  • CAA (Top Adapter with M54 Mount)

    The QHYCCD CAA is a dovetail adapter ring that provides an M54 threaded connection for compatible cameras, adding exactly 6mm of optical path length to your imaging train. This adapter is specifically designed for QHYCCD color cameras with a native 17.5mm back focus, such as the QHY600C and QHY410C, creating a secure and standardized mounting point for M54 spacers and other telescope accessories.

    Standardize Your Imaging Train: The 6mm M54 Adapter

    The primary function of the CAA is to convert the camera's native dovetail connection into an M54 thread. This allows you to build a rigid and reliable imaging train using common M54-threaded components. The adapter consumes a fixed 6mm of back focus, a critical measurement to factor into your optical calculations to ensure you can reach focus with your specific reducer or flattener.

    System Integration: Compatibility with QHYCFW3L and Color Cameras

    This adapter is the same component QHYCCD includes with its QHYCFW3L 7-position filter wheel, listed as the "CAA (Dovetail Ring to M54)". It serves as a direct replacement or as a standalone part for custom configurations. It is essential for achieving the correct spacing on a range of popular QHYCCD color cameras.

    • Compatible Cameras: The CAA is designed for use with the QHY600C, QHY410C, QHY367C, QHY128C, QHY247C, and QHY168C models.

  • What is the primary function of the QHYCCD CAA?

    The QHYCCD CAA is a mechanical adapter that converts the dovetail ring on certain QHYCCD cameras into a standard M54 female thread. This allows you to securely attach M54-threaded accessories like spacers, filter wheels, or off-axis guiders to your camera.

    How much back focus does the QHYCCD CAA add?

    The QHYCCD CAA adds exactly 6mm of optical path length. When attached to a camera with a native 17.5mm back focus (like the QHY600C), the total back focus from the CAA's M54 thread to the sensor becomes 23.5mm.

    Which QHYCCD cameras is the CAA adapter compatible with?

    The CAA is designed for specific QHYCCD color cameras that use the dovetail mounting system. Confirmed compatible models include the QHY600C, QHY410C, QHY367C, QHY128C, QHY247C, and QHY168C.

    I own a QHYCFW3L filter wheel. Do I need to buy the QHYCCD CAA separately?

    No, you likely do not. QHYCCD includes one CAA adapter in the box with the QHYCFW3L filter wheel. This part is offered separately as a spare or for users who are building custom imaging trains without that specific filter wheel.

    Can I use the QHYCCD CAA to connect my QHY168C to an M54 reducer?

    Yes. The CAA provides the necessary M54 female thread to start your connection. After attaching the CAA to your QHY168C, you can add M54 spacers to achieve the precise back focus distance required by your reducer or flattener.
