public double SiderealTime { get; }

Property Value

Type: Double


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.
