  • Svbony 1.25" Telescope Eyepiece Adapter Coaxial Lock PETF Inner Ring

    The Svbony 1.25" Coaxial Lock Adapter securely connects M42 threaded accessories to any standard 1.25" focuser or visual back. Its coaxial locking mechanism provides a perfectly centered, 360-degree grip that outperforms simple thumbscrews, all within a lightweight 71.8g (2.53oz) body.

    Coaxial Lock with a 71.8g PETF Ring: Secure, Non-Marring Grip

    Unlike single-point thumbscrews that can push eyepieces off-axis or brass compression rings that can bind, this adapter's coaxial lock applies uniform pressure around the barrel. A simple twist of the blue collar activates the lock, centering your eyepiece or camera perfectly in the optical path. The internal contact surface is a durable PETF ring, which provides a firm hold without scratching or marring the finish on your 1.25" accessories.

    System Integration: Connect 1.25" Cameras to SV28, SV14, and SV13 Scopes

    This adapter is a key component for connecting Svbony cameras to Svbony spotting scopes for digiscoping. By pairing this adapter with a specific extension tube, you can achieve a solid, threaded connection for astrophotography or terrestrial imaging with your 1.25" camera.

    • For SV28 & SV14 Scopes: Use this adapter (F9164A) with the F9110A extension tube to connect 1.25" cameras like the Svbony SC001, SV105, or SV205.
    • For SV13 Scopes: Use this adapter (F9164A) with the F9162A extension tube to connect your 1.25" camera.

  • How does the Svbony Coaxial Lock Adapter improve on a standard thumbscrew adapter?

    A standard thumbscrew pushes an eyepiece or camera to one side, which can introduce tilt and misalignment in the optical path. The Svbony Coaxial Lock Adapter applies even, 360° pressure, ensuring the accessory is perfectly centered and parallel to the focal plane. This results in sharper images, especially during imaging.

    What is the benefit of the PETF inner ring on this M42 to 1.25" adapter?

    The PETF (Polyethylene Terephthalate) inner ring is a durable, non-metallic material that provides a secure grip without damaging your accessories. Unlike brass compression rings that can leave marks or metal thumbscrews that can dig into barrels, the PETF ring protects the finish of your eyepieces and cameras, keeping them in pristine condition.

    Will this 71.8g adapter add significant weight to my setup?

    No, at just 71.8g (2.53oz), the adapter is very lightweight and will not cause significant balance issues on most telescope mounts or spotting scope tripods. Its low weight makes it an ideal choice for portable and lightweight imaging setups.

    How do I connect my Svbony SV105 camera to my SV28 spotting scope using this adapter?

    To connect an SV105 camera to an SV28 spotting scope, you will need two components: this Svbony 1.25" Coaxial Lock Adapter (F9164A) and the Svbony F9110A extension tube. The extension tube threads onto the scope, and this adapter threads into the extension tube, providing a secure 1.25" port for your camera.

    I have an SV13 spotting scope. What else do I need besides the Svbony Coaxial Lock Adapter to attach a 1.25" camera?

    For the SV13 spotting scope, you will need this Svbony 1.25" Coaxial Lock Adapter (F9164A) and the Svbony F9162A extension tube. This specific combination provides the correct spacing and threading to connect a 1.25" camera to your SV13 scope.

    What does "M42" refer to on this 1.25" adapter?

    M42 refers to the thread specification on the telescope side of the adapter. It has a diameter of 42mm with a specific thread pitch. This allows it to connect to focusers, extension tubes, or other accessories that use this common M42 thread standard, converting them to accept standard 1.25" push-fit eyepieces and cameras.
