  • PrimaLuceLab Adapter from M110 to M98 with Stop Ring for ESATTO 4"

    Rotational Framing Control for ESATTO Imaging Trains

    This adapter provides the essential link between the large-format draw tube of the PrimaLuceLab ESATTO 4" robotic focuser and the common thread size used by many astrophotography cameras and accessories. It creates a secure, rigid connection, ensuring your imaging train remains free of flexure.

    The key feature is the integrated stop ring, which operates independently of the main adapter thread. This allows you to thread your camera or accessory into position, then adjust its rotational angle for perfect framing before locking it securely in place. This eliminates the need to repeatedly thread and unthread your camera to align your sensor with your target.

    • Secure Connection: Creates a solid, threaded attachment between the ESATTO 4" focuser and your imaging accessories.
    • Precise Rotational Adjustment: The independent stop ring lets you perfectly frame celestial objects by setting the camera angle without introducing tilt.
    • Minimal Optical Path: Engineered to add very little length to the imaging train, preserving critical back focus for correctors, filter wheels, or off-axis guiders.

  • What is the purpose of the PrimaLuceLab Adapter for ESATTO 4"?

    Its primary purpose is to connect an astrophotography camera or accessory that has a male accessory thread to the large female draw tube thread of the ESATTO 4" robotic focuser. It also includes a stop ring for precise rotational framing.

    How does the stop ring on this PrimaLuceLab adapter help with astrophotography?

    The stop ring is a separate, lockable collar. It allows you to thread your camera on, back it off slightly to achieve the perfect rotational angle for your target, and then tighten the stop ring against your camera to lock that position. This is crucial for composing mosaics or aligning your sensor to a specific orientation in the sky.

    Is this adapter designed to be low-profile?

    Yes, the adapter is designed to consume a minimal amount of optical path. This helps preserve as much back focus as possible, which is critical when using additional accessories like focal reducers, filter wheels, and off-axis guiders that have specific spacing requirements.

    When imaging a large target like the North American Nebula (NGC 7000), how does this adapter help?

    For large targets like the North American Nebula (NGC 7000), framing is critical. The adapter's stop ring allows you to rotate your camera sensor to fit the nebula's irregular shape within your field of view perfectly, ensuring you capture the entire object as intended without having to crop the final image.

    Can I use this adapter with a telescope like a Takahashi FSQ-106?

    You can use this adapter with any telescope, including a Takahashi FSQ-106, provided that the telescope is equipped with a PrimaLuceLab ESATTO 4" robotic focuser. The adapter is specific to the ESATTO 4" and will not thread onto other focusers.

    Will this PrimaLuceLab adapter fit other focusers?

    No, this adapter is specifically designed with threads to match the PrimaLuceLab ESATTO 4" focuser's draw tube. It is not compatible with other models of ESATTO focusers or focusers from other manufacturers.
