  • ZWO 78mm Holder Ring for Cooled Cameras

    The ZWO 78mm Holder Ring provides a robust and reliable mounting solution for your 78mm diameter ZWO ASI cooled astronomy camera. This essential accessory ensures your camera is held securely, minimizing flexure and maintaining perfect alignment in your imaging train. Its precision CNC-machined construction guarantees a perfect fit, offering peace of mind that your valuable camera is protected and stable throughout long imaging sessions.

    Precision Machined for a 78mm Secure Fit

    Engineered specifically for ZWO's popular line of cooled cameras, this 78mm holder ring provides a snug and secure fit. The ring is opened by loosening a single, captive M6 screw, allowing you to easily place your camera inside. Once tightened, the ring clamps down firmly on the camera body, creating a stable connection that is critical for sharp, high-resolution astrophotography.

    Versatile Mounting with 1/4"-20 Threads

    Integration with your existing equipment is straightforward. The ZWO 78mm Holder Ring features standard 1/4"-20 female threads on both the top and bottom surfaces. This dual-mount design allows you to attach the ring directly to a tripod, a dovetail bar, or to stack other accessories like a guide scope on top, providing maximum flexibility in how you configure your deep-sky imaging rig.

    • Bottom 1/4"-20 Thread: Allows for direct attachment to tripods and universal dovetail plates for secure mounting to your telescope.
    • Top 1/4"-20 Thread: Perfect for piggybacking guide scopes or other accessories directly onto the camera assembly, keeping your setup compact and balanced.

    Broad Camera Compatibility for ZWO Imagers

    This holder ring is the standard mounting solution for a wide range of ZWO's most popular cooled cameras. If you own one of the cameras listed below, this 78mm ring is the correct accessory for secure mounting. Please note that it is not compatible with larger body cameras like the ASI071MC Pro or ASI2600 series, which require a larger ring.

    • Compatible With: ASI1600 Pro, ASI183 Pro, ASI294 Pro, ASI533 Pro, ASI178 Cooled, ASI174 Cooled, and ASI385MC Cooled cameras.
    • Incompatible With: ASI094, ASI128, ASI071 Pro, and ASI2600 cameras (these require the 86mm or 90mm holder ring).

  • How do I install my ZWO camera in the 78mm holder ring?

    Installation is simple. Locate the M6 screw on the side of the ring and loosen it until the ring can be opened. Gently place your 78mm ZWO cooled camera inside the ring, ensuring it is seated correctly. Then, tighten the M6 screw until the camera is held firmly in place. Do not overtighten.

    What do the 1/4"-20 threads on the ZWO 78mm Holder Ring let me do?

    The 1/4"-20 threads are a standard size for photographic and astronomical equipment. The thread on the bottom allows you to attach the ring to a tripod or a dovetail bar on your telescope mount. The thread on top allows you to mount accessories like a small guide scope or a WiFi adapter directly above the camera.

    Will this ZWO 78mm Holder Ring fit my ASI294 Pro camera?

    Yes, the ZWO 78mm Holder Ring is the correct size for the ASI294 Pro, as well as other 78mm body cameras like the ASI1600 Pro, ASI183 Pro, and ASI533 Pro. It provides a secure and stable mounting platform for these models.

    Is the ZWO 78mm Holder Ring compatible with non-ZWO cameras?

    This ring is specifically designed for ZWO cameras with a 78mm body diameter. While it might physically fit another brand's camera with the exact same diameter, proper fit and secure clamping are only guaranteed for the ZWO models listed in the compatibility section.

    Can I use this ring to mount my ASI1600 Pro and a lens to a tripod?

    Absolutely. This is a very common use case. By attaching this ring to your ASI1600 Pro, you can then mount the entire assembly to a standard photo tripod using the bottom 1/4"-20 thread, creating a stable wide-field imaging platform without a telescope.

    My camera is an ASI071MC Pro. Which ring do I need?

    The ASI071MC Pro has a larger body and is not compatible with this 78mm ring. You will need to purchase the larger ZWO 86mm Holder Ring for a proper fit.
