Detailed Description


Data Structure Documentation

◆ TelescopeControl

class TelescopeControl

"Controlling a telescope" means receiving position information from the telescope and sending GOTO commands to the telescope. No esoteric features like motor focus, electric heating and such. The actual controlling of a telescope is left to the implementation of the abstract base class TelescopeClient.

Main class of the Telescope Control plug-in.
