Telescope.SiderealTime Property

Telescope.SiderealTime (read-only, Double)

The local apparent sidereal time from the telescope's internal clock (hours, sidereal)

Syntax

Telescope.SiderealTime

The property syntax has these parts:

Part	Description
Value (Double)	The local apparent sidereal time from the telescope's internal clock (hours, sidereal)

Remarks

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.
