Exceptions

Exception	Condition
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

Must be implemented, must not throw a PropertyNotImplementedException.

It is required for a driver to calculate this from the system clock if the telescope has no accessible source of sidereal time. Local Apparent Sidereal Time is the sidereal time used for pointing telescopes, and thus must be calculated from the Greenwich Mean Sidereal time, longitude, nutation in longitude and true ecliptic obliquity.
