reports back the azimuth of the last slew position.
The supplied azimuth value is the final azimuth for the dome, not the telescope azimuth. ASCOM Dome drivers do not perform slaving calculations i.e. they do not take account of mount geometry and simply move where they are instructed. Any such slaving calculations must be done by the application.
