  • QHYCCD Adapter Kit - Combo D3

    The QHYCCD Adapter Kit - Combo D3 is an engineered solution for assembling a rigid and accurately spaced imaging train with specific QHYCCD cameras and accessories. This kit provides the adapters and spacers to connect a Nikon F lens at the 46.5mm back focus it requires. By using system-matched components, you eliminate the guesswork and potential for tilt that can arise from combining generic, third-party adapters.

    Combo D3: Achieving Precise Back Focus for QHYCCD Cameras

    A Nikon F lens only reaches infinity focus at its specified back focus, 46.5mm. The Combo D3 adapter kit is designed to provide this specific distance for a defined combination of QHYCCD equipment. This pre-calculated solution ensures your sensor is placed at the optimal focal plane, transforming your raw data with pinpoint stars from edge to edge.

    System-Matched Design: Eliminating Tilt with Rigid Connections

    A common source of image degradation is tilt, where the camera sensor is not perfectly perpendicular to the optical axis. The QHYCCD Adapter Kit - Combo D3 addresses this with screw-fixed QHYCCD adapters and spacers, creating a rigid connection from your camera to the lens. This solid assembly prevents the sensor shift and flexure common with compression fittings or mismatched adapters, preserving the optical alignment of your entire system.

  • What is the purpose of the QHYCCD Adapter Kit - Combo D3?

    The QHYCCD Adapter Kit - Combo D3 is designed to connect a Nikon F lens to specific QHYCCD color cooled cameras at the 46.5mm back focus Nikon lenses require. Its primary functions are to establish a secure, tilt-free connection and to set the precise back focus distance required by Nikon F lenses.

    How do I know if the Combo D3 kit is correct for my QHYCCD camera?

    QHYCCD produces different adapter kits for its wide range of cameras and accessories. To verify if the Combo D3 is the correct kit for your specific setup (it is listed for the QHY600C-PH, QHY268C version before 2023, QHY168C, QHY247C, QHY128C, QHY410C and QHY367C), it is essential to consult the official mechanical connection diagrams provided by QHYCCD. These charts illustrate the exact adapters needed for various equipment combinations.

    Why should I use the QHYCCD Adapter Kit - Combo D3 instead of generic adapters?

    While generic adapters can sometimes connect components, they often fail to provide the exact back focus spacing required for sharp images. Furthermore, the QHYCCD Combo D3 kit ensures a perfect mechanical fit with tight tolerances, creating a rigid, screw-fixed train that minimizes tilt and flexure, which are common problems with mix-and-match solutions.

    Will the QHYCCD Adapter Kit - Combo D3 work with accessories from other brands?

    This kit is specifically designed for the threads, body depths, and spacing requirements of QHYCCD products. While some components may share common threads (like M54 or M48), compatibility with third-party accessories is not guaranteed and may result in incorrect spacing or insecure connections.

    Does the Combo D3 kit allow for filter installation?

    Yes, but not with a filter wheel: QHYCCD designs Combo D3 for color cameras used without one. The kit includes a 2.5mm 2-inch filter fixer that holds a 2-inch UV/IR cut filter. With the camera and the kit's parts, the full 46.5mm is used, so there is no space for a filter wheel.

    I use an off-axis guider with my QHYCCD camera. Is the Combo D3 kit compatible?

    No OAG fits in the Combo D3 train. The camera body and its CAA (17.5mm + 6mm) and the kit's parts already add up to the 46.5mm a Nikon F lens needs.
