ST4 Interface Standard
ST-4 is an interface you will come across using astronomy equipment with some form of computer control. It might be as an ST-4 socket on a mount, a socket on the back of an astronomy camera, or an interface on some other form of guiding device such as an AstroHutech Hinode Solar Guider. The purpose of this project is to connect a telescope to a computer through the mount guide port (ST-4 port) using an arduino in order to cheaply add GOTO and autoguiding capabilities. The ST-4 Port is present on some computerized mounts and it is easy to add one to motorized mounts like the EQ3 / EQ4 / EQ5.
