  • PrimaLuceLab GIOTTO 430 Smart Flat Field Generator

    The PrimaLuceLab GIOTTO 430 Smart Flat Field Generator provides a 430mm uniformly illuminated surface for telescopes with external tube diameters ranging from 392mm to 454mm. Powered by a standard 12V source, its sun-like LED array offers brightness control in 100 discrete steps via USB-C or WiFi. Designed specifically for reflector telescopes up to 390mm in aperture, it incorporates a 100mm central area to support its specialized light diffuser, making it an ideal tool for removing vignetting and dust artifacts from your images.

    430mm Uniform Illumination with 100-Step Control

    The GIOTTO 430 features a large, 430mm illuminated panel that ensures full coverage for large-aperture reflector telescopes. Its array of LEDs produces a color temperature similar to sunlight, while a specially designed diffuser guarantees even illumination across the entire surface. You can precisely adjust the brightness from 0 to 100% in 100 steps, allowing you to achieve the target ADU for your flat frames with any filter, from broadband LRGB to narrowband.

    Secure, Non-Marring Mounting for Tubes from 392mm to 454mm

    Attaching the GIOTTO 430 is straightforward and secure, using included plastic thumbscrews that grip your telescope's tube without scratching the finish. The design fits optical tubes with an external diameter from 392mm to 454mm. A 100mm non-illuminated central circle supports the diffuser and accommodates the secondary mirror obstruction of large reflectors. This design makes the GIOTTO 430 incompatible with refractor telescopes, which lack a central obstruction.

    12V Powered Smart Control: USB-C, WiFi, and ASCOM Ready

    Integrated electronics allow for complete remote control of the GIOTTO 430 from your preferred device. A USB-C port connects directly to a PrimaLuceLab EAGLE or any Windows computer for control via PLAY software or the dedicated ASCOM driver. For wireless operation, you can connect to its built-in WiFi network with a smartphone or tablet and use the Virtual HandPad to set brightness and save presets for different filter combinations, all powered by a common 12V DC input.

    ALTO-3 Ready: Upgrade to a Fully Motorized Telescope Cover

    For fully remote or automated observatories, the GIOTTO 430 can be transformed into a motorized telescope cover. By adding the optional ALTO-3 cover motor, you can remotely open and close the flat panel, protecting your optics from dust when not in use. This upgrade enables a completely automated workflow, allowing you to capture flat frames at the beginning or end of a session without ever touching the telescope.

  • Will the GIOTTO 430 work with my 14-inch SCT?

    Yes, the GIOTTO 430 is an excellent match for large Schmidt-Cassegrain telescopes. It is designed for tubes with an external diameter between 392mm and 454mm, and its 100mm central un-illuminated area is smaller than the secondary mirror obstruction of most large SCTs, ensuring proper flat field calibration.

    How do I control the GIOTTO 430 if I don't have a PrimaLuceLab EAGLE?

    You have two primary options for controlling the GIOTTO 430 without an EAGLE. You can connect it via its USB-C port to any Windows computer and use the ASCOM driver with your preferred imaging software, or you can connect wirelessly to its built-in WiFi network from a smartphone or tablet and use the web-based Virtual HandPad.

    Why can't I use the GIOTTO 430 with my large refractor telescope?

    The GIOTTO 430 is designed specifically for telescopes with a central obstruction, like reflectors, SCTs, and RCs. It has a 100mm non-illuminated circle in the center to support the diffuser panel. A refractor has no central obstruction, so this dark spot would be visible in your flat frames, making them unusable.

    Can I automate taking flat frames with the GIOTTO 430 using N.I.N.A. or SGP?

    Yes. By connecting the GIOTTO 430 to your computer via USB-C and using the dedicated ASCOM driver, you can control its brightness directly from ASCOM-compliant software like Nuit d'Astronomie (N.I.N.A.) or Sequence Generator Pro (SGP). This allows you to integrate flat frame capture into your automated imaging sequences.

    What is the optional ALTO motor and why would I need it for the GIOTTO 430?

    The ALTO-3 telescope cover motor is an optional accessory that attaches to the GIOTTO 430, converting it into a remotely operated, motorized dust cap. This is ideal for remote observatories, as it allows you to open and close your telescope and take flat frames without being physically present at the telescope.

    How is the GIOTTO 430 powered in the field?

    The GIOTTO 430 is powered by a standard 12V DC power source, the same type used by most astronomy mounts and cameras. This makes it easy to integrate into your existing field power setup without needing a separate or specialized power supply.
