  • William Optics Pier Mount 90

    The William Optics Pier Mount 90 provides an unshakable imaging platform with a massive 90 kg (198 lbs) loading capacity built upon a 100 mm (4") diameter aluminum alloy pillar. Weighing only 7 kg and standing at a working height of 89.3 cm, it delivers the stability of a permanent pier with the transportability required for field use, featuring 15 mm of fine leveling adjustment at each foot.

    A 90 kg Payload Capacity in a 7 kg Package

    The core design achievement of the Pier Mount 90 is its extreme strength-to-weight ratio. The 90 kg (198 lbs) load capacity supports even the largest commercially available telescope systems with dual-scope configurations and heavy imaging trains. At just 7 kg, the pier itself is easily transportable to remote dark-sky sites, eliminating the compromise between stability and portability.

    The 100mm Pillar: Engineering for Zero Flexure

    Unlike tripod legs, which can flex and vibrate independently, the Pier Mount 90's single 100 mm (4") diameter pillar provides superior torsional rigidity. This design is inherently more stable and damps vibrations faster, a critical factor for long-exposure astrophotography, especially in windy conditions. The aluminum alloy construction ensures that this rigidity is achieved without excessive weight, maintaining field usability.

    Field-Ready Ergonomics: 89.3 cm Height and 15mm Leveling

    Engineered for practical use, the pier's stance height of 89.3 cm offers a comfortable viewing position for most telescope types while keeping the system's center of gravity low. For setup on uneven terrain, each of the pier's feet includes 15 mm of precise height adjustment, allowing you to achieve a perfectly level platform without shims or guesswork. This ensures accurate polar alignment and tracking from any location.

    ZWO AM3/AM5 Ready with 3/8" Adapter

    The William Optics Pier Mount 90 is optimized for modern, high-performance mounts. It ships with a 3/8" thread adapter, making it a perfect drop-in solution for the popular ZWO AM3 and AM5 strain wave mounts. For users with other equatorial mounts, optional adapters are available, ensuring broad compatibility and making the Pier Mount 90 a long-term investment for your astrophotography setup.

  • What is the primary advantage of the William Optics Pier Mount 90 over a heavy-duty tripod?

    The main advantage is superior rigidity. The single 100 mm diameter pillar of the William Optics Pier Mount 90 resists twisting forces and damps vibrations much more effectively than the three separate legs of a tripod. This results in a more stable platform for long-exposure imaging, even with its massive 90 kg load capacity.

    How much load can the William Optics Pier Mount 90 handle for astrophotography?

    The William Optics Pier Mount 90 is rated for a substantial 90 kg (198 lbs) loading capacity. This is more than sufficient for large reflector or refractor systems, including dual-scope setups with heavy cameras, filter wheels, and guide scopes.

    Is the William Optics Pier Mount 90 compatible with my ZWO AM5 mount?

    Yes. The William Optics Pier Mount 90 includes a 3/8" thread adapter specifically designed for direct compatibility with the ZWO AM5, as well as the AM3. It provides a secure, seamless connection right out of the box.

    Can I use the William Optics Pier Mount 90 with mounts other than the ZWO AM3/AM5?

    Yes. While it comes standard with an adapter for ZWO mounts, the specification states that adapters for more EQ Mount types are optional. You can purchase different adapters to fit a wide variety of equatorial mounts from other manufacturers.

    How stable is the William Optics Pier Mount 90 for imaging with a large 11" SCT on a windy night?

    The William Optics Pier Mount 90 is an excellent choice for this scenario. Its 100 mm pillar provides exceptional resistance to the kind of low-frequency vibrations caused by wind that can ruin long exposures. With a 90 kg capacity, an 11" SCT is well within its stable limits, offering a significant improvement over most field tripods.

    I set up on uneven ground. How does the William Optics Pier Mount 90 help with leveling?

    The William Optics Pier Mount 90 is designed for field use on imperfect surfaces. Each of its feet has a 15 mm adjustable height range. This allows you to independently raise or lower each foot to achieve a perfectly level platform, which is essential for accurate polar alignment, without needing to carry extra leveling blocks.
