Player One ST4 Autoguider Cable - 2M

Overview

The Player One ST4 Autoguider Cable is a 2-metre guiding lead fitted with a 6-pin crystal-head (RJ-style) connector at each end. It carries autoguider correction signals between the ST4 guide port on a guide camera or standalone autoguider and the ST4 guide input on an equatorial mount. The cable is made from high-quality flexible flat wire, so it stays supple in the cold and routes cleanly along an imaging train.

Who It's For

This is a good match if you guide your mount over the ST4 (pulse-guide) interface and need a replacement or spare lead. It suits deep-sky astrophotographers running a separate guide camera and anyone whose mount accepts ST4 corrections directly.

Key Features & Design

• 2-metre length: reaches from a guide camera on the scope to the mount's ST4 port with slack for cable management.
• 6-pin crystal-head connectors: the standard ST4 interface on both ends.
• Flexible flat-wire construction: stays pliable at low temperatures and lies flat against the tube.

Recommended Uses

Pulse-guiding an equatorial mount from a guide camera or autoguider during long-exposure deep-sky imaging, and as a spare lead in a travel or observatory kit.

Compatibility & Accessory Notes

The cable uses the 6-pin ST4 (RJ-style) standard found on most guide cameras and mount ST4/autoguide ports. It carries guide-correction signals only — it is not a USB data cable and does not power the camera. If you are unsure whether your camera and mount both use the ST4 6-pin interface, send us the two models and we will confirm the fit.

Good to Know Before You Order

• Signal cable, not data or power: it passes ST4 guide pulses between camera and mount, and does not carry image data or supply power.
• ST4 interface required at both ends: your guide camera and mount each need a 6-pin ST4 port to use it.
• Fixed 2-metre length: this listing is the 2-metre lead, with no other length option.

Frequently Asked Questions

Is it difficult to set up?

No — it plugs into the ST4 port on the guide camera at one end and the mount's ST4 input at the other, and clicks into place like a standard RJ connector.

What is it best used for?

Carrying autoguider corrections from a guide camera to an equatorial mount during long-exposure astrophotography.

Does it carry image data or power?

No — it is an ST4 signal lead only. Image download and camera power run over the camera's separate USB connection.

Will it fit my camera and mount?

If both use the 6-pin ST4 guide interface, yes. Send us your camera and mount models and we will check before you order.

Bottom Line

In short: a 2-metre ST4 guide lead with 6-pin crystal-head connectors on both ends, made from flexible flat wire, for pulse-guiding an equatorial mount from a guide camera.
