public interface FocusAccessible

A generic interface describing the essential functionality a telescope must provide to work as an astronomical telescope. Further subclasses may be specified for increased performance. Note that very simple telescope might even only provide a subset of these commands, this interface is a compromise between what you expect on a telescope and what is essentially necessary.
