Telescope.TrackingRate Property

Telescope.TrackingRate (read-write, DriveRates)

The current tracking rate of the telescope's sidereal drive

Syntax

Telescope.TrackingRate [= DriveRates]

The property syntax has these parts:

Part	Description
Value (DriveRates)	The current tracking rate of the telescope's sidereal drive

Remarks

Supported rates (one of the DriveRates values) are contained within the TrackingRates collection. Values assigned to TrackingRate must be one of these supported rates. If an unsupported value is assigned to this property, it will raise an error.

The currently selected tracking rate be further adjusted via the RightAscensionRate and DeclinationRate properties. These rate offsets are applied to the currently selected TrackingRate.

Mounts must start up with a known or default tracking rate, and this property must return that known/default tracking rate until changed. If the mount's current tracking rate cannot be determined (for example, it is a write-only property of the mount's protocol), it is permitted for the driver to force and report a default rate on connect. In this case, the preferred default is Sidereal rate.

Symbolic Constants

The (symbolic) values for DriveRates are:

Constant	Value	Description
driveSidereal	0	Sidereal rate
driveLunar	1	Lunar rate
driveSolar	2	Solar rate
driveKing	3	King rate
