  • Daystar USB Serial Cable - 2m

    The Daystar USB Serial Cable is the essential link for controlling your Daystar Quantum filter directly from a computer. With this USB-to-DB9 serial adapter, your computer communicates directly with Daystar's Quantum Control software, allowing for precise, on-screen adjustments to your filter's bandpass for maximum solar detail.

    Direct PC Control for Daystar Quantum Filters

    This cable connects your Quantum filter's DB9 serial port directly to a modern computer's USB port. It is the required interface for using the Quantum Control software. This application gives you a graphical interface for precise digital tuning of the filter's etalon, which is critical for dialing in the exact bandpass for optimal contrast on solar features like prominences and surface granulation.

  • What is the Daystar USB Serial Cable used for?

    It connects a Daystar Quantum series solar filter to a computer's USB port. This allows you to control the filter's tuning electronically using the Daystar Quantum Control software instead of the standard hand controller.

    Is this Daystar USB Serial Cable compatible with all Daystar filters?

    No, this cable is specifically designed for the Daystar Quantum series filters that feature a DB9 serial port for computer control. It is not intended for other Daystar products like the Quark series.

    Do I need special drivers for the Daystar USB Serial Cable?

    Yes, like most USB-to-Serial adapters, this cable may require a driver to create a virtual COM port on your Windows computer. The necessary drivers are typically included with the Quantum Control software or can be found on the Daystar Filters website.

    I want to automate my solar imaging session with a Daystar Quantum filter. Is this cable all I need?

    This cable is the essential hardware link between your filter and your PC. To automate your session, you will also need the Daystar Quantum Control software running on your computer. This setup allows you to precisely script or manually adjust the filter's bandpass to target different features on the Sun's chromosphere.

    Can I use this Daystar cable to control my Quantum PE filter while imaging prominences with my 100mm f/7 refractor?

    Absolutely. This is a perfect use case. By connecting your Quantum PE filter to a computer with this cable, you can make fine, repeatable tuning adjustments from your screen without touching the telescope. This minimizes vibrations and helps ensure you achieve the highest possible contrast on delicate solar prominences.

    My computer doesn't have a DB9 serial port. How do I connect my Quantum filter?

    This cable is the solution. It adapts the filter's DB9 serial connector to a standard USB Type-A port found on all modern laptops and desktop computers, bridging the gap between legacy and current hardware.
