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 int...

SV905C Astronomy guiding camera has USB 2.0 interface output; ST4 guide star interface; can compatible with PHD2; MDL; NINA; SKY-X and other software guide star, easily for focusing and
Compatibility Compatibility low the original OnStep design standards. The hand controller by default is designed to communicate onboard ST4 port. The requirements:
So, the ST-4 became the defacto standard for autoguiders, an it had a very specific set of instructions for use on mounts. Over the years, as other companies developed newer, faster small
Industry standard RJ12 jack ST4 interface with optional 5V power on pin 1. This supports the BHC and SHC but it is up to you to verify the compatibility of any other device attached (camera
SV905C Astronomy guiding camera has USB 2.0 interface output; ST4 guide star interface; can compatible with PHD2; MDL; NINA; SKY-X and other software
Unfortunately, there is no standardized interface that all manufacturers (or even within a single manufacturer) use for this function. However, most mounts do use a de-facto standard that for lack of
I think of it as a USB to ST-4 converter, conveniently included as part of the guide camera with its existing USB interface. The camera itself doesn''t contribute to auto-guiding beyond feeding
Building your own ST-4 adapter costs less than available commercial solutions (~6 USD) and on the top of providing autoguiding, the custom driver also has a working GOTO functionality.
''s Arduino ST4 interface lets you connect your PC to a reasonably priced motorized telescope mount, without ripping it apart. The ST4 port is a very basic interface.
Basically, you need to build the USB-ST4 interface described in the github project page and modify your control pad like explained here if it doesn''t have an ST4 port.
