  • ZWO 90 mm Holder Ring for ASI Pro Cooled Cameras

    The ZWO 90 mm Holder Ring provides a precise, secure mounting solution for ZWO cameras with a 90 mm body diameter, including the popular ASI2600 and ASI6200 Pro series. Two standard 1/4"-20 threaded holes and six M4 threaded holes in the base let you attach it to a tripod or dovetail plate.

    Secure 90 mm Fit for ASI2600 & ASI6200 Cameras

    This holder ring is purpose-built for the 90 mm diameter of ZWO's larger-format cooled cameras like the ASI2600 and ASI6200. The exact-fit design ensures a firm, no-slip grip around the camera body, delivering a more stable imaging platform than a single tripod-screw connection and reducing the risk of flexure or rotation during a long imaging session.

    1/4"-20 and M4 Threads in the Base

    The ring's base carries two standard 1/4"-20 threaded holes and six M4 threaded holes. Use them to attach the ring to a tripod or a dovetail plate.

    Choosing the Right ZWO Ring: 90 mm vs. 78 mm vs. 86 mm

    Selecting the correct holder ring is critical for a secure fit. ZWO produces several sizes for its camera lineup, and they are not interchangeable. This 90 mm model is specifically for their latest generation of large-sensor cameras; check your camera model against the list below before purchasing.

    • 90 mm Holder Ring (This Model): Correct for the ZWO ASI2600 and ASI6200 series cameras.
    • 86 mm Holder Ring: Required for larger body cameras such as the ASI094, ASI128, and ASI071 Pro.
    • 78 mm Holder Ring: Fits the mid-size ZWO cooled cameras, including the ASI1600, ASI183, and ASI294 Pro.

  • Which cameras are compatible with the ZWO 90 mm Holder Ring?

    This ring is designed exclusively for ZWO cameras with a 90 mm body diameter. This includes the ZWO ASI2600MM Pro, ASI2600MC Pro, ASI6200MM Pro, and ASI6200MC Pro.

    Will the ZWO 90 mm Holder Ring fit my ASI1600MM Pro camera?

    No. The ASI1600 Pro has a smaller body diameter and requires the ZWO D78 Holder Ring for a proper fit. Using the 90 mm ring would result in a loose, insecure connection.

    How do I attach the ZWO 90 mm Holder Ring to a dovetail bar?

    The base of the holder ring has two standard 1/4"-20 threaded holes and six M4 threaded holes. You can use a 1/4"-20 screw to bolt the ring directly to a Vixen or Losmandy style dovetail bar, which then slides into your telescope mount's saddle.

    Can I use the ZWO 90 mm Holder Ring to mount my ASI6200MC Pro and a camera lens for wide-field astrophotography?

    Yes, this is an ideal application. By attaching the 90 mm ring to a tripod or a small dovetail bar on a star tracker, you create a very stable platform for wide-field imaging with camera lenses. It supports the weight of the camera body directly, reducing strain on the lens mount.

    For my ASI2600MM Pro, is this 90 mm ring more stable than just using the camera's built-in 1/4"-20 hole?

    Absolutely. A single screw can act as a pivot point, allowing the camera to rotate slightly if bumped or as cables pull on it. The ZWO 90 mm Holder Ring clamps around the entire camera body, preventing any rotation and providing a much wider, more stable connection to your mount for improved tracking and stability.

    What tools are required to use the ZWO 90 mm Holder Ring?

    You will need a screwdriver or Allen key to attach the ring to your dovetail plate or tripod through its 1/4"-20 threads.
