TelescopeGuideRateRightAscension Property |
The current Right Ascension movement rate offset for telescope guiding (degrees/sec)
Namespace: ASCOM.DriverAccess
Assembly: ASCOM.DriverAccess (in ASCOM.DriverAccess.dll) Version: 3351c4f3fa64146a7efd5b51ed4591e32a0a5484
SyntaxExceptions| Exception | Condition |
|---|---|
| PropertyNotImplementedException | If the property is not implemented |
| InvalidValueException | If an invalid guide rate is set. |
| NotConnectedException | If the device is not connected |
| DriverException | An error occurred that is not described by one of the more specific ASCOM exceptions. The device did not successfully complete the request. |
Remarks
This is the rate for both hardware/relay guiding and the PulseGuide() method.
This is only available for telescope InterfaceVersions 2 and later.
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.
