  • Pegasus Astro 2.1mm to 2.1mm Silicon Power Cables - 0.5m, 2 Pack

    This pack includes two 0.5-meter (1.6 feet) power cables designed to deliver a stable 5A current without failing in cold weather. Featuring standard male 2.1mm x 5.5mm connectors on both ends, these cables are engineered with a flexible silicon jacket that remains pliable long after standard PVC cables have turned rigid and brittle from the cold.

    5A Cold-Resistant Silicon Power Cables: Reliable Power at Any Temperature

    Standard vinyl-jacketed (PVC) power cables become stiff and difficult to manage as temperatures drop, creating a snag risk that can ruin an exposure or damage your equipment. These Pegasus Astro cables solve the problem with a high-quality silicon sheathing that stays flexible and easy to route, even in freezing conditions. The robust construction supports a continuous 5A current draw, ensuring your mount, camera, and accessories receive stable power throughout the night.

    • Cold-Weather Reliability: The silicon jacket is the key feature, preventing the brittleness that plagues common PVC cables during winter observing sessions.
    • High Current Capacity (5A): Safely power demanding equipment like cooled CMOS cameras, high-torque mounts, or multiple accessories through a power hub without voltage drop.
    • Universal Connector: The male 2.1mm x 5.5mm center-positive barrel connector is the industry standard for astronomical equipment, ensuring broad compatibility.
    • Convenient Length: At 0.5 meters (1.6 feet), these cables are ideal for short connections on your telescope rig, such as from a power box to a camera or focuser, minimizing cable clutter.

  • What is the main advantage of these Pegasus Astro silicon cables over standard power cables?

    The primary advantage is the silicon jacket. Unlike standard PVC or vinyl, silicon does not become stiff or brittle in cold temperatures. This makes the cables much easier to manage on a cold night and significantly reduces the risk of cracking or cable-related snags that can disrupt tracking.

    Will these 0.5m Pegasus Astro cables work with my ZWO ASIAIR or Sky-Watcher mount?

    Yes. The vast majority of modern astronomical equipment, including ZWO cameras and controllers, Sky-Watcher mounts, and Pegasus Astro's own power boxes, use the 2.1mm x 5.5mm DC barrel plug. These cables are designed to be universally compatible with that standard.

    Can I use these Pegasus Astro cables to power a cooled camera that draws more than 3A?

    Absolutely. These cables are rated for a maximum current of 5A, which is more than sufficient for even the most power-hungry cooled CMOS/CCD cameras, dew heaters, and electronic focusers. The 5A rating ensures safe operation without overheating or voltage drop.

    Why would I choose a short 0.5m cable for my telescope?

    A 0.5-meter (1.6 feet) cable is perfect for cable management on the optical tube assembly itself. It allows you to connect devices like a camera, focuser, or guide scope to a nearby power hub (like a Pocket Powerbox) without having long coils of excess wire that can snag on the mount as it slews.

    Are the connectors on these Pegasus Astro cables center-positive?

    Yes, they follow the standard center-pin positive convention used for nearly all astronomy gear. You can use them to connect any two devices that share the 2.1mm x 5.5mm connector size without worrying about polarity issues.

    I'm imaging in temperatures near freezing; will these 0.5m silicon cables become difficult to bend?

    No, this is precisely the scenario they are designed for. The silicon material is specifically chosen for its excellent performance in cold weather. It will remain soft and flexible, unlike typical plastic-coated cables that turn into rigid, uncooperative wires below freezing.
