TelescopeChoose Method
The Choose() method returns the DriverID of the selected driver. Choose() allows you to optionally pass the DriverID of a "current" driver (you probably save this in the registry), and the corresponding telescope type is pre-selected in the Chooser's list. In this case, the OK button starts out enabled (lit-up); the assumption is that the pre-selected driver has already been configured.
