  • PrimaLuceLab GIOTTO 150 Smart Flat Field Generator

    The PrimaLuceLab GIOTTO 150 Smart Flat Field Generator delivers a perfectly uniform 150mm field of illumination, powered by a 12V source and adjustable across 100 brightness steps. Designed to securely clamp onto any telescope with an outer tube diameter between 112mm and 174mm, it provides wired USB-C and wireless WiFi control to completely automate the capture of critical flat calibration frames.

    Uniform, Sun-like Illumination for Telescopes up to 150mm

    The core of the GIOTTO 150 is its array of LEDs, selected for a color temperature similar to natural sunlight, ensuring accurate calibration across all color channels. A specially designed diffuser panel guarantees the light is perfectly even across the entire 150mm surface, eliminating gradients and hotspots from your flat frames. This design is ideal for telescopes like refractors up to 120mm in aperture, effectively removing vignetting and shadows cast by dust motes in your optical train.

    Secure Mounting for Tubes from 112mm to 174mm

    Forget holding a panel by hand or pointing your telescope to the zenith. The GIOTTO 150 features three integrated plastic thumbscrews that allow you to lock the generator directly onto the front of your telescope. This secure, non-marring connection ensures the panel stays perfectly parallel to your optics throughout the capture sequence. The 112mm to 174mm clamping range accommodates a wide variety of compact refractors, Newtonians, and SCTs.

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

    As a "smart" generator, the GIOTTO 150 offers multiple layers of remote control. Connect it to your EAGLE or any Windows computer via its USB-C port for control through PrimaLuceLab's PLAY astrophotography software or any ASCOM-compatible application. For computer-free operation, connect directly to the GIOTTO's built-in WiFi network with your smartphone or tablet and use the Virtual HandPad to set brightness, save presets for different filters, and trigger exposures.

    Automated Operation: Add the ALTO Motor for a Remote Dust Cap

    For the ultimate in automation, the GIOTTO 150 can be paired with the optional ALTO telescope cover motor. This powerful upgrade transforms the flat field generator into a fully remote-controlled, motorized dust cap. From your control software, you can command the ALTO to open and close the GIOTTO, allowing you to capture flat frames automatically at the end of a session without ever touching the telescope—an essential feature for remote observatories.

  • How do I power the GIOTTO 150 flat field generator?

    The GIOTTO 150 runs on a standard 12V DC power source, the same voltage used by most telescope mounts and cameras. This allows you to easily integrate it into your existing power distribution system without needing a separate or specialized power supply.

    Can I control the GIOTTO 150 without a computer?

    Yes. The GIOTTO 150 has built-in WiFi connectivity. You can connect your smartphone or tablet directly to its WiFi network and use the included Virtual HandPad web app to turn the light on, set the brightness, and save presets for your different filters.

    What is the benefit of adding the ALTO motor to the GIOTTO 150?

    Adding the optional ALTO motor transforms the GIOTTO 150 from a manually-attached flat panel into a fully remote-controlled motorized dust cap. This allows you to automate your entire imaging workflow, including opening the telescope at the start of the night and closing it to take flat frames at the end, all without being physically present at the telescope.

    Will the GIOTTO 150 fit my Takahashi FSQ-106EDX4's 125mm dew shield?

    Yes, it will fit perfectly. The GIOTTO 150 is designed to clamp onto external tube diameters ranging from 112mm to 174mm. The included plastic thumbscrews will securely hold the unit onto your 125mm dew shield without scratching or damaging the finish.

    Can the GIOTTO 150 save different brightness settings for my LRGB filters?

    Absolutely. When controlling the GIOTTO 150 via the WiFi Virtual HandPad, you can create and save different brightness presets. This is ideal for users with multiple filters, as you can set the perfect brightness level for your L, R, G, B, and narrowband filters and recall them with a single tap, ensuring consistent flat frames every time.

    What software do I need to control the GIOTTO 150 from my Windows PC?

    You have two main options for PC control via the USB-C port. You can use PrimaLuceLab's free PLAY astrophotography software, which has a built-in wizard for calibration frames, or you can use third-party software like N.I.N.A. or Sequence Generator Pro via the dedicated ASCOM driver for the GIOTTO.
