Pegasus Astro Saddle Powerbox Puck for Sky-Watcher Star Adventurer GTi

Product Overview

This is the Pegasus Astro Saddle Powerbox puck for the Sky-Watcher Star Adventurer GTi. 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 is the GTi one.

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 a Star Adventurer GTi and need the part that joins the two.
• Travel with the GTi and want power, dew and USB consolidated onto the mount head so there is one lead to the ground instead of five.
• Are moving a Saddle Powerbox between mounts and want a puck left permanently on each one.

Key Features & Design

• Mount-specific fit: cut for the Sky-Watcher Star Adventurer GTi saddle.
• Puts the powerbox at the saddle: on a small travel mount this is the difference between one 12 V cable running to the tripod and a bundle of them.
• 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 Avalon M-UNO and LINEAR.
• Mechanical only: no electronics, no ports, no effect on the Saddle Powerbox's outputs or sensors.

Recommended Uses

• Fitting a Saddle Powerbox to a Star Adventurer GTi for on-mount power and USB distribution.
• Travel and airline-luggage rigs where cable count matters as much as weight.
• 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 Sky-Watcher Star Adventurer GTi. The earlier Star Adventurer models are a different mount and are not named in Pegasus Astro's 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.
• Unsure which Star Adventurer you have? Send us a photo of the mount head and we will identify it with you.

Good to Know Before You Order

• The puck is mount-specific. This one is the GTi version; the HEQ5, AZ-EQ6, NEQ6/EQ6-R, CEM26/GEM28, AM5 and M-UNO 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 GTi is a small-payload mount. The powerbox sits above the saddle and counts toward what the GTi is carrying, alongside the telescope and camera — worth working into your payload budget before the first session.

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.

Will it fit the original Star Adventurer or the 2i?

Pegasus Astro names the Star Adventurer GTi for this puck. Tell us which model you have and we will check the range against it.

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.

Is a Saddle Powerbox overkill on a mount this size?

It comes down to how many devices you run. On a GTi carrying a small refractor, a camera, a dew strap and a guide camera, consolidating them onto the mount head is exactly the case the saddle format is built for.

Bottom Line

In short: the mount-specific adapter that puts a Pegasus Astro Saddle Powerbox onto a Sky-Watcher Star Adventurer GTi — one bolt-on part, and a travel rig that runs on a single cable to the ground.
