  • ZWO 160mm Pier Extension for AM5 Mount

    The ZWO 160mm Pier Extension adds a critical 6.29 inches of clearance between your ZWO AM5 or AM3 mount head and tripod, preventing collisions with longer optical tubes during meridian flips. This simple, rigid extension is the definitive solution for imagers using long refractors or SCTs with extensive camera trains, enabling uninterrupted automated imaging sessions past the meridian.

    Add 6.29" of Clearance for Uninterrupted Imaging

    The primary function of the PE160 is to create 6.29 inches of vertical space, solving the common problem of a long optical tube assembly (OTA) or camera train striking a tripod leg. For automated imaging sequences that track an object across the sky, this additional clearance is not just a convenience—it's essential for capturing a complete data set without manual intervention or risking equipment damage.

    ZWO PE160 vs. PE70: Over 2x the Clearance

    While the earlier PE70 pier extension offers a more compact profile, the PE160 provides more than double the height. This makes the PE160 the superior choice for longer instruments where maximum clearance is the priority.

    • ZWO PE70: Provides 70mm of extension, suitable for shorter refractors or systems with compact camera setups.
    • ZWO PE160: Delivers 160mm (6.29") of extension, purpose-built for longer focal length refractors, larger SCTs, and complex imaging trains that demand the most space possible to clear the tripod.

    Rigid Assembly with 6 M6 Socket Head Cap Screws

    A stable mount is non-negotiable. The ZWO PE160's design uses three solid aluminum pillars bolted between two thick plates with six M6 socket head cap screws, forming a stiff, lightweight structure. This construction ensures that flexure is minimized, a critical factor when raising the center of gravity of your setup by 6.29 inches, preserving the tracking accuracy of your AM5 or AM3 mount.

  • Will the ZWO PE160 prevent my long refractor from hitting the tripod legs?

    Yes, this is its primary purpose. By adding 160mm (6.29") of height, the ZWO PE160 lifts the mount and telescope assembly, allowing the end of a longer optical tube or camera train to swing clear of the tripod legs during a meridian flip. This is especially crucial for refractors over 800mm focal length or SCTs with long dew shields.

    Is the ZWO PE160 compatible with the ZWO AM3 mount?

    Yes. The ZWO PE160 Pier Extension is fully compatible with both the ZWO AM5 and ZWO AM3 harmonic drive mounts, using the same mounting pattern.

    Can I use the ZWO PE160 with a tripod other than the ZWO TC40?

    While designed to seamlessly integrate with the ZWO TC40 carbon fiber tripod, the PE160 can be adapted to other tripods. You must ensure the third-party tripod has a compatible top plate and bolt pattern or that a suitable adapter is available to create a secure, stable connection.

    What is the benefit of the ZWO PE160 for my 8" SCT on an AM5 mount?

    For an 8" SCT, especially with a focal reducer and a long camera train (filter wheel, OAG, main camera), the back of the assembly can easily collide with the tripod during a meridian flip. The ZWO PE160 provides the necessary 6.29 inches of clearance to prevent this, allowing your automated imaging plan to run without interruption.

    How much height does the ZWO PE160 add to the mount?

    The ZWO PE160 adds exactly 160 millimeters, which is equivalent to 6.29 inches, of vertical height to your setup.

    Is the ZWO PE160 difficult to install?

    No, installation is straightforward. The package includes an upper plate, a bottom plate, three pillars, and all necessary hardware (6x M6 screws and a hex wrench). You simply bolt the pillars between the two plates and then attach the entire assembly between your tripod and mount head following the included quick guide.
