Pegasus Astro Stepper Motor Cable for Lacerta Motor

Product Overview

This is the Pegasus Astro stepper motor cable wired for Lacerta focus motors. It connects a Lacerta motor to a Pegasus Astro focus controller, matching the pin arrangement the Lacerta motor expects to the connector on the Pegasus end.

Pegasus focus controllers ship with a cable for their own motors. If you are driving a third-party motor instead, the wiring order differs, and this cable is the Lacerta-specific version.

Who It's For

This is a good match if you:

• Own a Lacerta focus motor and want to run it from a Pegasus Astro focus controller rather than replacing the motor.
• Are migrating to Pegasus control and want to keep the motor already fitted to your telescope.
• Need a spare for an existing Lacerta-to-Pegasus setup.

Key Features & Design

• Lacerta-specific pinout: wired for the coil order a Lacerta stepper expects, so the motor turns correctly rather than stalling or running backwards.
• Direct replacement for adapting: no splicing, no adapter stack — one cable end to end.
• Works with the Pegasus focus controller range that uses the standard Pegasus motor connector.

Recommended Uses

• Driving an existing Lacerta focus motor from a Pegasus Astro focus controller.
• Keeping a working third-party motor when upgrading the controller.
• Carrying a spare motor cable in an observatory or travel kit.

Compatibility and Accessory Notes

• Motor side: wired for Lacerta focus motors specifically.
• Controller side: Pegasus Astro focus controllers using the standard Pegasus stepper motor connector.
• Not interchangeable with other third-party cables. The MSM/Rigel and Starlight HSM cables use different wiring and are sold separately.
• Cable only. The motor and the controller are separate purchases.

Good to Know Before You Order

• Pinout is motor-specific. A stepper cable is not generic — using the wrong one can leave the motor unresponsive or turning the wrong way. If you are unsure which motor you have, send us the model and we will confirm the right cable before you order.
• This is a cable, not a motor kit. It adapts a motor you already own to a controller you already own.
• Check your controller connector. If your Pegasus controller uses an RJ45 or DB9 motor port, the matching cable for that port is a different part.

Frequently Asked Questions

Is it difficult to set up?

No. It is a single cable — motor at one end, controller at the other. There is nothing to wire and nothing to configure.

Why can't I use the cable that came with my Pegasus controller?

That cable is wired for Pegasus motors. A Lacerta motor uses a different coil order, so it needs a cable wired to match.

Will it work with an MSM or Rigel motor?

No. Those use the MSM/Rigel cable, which is a separate part.

What happens if I use the wrong cable?

Typically the motor will not move, will move erratically, or will run in reverse. Fitting the correct cable resolves it.

Bottom Line

In short: the Lacerta-to-Pegasus stepper cable that lets a Pegasus focus controller drive a Lacerta motor. Confirm your motor model and it is a straight plug-in.
