  • ZWO 2" Filter Holder (Gen 2)

    The ZWO 2" Filter Holder (Gen 2) is the essential accessory for any imager using ZWO's second-generation filter drawers, allowing you to pre-load every 2-inch (50.8mm) filter in your collection for immediate use. Each holder features standard M48x0.75 threads to secure your round mounted filters, eliminating the need to thread and unthread them in the dark. This system streamlines your imaging workflow by turning a multi-filter session into a simple slide-and-click process, backed by a 2-year warranty.

    Streamline Filter Changes with Pre-Loaded 2" Holders

    Stop fumbling with threaded filters in the dark. By purchasing individual ZWO Gen 2 holders, you can assign one to each of your 2-inch (50.8mm) filters. This allows you to prepare your entire filter set before an imaging session begins. When it's time to switch from a light pollution filter to a narrowband filter, you simply eject one holder and slide the next one in, saving valuable imaging time and reducing the risk of dropping a filter.

    Critical Compatibility for Gen 2 ZWO Drawers

    This filter holder is specifically engineered for ZWO's second-generation filter drawer systems. It is crucial to verify your drawer model before purchasing, as this holder is not backward-compatible with any first-generation ZWO filter drawers. Secure and precise seating is guaranteed only with the correct generation hardware.

    • Compatible With: ZWO Gen 2 M42/M48 Filter Drawer and ZWO Gen 2 M54 Filter Drawer.
    • Not Compatible With: Any first-generation ZWO M42, M48, or M54 filter drawers.
  • Will this ZWO Gen 2 Filter Holder fit my original ZWO M42 filter drawer?

    No. This is a critical point of compatibility. The Gen 2 holder is designed with different tolerances and will not fit or function correctly in any of the first-generation ZWO filter drawers. You must have a Gen 2 M42/M48 or Gen 2 M54 filter drawer to use this holder.

    What size filters does the ZWO 2" Filter Holder accommodate?

    This holder is designed for standard mounted 2-inch (50.8mm) round filters. It uses the standard M48x0.75 female thread to secure the filter into the holder.

    How does the ZWO Filter Holder system improve my imaging workflow?

    Instead of unscrewing a filter from your imaging train and carefully screwing in another one in the dark, you can pre-load all your filters into individual holders. Swapping filters becomes a quick, tactile process of sliding one holder out and another in. This is especially useful for LRGB or narrowband imaging sequences where you change filters frequently.

    Are the threads on this ZWO Filter Holder standard for all 2" astronomy filters?

    Yes. The holder features internal M48x0.75 threads, which is the industry standard for 2-inch mounted astronomy filters. Any standard, mounted 2-inch filter from any major brand should thread in without issue.

    I have a ZWO ASI camera and a ZWO Gen 2 M54 filter drawer. Is this the correct spare holder?

    Yes. This 2" holder is the correct model for the ZWO Gen 2 M54 filter drawer. It is also the correct holder for the Gen 2 M42/M48 model.
