  • Starizona Filter Adapter for 2" (M48) Holders

    This Starizona Filter Adapter ring is engineered to mount smaller filters into any standard 2" filter holder with M48x0.75 threads. With a 2" outer diameter, this adapter is designed specifically for the Starizona Filter Slider system but also works in many other M48 applications. It is available in three versions to accommodate 31mm unmounted, 36mm unmounted, or standard 1.25" mounted filters in your imaging train.

    Adapt M48x0.75 Threads for 31mm, 36mm, and 1.25" Filters

    This step-down ring allows you to integrate your collection of smaller filters into a 2" (M48) filter system. The adapter threads directly into any M48x0.75 female thread, instantly converting it to accept either a 31mm or 36mm unmounted filter, or a standard 1.25" threaded filter cell. The unmounted filter versions feature nylon retaining screws to hold the glass securely in place without causing damage.

  • What filter sizes does the Starizona Adapter support?

    The Starizona Filter Adapter is available in three separate options to fit different filter sizes. You can choose the version that fits 31mm unmounted filters, 36mm unmounted filters, or standard 1.25" mounted filters.

    What is the main purpose of this Starizona Adapter?

    Its primary purpose is to allow imagers to use smaller, more common filter sizes within a 2" filter holder that uses M48x0.75 threads. It was designed specifically for use with the Starizona Filter Slider system but can be used in other compatible hardware thanks to its standard 2" outer diameter.

    How are unmounted filters secured in the Starizona Adapter?

    The versions for 31mm and 36mm unmounted filters include nylon retaining screws. These screws hold the filter glass securely in the adapter without scratching or chipping it, ensuring a safe and stable fit.
