PropertyNotImplementedException | When the Offset property is not implemented or is operating in OFFSET VALUE mode. |

This is an optional property and can throw a PropertyNotImplementedException.
When Offset is operating in OFFSETS INDEX mode:The returned offset names are at the manufacturer / driver author's discretion and could for example be: "Low gain", "Medium gain" and "High gain"to match the offset to different camera use scenarios. Typically the application software will display the returned offset names in a drop list, from which the astronomer can select the required value. The application can then configure the required offset by setting the camera's Offset property to the array index of the selected description.
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 in Camera Interface Version 3 and later.
