  • ZWO Gen 2 M54 x 0.75 Filter Drawer for 2" Filters

    The ZWO Gen 2 M54 Filter Drawer allows for quick, manual changes of standard 2" filters within your M54 threaded imaging train. The included M54 male to M48 female adapter plate creates a flexible connection to a wide range of full-frame cameras and field correctors, ensuring a secure, vignetting-free light path.

    Secure Magnetic Holder for 2" Filters

    Swapping filters in the dark is simplified by the magnetic filter holder, which snaps securely into the drawer body. For an even more robust connection, a side-mounted tension screw lets you adjust the fit, eliminating any possibility of movement or tilt that could compromise your flat frames or focus.

    M54 & M48 Threads for Full-Frame Imaging

    Native M54 x 0.75 male and female threads allow for direct integration into larger imaging trains common with full-frame sensors and large correctors. To maximize compatibility, ZWO includes an M54 to M48 adapter, letting you connect directly to the most common thread size found on ZWO full-frame cameras and other accessories.

    ZWO Filter Drawer Gen 2 vs. Gen 1

    This second-generation drawer introduces a significantly improved internal seal, a critical upgrade that reduces stray light and internal reflections during long exposures. The Gen 2 model also uses stronger magnets for a more positive and secure lock when the filter holder is inserted.

    • Improved Light Sealing: Reduces internal reflections and light leaks for cleaner long-exposure images.
    • Stronger Magnets: Ensure a firm, repeatable seating of the filter holder every time.
    • Compatibility Note: The Gen 2 drawer is only compatible with Gen 2 filter holders. It will not work with holders from the first-generation ZWO filter drawer.

  • What threads does the ZWO Gen 2 M54 Filter Drawer use?

    The drawer body has an M54 x 0.75 female thread on the telescope side and an M54 x 0.75 male thread on the camera side. It also includes an M54 male to M48 female adapter for connecting to M48-threaded cameras or accessories.

    Can I use my old ZWO Gen 1 filter holders with the Gen 2 M54 Filter Drawer?

    No. The ZWO Gen 2 M54 Filter Drawer is not backward-compatible. It is designed to work exclusively with the new Gen 2 filter holders due to changes in the design that improve light sealing.

    What size filters fit in the ZWO M54 Filter Drawer V2?

    The included filter holder is designed to accept standard 2" mounted astronomical filters, which use M48 x 0.75 threads.

    How do I connect the ZWO M54 Filter Drawer to my ZWO camera with M42 threads?

    This drawer is optimized for full-frame cameras with M54 or M48 threads. To connect to a camera with smaller M42 threads (common on APS-C or smaller sensors), you would need an additional step-down adapter, such as an M48-to-M42 adapter, placed after the included M54-to-M48 ring.

    I'm using an f/4 Newtonian with a full-frame camera. Will the ZWO M54 Filter Drawer cause tilt?

    The ZWO Gen 2 M54 Filter Drawer is designed to minimize tilt. The combination of strong magnets and the adjustable side tension screw creates a very rigid connection. By tightening the screw, you can eliminate any play between the holder and the drawer body, ensuring the filter remains orthogonal to the light path, which is critical in fast optical systems like an f/4 Newtonian.

    What is the small screw on the side of the ZWO Gen 2 M54 Filter Drawer body for?

    That is the tension adjustment screw. It allows you to increase the pressure on the inserted filter holder. This provides two benefits: it ensures a tight fit with zero movement for imaging, and it acts as a safety lock to prevent the holder from accidentally being pulled out.
