  • Starizona Filter Slider - Filter Blank

    The Starizona Filter Slider Filter Blank is a simple, essential accessory for astrophotographers, providing a solid, light-blocking disc with standard M48 filter threads. It is designed to function as a manual shutter, allowing you to capture crucial dark and bias calibration frames without introducing stray light.

    A Simple Shutter for M48 Filter Systems

    This filter blank is engineered for imagers using CCD cameras that lack a built-in mechanical shutter, such as many popular models from Atik and Starlight Xpress. It threads directly into any M48 x 0.75 filter holder, including the Starizona Filter Slider, occupying a slot just like a standard filter. Once in place, it completely blocks the optical path, enabling the capture of clean, uncontaminated dark frames. The blank is machined from anodized aluminum for durability and features a raised outer lip, making it easy to grip and handle, even with gloves on in the dark.

  • What is the purpose of the Starizona Filter Blank?

    The Starizona Filter Blank is designed to act as a manual shutter. It fits into a filter holder and blocks all light from reaching the camera sensor, which is necessary for taking dark frames and bias frames—two essential types of calibration files for astrophotography.

    Which cameras benefit from using the Starizona Filter Blank?

    This accessory is most useful for CCD cameras that do not have their own internal mechanical shutter. The manufacturer notes this includes many popular cameras from brands like Atik and Starlight Xpress.

    How does the Starizona Filter Blank attach to an imaging train?

    The Filter Blank has standard M48 x 0.75 filter threads. It installs into a filter holder, such as the one for the Starizona Filter Slider, in the same way you would install a normal imaging filter.
