ITelescopeV3GuideRateRightAscension Property
The current Right Ascension movement rate offset for telescope guiding (degrees/sec)

Namespace: ASCOM.DeviceInterface
Assembly: ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 6.0.0.0 (6.2.0.2774)
Syntax
double GuideRateRightAscension { get; set; }

Property Value

Type: Double
Exceptions
ExceptionCondition
PropertyNotImplementedExceptionIf the property is not implemented
InvalidValueExceptionIf an invalid guide rate is set.
Remarks
This is the rate for both hardware/relay guiding and the PulseGuide() method.

This is only available for telescope InterfaceVersions 2 and 3

NOTES:

  • To discover whether this feature is supported, test the CanSetGuideRates property.
  • The supported range of this property is telescope specific, however, if this feature is supported, it can be expected that the range is sufficient to allow correction of guiding errors caused by moderate misalignment and periodic error.
  • If a telescope does not support separate guiding rates in Right Ascension and Declination, then it is permissible for GuideRateRightAscension and GuideRateDeclination to be tied together. In this case, changing one of the two properties will cause a change in the other.
  • Mounts must start up with a known or default right ascension guide rate, and this property must return that known/default guide rate until changed.
