From the developer:
POTH is an incredibly useful tool for both testing and routine observing. It started out as a "plain old telescope handset" (hence the acronym), but it has grown a lot since then.
POTH has many useful features such as traffic logging and its own set of "handset" controls for the telescope, dome, and focuser. There is a detailed help file for POTH, accessible from the Start menu, ASCOM Platform, Scope/Dome hubs.
