PHD2 Guiding

A free, open-source autoguiding application — the name stands for 'Push Here Dummy' — that images a guide star and issues corrections to the mount to hold a target steady through long exposures. PHD2 is the de-facto standard guider, used on its own or driven by imaging suites like N.I.N.A. and Ekos.
