Return Value

The smallest increment in exposure time supported by StartExposure.

Implements

ICameraV2..::..ExposureResolution

Remarks

This can be used, for example, to specify the resolution of a user interface "spin control" used to dial in the exposure time.

Please note that the Duration provided to StartExposure does not have to be an exact multiple of this number; the driver should choose the closest available value. Also in some cases the resolution may not be constant over the full range of exposure times; in this case the smallest increment would be appropriate.

It is recommended that this function be called only after a connection is established with the camera hardware, to ensure that the driver is aware of the capabilities of the specific camera model.

This is only available for the Camera Interface Version 2

Exceptions

ExceptionCondition
ASCOM..::..NotConnectedExceptionMust throw an exception if the information is not available. (Some drivers may require an active connection in order to retrieve necessary information from the camera.)
ASCOM..::..InvalidValueExceptionMust throw an exception if not valid.
