  • Starizona Modular Filter Slider

    The Starizona Modular Filter Slider adapts to nearly any imaging train with its interchangeable M42, M48, and M54 plates. For systems requiring precise spacing, a 21mm "Tall" version is available to simplify achieving correct backfocus without extra adapters.

    A Configurable System with M42, M48, and M54 Plates

    The core of the Modular Filter Slider is its system of interlocking top and bottom plates. All plates use common, standardized threads, so you can match the slider's connections to your camera, focal reducer, or telescope. Instead of buying a new filter slider for each optical train, you can simply swap plates to adapt the unit as your equipment changes.

    The 21mm "Tall" Option for Simplified Spacing

    The standard Modular Filter Slider is 17.5mm tall. The "Tall" version uses a female threaded plate that is 3.5mm thicker, bringing the total height to exactly 21mm. This thickness fits cleanly into many common imaging trains, which can remove the need for separate spacer rings.

    Upgraded Light Sealing and Removable Drawer Knobs

    The new filter drawers and interlocking plates give better protection against light leaks, a critical improvement for long-exposure imaging. Every filter drawer now has a removable knob, which gives extra clearance in tight setups such as HyperStar systems or trains with little room between the camera and focuser.

    Modular vs. Original Filter Slider

    The Modular Filter Slider is a complete redesign and is not backward-compatible with the discontinued Starizona Original Filter Slider.

    • No cross-compatibility: filter drawers, top plates, and bottom plates from the Modular system do not fit the original slider.
    • Original parts don't fit either: original slider drawers and top plates do not work with the Modular body. Starizona still makes replacement drawers and tops for the original system.

  • What makes the Starizona Modular Filter Slider "modular"?

    Its modularity comes from the ability to interchange the top and bottom threaded plates. This allows you to customize the connections (M42, M48, M54) to match your specific camera, focuser, or other accessories, rather than being locked into a single configuration.

    What is the purpose of the 21mm "Tall" Starizona Modular Filter Slider?

    The 21mm "Tall" version is designed to help you achieve correct backfocus more easily. Many imaging systems require a specific amount of spacing, and the 21mm height of the "Tall" slider can often satisfy a significant portion of that requirement without needing additional, separate spacer rings.

    I have the original Starizona Filter Slider. Can I use my old filter drawers with the new Modular Filter Slider?

    No. The new Modular Filter Slider and its components (drawers, top plates, bottom plates) are not compatible with the original Starizona Filter Slider. You must use new Modular Filter Drawers with the Modular Filter Slider.

    How do I use the Starizona Modular Filter Slider with a HyperStar?

    To use the Modular Filter Slider with a HyperStar lens, you will also need a specific Filter Slider Adapter for your camera. This adapter is required to achieve the correct backfocus for the HyperStar system and provides the proper attachment point. These adapters are sold separately.

    Is a filter drawer included with the Starizona Modular Filter Slider?

    Yes. The slider comes with one filter drawer with a removable knob, plus a top plate, a bottom plate, six screws and an Allen wrench. Extra drawers are sold separately, so you can pre-load one drawer per filter.

    Do I need tools to change the plates on the Starizona Modular Filter Slider?

    Only the Allen wrench included in the box. The top and bottom plates attach to the body with six screws, which are also included.
