Pegasus Astro Saddle Powerbox Puck for Avalon M-UNO and LINEAR

Product Overview

This is the Pegasus Astro Saddle Powerbox puck for the Avalon M-UNO and LINEAR mounts. The Saddle Powerbox bolts straight onto an NYX-101 with no extra hardware; on every other mount it needs a puck cut for that mount's saddle interface, and this one covers both Avalon models.

It is a mechanical adapter. It carries the Saddle Powerbox — it does not add or change anything electrical.

Who It's For

This is a good match if you:

• Own a Saddle Powerbox and an Avalon M-UNO or LINEAR and need the part that joins the two.
• Run a fast-slewing belt-driven Avalon and want the cable bundle to start at the saddle rather than tracking the full range of motion from the base.
• Are moving a Saddle Powerbox between mounts and want a puck left permanently on each one.

Key Features & Design

• Fits two mounts: one puck covers both the Avalon M-UNO and the LINEAR.
• Puts the powerbox at the saddle: the Saddle Powerbox sits between the mount and the telescope, so power, dew and USB all originate above the moving axes.
• Part of a mount-specific range: Pegasus Astro publishes pucks for the AM5/AM3, NEQ6 and EQ6-R, RST-135 and RST-300, HEQ5, AZ-EQ6, iOptron CEM26 and GEM28, and Star Adventurer GTi.
• Mechanical only: no electronics, no ports, no effect on the Saddle Powerbox's outputs or sensors.

Recommended Uses

• Fitting a Saddle Powerbox to an Avalon M-UNO or LINEAR for on-mount power and USB distribution.
• Shortening cable runs on a single-arm mount where routing across the axes is the awkward part.
• Keeping a dedicated puck on each mount in a multi-mount setup so the powerbox itself can move between them.

Compatibility and Accessory Notes

• Requires a Saddle Powerbox. The puck is the interface between that unit and your mount; on its own it does nothing.
• Fits the Avalon M-UNO and LINEAR. Other Avalon models are not named in Pegasus Astro's published fitment for this part.
• Not needed on an NYX-101. The Saddle Powerbox attaches to that mount directly.
• The Saddle Powerbox itself is 110 x 110 x 32 mm, takes 12–14 V DC, and provides four 12 V outputs (10 A total), two PWM dew channels, two USB 3.1 and two USB 2 ports, and onboard temperature, humidity and dew-point sensing. Its clamp accepts Losmandy and Vixen bars and is rated to a 40 kg payload.
• On a different Avalon? Tell us the model and we will check the puck range against it before you order.

Good to Know Before You Order

• The puck is mount-specific. This one covers the M-UNO and LINEAR; the HEQ5, AZ-EQ6, NEQ6/EQ6-R, CEM26/GEM28, GTi and AM5 versions are separate parts, all of which we stock.
• Pegasus Astro publishes no material, dimensions or weight for the pucks. Those specification rows are left out rather than filled with figures we cannot source from the manufacturer.
• It is an adapter, not a powerbox. Ordering this alone gets you the mounting interface; the Saddle Powerbox is a separate product.
• The powerbox adds weight above the saddle, which is worth counting into your payload alongside the telescope and camera.

Frequently Asked Questions

Is it difficult to set up?

No. The puck fixes to the mount, and the Saddle Powerbox then attaches to the puck. It is a bolt-on part with no wiring and no configuration.

Does one puck cover both the M-UNO and the LINEAR?

Yes — Pegasus Astro publishes it as a single part for both mounts.

Do I need this if I have an NYX-101?

No. The Saddle Powerbox mounts to the NYX-101 without any additional component.

Does it change what the Saddle Powerbox can do?

No. Outputs, dew channels, USB ports and sensors are all unaffected — the puck only carries the unit.

Can I leave the puck on the mount permanently?

Yes, and that is the usual approach when the powerbox moves between mounts.

Bottom Line

In short: the mount-specific adapter that puts a Pegasus Astro Saddle Powerbox onto an Avalon M-UNO or LINEAR. One bolt-on part covering both mounts, and the cable bundle starts above the axes instead of crossing them.
