  • PrimaLuceLab GIOTTO 320 Smart Flat Field Generator

    The PrimaLuceLab GIOTTO 320 Smart Flat Field Generator provides a 320mm uniformly illuminated panel for capturing perfect flat frames with telescopes up to 290mm in aperture. Powered by a standard 12V source, it clamps securely onto tubes with external diameters from 287mm to 349mm and offers 100 steps of brightness control via USB-C, WiFi, or ASCOM for complete integration into any imaging workflow.

    Sun-Spectrum Illumination for Telescopes up to 320mm

    Achieving accurate color balance in your final image starts with high-quality calibration frames. The GIOTTO 320 uses an array of LEDs with a color temperature similar to the sun, combined with a specially designed diffuser to create an evenly illuminated field. This ensures your flat frames neutralize vignetting and dust spots without introducing any color cast, resulting in a clean, corrected image ready for processing.

    Secure Mounting for Tubes from 287mm to 349mm

    The GIOTTO 320 features a simple and secure mounting system using three plastic thumbscrews. This design allows you to attach the generator directly to the front of your telescope, fitting external tube diameters ranging from 287mm to 349mm. The plastic construction ensures your telescope's finish remains unscratched, while the firm grip eliminates the need to hold the panel by hand or repoint your telescope to the zenith for calibration.

    Total Control: USB-C, WiFi, and ASCOM Integration

    As a "smart" generator, the GIOTTO 320 offers multiple avenues for remote control. Connect it to your EAGLE or any Windows computer via its USB-C port for control through PrimaLuceLab's PLAY software or any ASCOM-compatible application. For computer-free operation, connect your smartphone or tablet to its built-in WiFi network and use the Virtual HandPad to set brightness, save presets for different filters, and recall them instantly.

    Automated Operation: Upgrade with the ALTO Motor

    For the ultimate in remote-observatory convenience, the GIOTTO 320 can be converted into a fully motorized, remote-controlled telescope cover. By adding the optional ALTO telescope cover motor, you can automate the entire process of opening your telescope for an imaging session and closing it with the GIOTTO in place, ready to take automated flat frames at the end of the night. This creates a seamless, hands-off workflow perfect for unattended imaging.

  • Will the GIOTTO 320 fit my Celestron EdgeHD 11" telescope?

    Yes. The Celestron EdgeHD 11" has an external tube diameter of approximately 298mm, which falls comfortably within the GIOTTO 320's supported range of 287mm to 349mm. The 320mm illuminated panel is also sufficiently large for the telescope's 280mm aperture.

    How can I automate flat frames with the GIOTTO 320 in my remote observatory?

    To fully automate your workflow, you can add the optional PrimaLuceLab ALTO telescope cover motor. This accessory physically attaches to the GIOTTO 320 and your telescope's dovetail bar, allowing you to remotely open and close it like a motorized lens cap. This is ideal for unattended observatories, enabling you to take flats at the beginning or end of a session without manual intervention.

    What software do I need to control the PrimaLuceLab GIOTTO 320?

    You have several options. You can use PrimaLuceLab's dedicated PLAY astrophotography software, any ASCOM-compliant software via the provided driver, or you can connect directly to the GIOTTO 320's WiFi network with a smartphone or tablet and use the web-based Virtual HandPad for control without a computer.

    How is the GIOTTO 320 powered?

    The GIOTTO 320 is powered by a standard 12V DC power source via a 5.5/2.1mm center-positive port. This allows you to power it from the same supply you use for your telescope mount and other accessories, minimizing cable clutter.

    Will the mounting screws of the GIOTTO 320 damage my telescope's tube?

    No. The thumbscrews used to secure the GIOTTO 320 to your telescope are made of plastic. This material is intentionally chosen to provide a firm grip without scratching or marring the finish of your optical tube.

    Can I adjust the brightness of the GIOTTO 320 for different filters?

    Yes. The brightness is digitally controlled and adjustable in 100 steps (from 0% to 100%). This fine control allows you to set the perfect illumination level for any filter, from broadband LRGB to narrowband, ensuring you can achieve your target ADU without oversaturating the camera sensor.
