Can I use a standard Ethernet cable for my Starlight HSM motor?
No. Standard Ethernet/network cables (RJ45) have a different internal wiring configuration (pinout). Using one will not work and could potentially damage your motor or controller. This Stepper Motor Cable has the specific custom pinout required by Starlight HSM and compatible motors.
Is the 1m length of this HSM motor cable long enough for most setups?
A 1m (3.3 ft) length is generally sufficient for connecting a focuser motor to a controller mounted on the telescope's dovetail or optical tube. For more complex setups where the controller is mounted further away, you may need to plan your cable management accordingly or seek a longer, correctly-wired extension.
Will this cable connect my Optec QuickSync motor to a Pegasus Astro Pocket Powerbox?
Yes, this cable is designed to connect compatible motors, including the Optec QuickSync FT, to the stepper motor port on Pegasus Astro controllers like the Pocket Powerbox series or the Ultimate Powerbox.
How do I confirm this is the right cable for my Starlight POSI Drive motor?
This cable is listed as fully compatible with the Starlight POSI Drive Motor system. It uses the same custom-wired RJ45 connection as the HSM motors, making it the correct choice for connecting it to your Pegasus Astro controller.
I have a Starlight HSM 35 on my Explore Scientific ED127. Is this the cable I need?
Yes. If you are using any Starlight HSM series motor, including the HSM 35, with a controller that has an RJ45 stepper output, this 1m cable is the correct accessory to ensure proper power and data transmission for autofocusing.
Does this HSM motor cable support temperature compensation focusing?
The cable itself simply transmits power and motor commands. Temperature compensation is a function of your controller (like a Pegasus Powerbox), its temperature sensor, and your autofocus software (N.I.N.A., SGP, etc.). This cable reliably executes the focus motor movements required by those systems.
