  • PrimaLuceLab GIOTTO 185 Smart Flat Field Generator

    The PrimaLuceLab GIOTTO 185 Smart Flat Field Generator provides a 185mm uniformly illuminated panel to help you capture perfect flat frames for telescopes like refractors up to 150mm in diameter. It securely mounts to tubes with an external diameter from 147mm to 210mm and offers precise brightness control over 100 steps via its integrated USB-C and WiFi interfaces. Powered by a standard 12V source, the GIOTTO 185 integrates seamlessly into your existing astrophotography setup to eliminate vignetting and dust artifacts from your final images.

    GIOTTO 185: Uniform Illumination for Telescopes up to 150mm

    Achieving a perfectly calibrated image requires a flat frame with even, consistent lighting. The GIOTTO 185 uses an array of LEDs with a color temperature similar to the Sun, passed through a specially designed diffuser to create a flawless field of illumination. With an illuminated diameter of 185mm, it is ideally suited for compact telescopes such as refractors up to 150mm in aperture, ensuring the entire optical system is covered.

    Secure Mounting for Tubes from 147mm to 210mm

    The GIOTTO 185 attaches directly to the front of your telescope using three plastic thumbscrews, accommodating external tube diameters from 147mm to 210mm. This secure, non-marring connection means you no longer need to hold a panel by hand or point your telescope away from your target to capture flats. Once attached, it stays firmly in place throughout your calibration sequence.

    100-Step Control via USB-C, WiFi, and ASCOM

    As a smart device, the GIOTTO 185 gives you multiple pathways for remote control. Connect it to a PrimaLuceLab EAGLE or any Windows computer via its USB-C port to use the PLAY astrophotography software or a dedicated ASCOM driver. For wireless operation, connect your smartphone or tablet to the GIOTTO's WiFi network and use the Virtual HandPad to adjust brightness across 100 discrete steps and save presets for different filters.

    12V Power and Full Automation with ALTO

    Designed for field use, the GIOTTO 185 runs from a standard 12V DC power source, sharing the same supply as your mount and cameras. For the ultimate remote observatory convenience, you can add the optional ALTO telescope cover motor. This accessory transforms the GIOTTO into a fully motorized, remote-controlled dust cap, allowing you to automate the entire process of opening your telescope and capturing calibration frames without ever leaving your computer.

  • Will the PrimaLuceLab GIOTTO 185 fit my Celestron 8" EdgeHD telescope?

    No. The GIOTTO 185 is designed for telescopes with an external tube diameter between 147mm and 210mm. A Celestron 8" SCT or EdgeHD has an external diameter larger than this range, so you would need a larger GIOTTO model to ensure a proper fit.

    How do I control the brightness of the GIOTTO 185?

    The GIOTTO 185 offers three primary control methods for its 100-step brightness adjustment:

    • USB-C Cable: Connect to an EAGLE or Windows PC to use PrimaLuceLab's PLAY software.
    • ASCOM Driver: Use the dedicated ASCOM driver to control it with other Windows-based astrophotography software like N.I.N.A. or SGP.
    • WiFi & Virtual HandPad: Connect your smartphone or tablet directly to the GIOTTO's WiFi network to control brightness wirelessly.

    Can I automate my flat frame capture with the GIOTTO 185?

    Yes. By adding the optional ALTO telescope cover motor, the GIOTTO 185 can be converted into a remotely controlled motorized cap. This allows you to programmatically open and close your telescope and run your flat calibration sequence without being physically present at the telescope.

    Is the GIOTTO 185 suitable for my 130mm f/7 refractor?

    Yes, the GIOTTO 185 is an excellent choice. Its 185mm illuminated panel is larger than your telescope's 130mm aperture, ensuring full and even illumination for flat frames. You should measure the outer diameter of your telescope's dew shield to confirm it falls within the GIOTTO's 147mm to 210mm mounting range.

    What software do I need to use the PrimaLuceLab GIOTTO 185 with my computer?

    You can use PrimaLuceLab's PLAY astrophotography software, which is designed for seamless integration and includes a calibration wizard. Alternatively, you can install the provided ASCOM driver to control the GIOTTO 185 with most other ASCOM-compatible Windows imaging suites.

    Do I need a separate power supply for the GIOTTO 185?

    No, the GIOTTO 185 runs on a standard 12V DC power source. This allows it to be powered by the same portable battery or power supply that you use for your telescope mount, camera, and other accessories, simplifying cable management in the field.
