Here is my full setup including an ST-80 f5 guide scope with an SBIG ST-4 autoguider which I have just purchased second-hand. The ST-80 is on loan (ta Pete!).
The ST-4 is regarded as a 'classic' piece of equipment and is still used to guide some
of the worlds biggest telescopes.
It uses relays to control the switches on the telescope drive, and
so is compatible with a lot of different equipment.
The ST-4 is no longer made (The more expensive STV has taken over).
On the table is my laptop, eyepiece box and ST-4 control box.
I have MaximDL software on the laptop that can interface with the ST-4 - that give me more control over the ST-4. The
laptop also gets used for capturing webcam images and focussing my Canon 300D with software called DSLRFocus (highly recommended).
