  • PrimaLuceLab Adapter ESATTO 4" for Takahashi FSQ-106EDXIV

    This PrimaLuceLab adapter enables the installation of the ESATTO 4" robotic focuser onto the Takahashi FSQ-106EDX astrograph (versions 3 and 4). With a precise optical thickness of 35mm, this adapter is engineered to ensure the total optical path of the ESATTO 4" matches the original Takahashi focuser's 100.5mm length, allowing you to reach perfect focus with your existing imaging train.

    A 35mm Adapter for ESATTO 4" Robotic Focuser Integration

    Designed specifically for the Takahashi FSQ-106EDX series (versions 3 and 4), this adapter provides the critical mechanical link to upgrade from the stock manual focuser. It replaces the original unit, creating a seamless and rigid connection for the large-format ESATTO 4" robotic focuser. This upgrade is the first step in converting your world-class astrograph into a fully automated imaging platform.

    Preserving the FSQ-106EDXIV's 100.5mm Optical Path

    The most critical function of this adapter is maintaining the telescope's precise back focus requirements. The Takahashi FSQ-106EDXIV is designed around a 100.5mm focuser thickness; this 35mm adapter, when combined with the ESATTO 4" focuser, precisely replicates that dimension. This guarantees that you can achieve sharp focus without needing additional, non-standard spacers or extenders.

    Building a Fully Automated System with ARCO and EAGLE

    This adapter is your gateway to the complete PrimaLuceLab ecosystem. By installing the ESATTO 4" focuser, you gain access to its 10 kg payload capacity and 102.2mm of clear aperture, ideal for heavy cameras and filter wheels. You can then integrate the ARCO 3" robotic rotator for automated field de-rotation and framing, and control the entire system remotely with an EAGLE all-in-one computer, creating a powerful, observatory-grade setup.

  • What is the purpose of this ESATTO 4" adapter for the FSQ-106EDXIV?

    This adapter allows you to remove the original manual focuser from your Takahashi FSQ-106EDX3 or FSQ-106EDXIV telescope and replace it with the much larger, higher-capacity PrimaLuceLab ESATTO 4" robotic focuser. This enables automated, computer-controlled focusing for astrophotography.

    Why is the 35mm thickness of this FSQ-106EDXIV adapter so important?

    The Takahashi optical design requires a specific distance for the focuser assembly, which is 100.5mm. This adapter's 35mm thickness is calculated to perfectly complement the body of the ESATTO 4" focuser, ensuring the combined unit matches that 100.5mm requirement. This allows you to reach focus correctly with your camera and other accessories.

    Will this PrimaLuceLab adapter work with a standard Takahashi FSQ-106 or FSQ-106ED?

    No, this adapter is not compatible with the standard FSQ-106 or earlier FSQ-106ED models. It is specifically designed for the mechanical interface of the Takahashi FSQ-106EDX3 and FSQ-106EDXIV astrographs only.

    What benefits does the ESATTO 4" focuser offer over the stock FSQ-106EDXIV focuser?

    The ESATTO 4" offers several key advantages for imagers:

    • Robotic Control: Allows for precise, repeatable focusing controlled by a computer.
    • High Payload Capacity: Supports up to 10 kg, easily handling heavy imaging trains with large cameras, filter wheels, and off-axis guiders.
    • Large Aperture: Features a 102.2mm clear aperture to prevent vignetting with full-frame sensors.

    Can I use the ARCO 3" rotator with this ESATTO 4" adapter on my FSQ-106EDXIV?

    Yes, but you will need an additional, specific adapter. PrimaLuceLab makes a separate 10.5mm thick adapter (PL3600416) designed to connect the ARCO 3" rotator to the ESATTO 4" focuser when installed on an FSQ-106. This adapter prevents the rotator from interfering with the telescope's internal field flattener.

    Is everything I need to install the ESATTO 4" on my FSQ-106EDXIV included with this adapter?

    This product is the adapter only. You will need to have the PrimaLuceLab ESATTO 4" robotic focuser itself. This adapter provides the mechanical connection between the focuser and the telescope tube.
