Supports a massive 220 lbs (100 kg) payload Lightweight 25.8 lbs (11.7 kg) aluminum and steel construction Adjustable height from 31.5" to 42.5" Wide 48.8" leg spread for maximum s tability Folds to a compact 26" length for transport Description FAQ Specifications In the Box Downloads Warranty iOptron Tri-Pier The iOptron Tri-Pier combines the rigid stability of a permanent pier with the portability of a field tripod, supporting an impressive 220 lbs payload on a frame that weighs only 25.8 lbs. Its 5.7" diameter central column and 48.8" maximum leg spread provide an exceptionally stable platform for large instruments, while the adjustable height range of 31.5" to 42.5" ensures comfortable viewing angles for any telescope. For serious imagers and visual observers, the Tri-Pier delivers the vibration damping needed for critical work, folding down to just 26" for transport to your favorite dark sky site. Rock-Solid Foundation: Supporting 220 lbs on a 25.8 lb Frame The core purpose of the Tri-Pier is to provide an unmoving base for your telescope mount. With a maximum payload of 220 lbs (100 kg), it can handle observatory-class mounts and heavy optical tube assemblies without flexure or vibration. Despite this immense capacity, the pier itself weighs only 25.8 lbs (11.7 kg), achieving a remarkable strength-to-weight ratio that traditional tripods cannot match. Central Column: The 5.7" (144 mm) diameter pier is the source of its rigidity, minimizing the torsional flex that can ruin long exposures. Wide Stance: The legs can extend to a 48.8" (1240 mm) diameter footprint, creating a low center of gravity that resists wind and accidental bumps. Top Plate: A 150mm top plate provides a broad, secure surface for attaching a wide variety of equatorial mounts. Field-Ready Design: 31.5" to 42.5" Height Adjustment Setting up in the field requires adaptability. The Tri-Pier's legs are independently adjustable, allowing you to achieve a perfectly level platform on uneven ground with a compensation range of up to 3.35" (85 mm). The overall height adjusts from 31.5" to 42.5", letting you set a comfortable eyepiece height whether you're using a short Schmidt-Cassegrain or a long refractor. Portable Stability: Folds to 26" for Transport Permanent-pier stability no longer requires a permanent installation. The iOptron Tri-Pier is designed for astronomers on the move, collapsing into a highly portable package. When folded, it measures a compact Ø12.8" x 26", making it easy to fit in the trunk of a car along with the rest of your imaging gear. This combination of robust field stability and easy transportability makes it an ideal choice for outreach events, star parties, and trips to remote observing sites. iOptron Tri-Pier vs. Standard Tripods: The Damping Advantage While a heavy-duty tripod can support a large payload, its primary weakness is vibration. A tripod's many joints and thin, extendable legs are prone to oscillating, especially in the wind or during focusing adjustments. The Tri-Pier's design is fundamentally more stable. Fewer Components: The solid 5.7" central pier and stout, triangulated legs have significantly fewer points of flexure than a tripod. Vibration Damping: The mass and rigidity of the pier structure absorb and dissipate vibrations much faster than a tripod. For an astrophotographer, this means fewer lost sub-exposures and sharper stars. Torsional Stability: The Tri-Pier excels at resisting twisting forces, which is critical for maintaining precise polar alignment and tracking accuracy throughout an imaging session. What kind of telescope setup can the iOptron Tri-Pier's 220 lb payload support? A 220 lb (100 kg) capacity allows the iOptron Tri-Pier to support nearly any commercially available amateur astronomy setup. This includes large Schmidt-Cassegrains (14" or 16"), long focal length refractors (6" or 7"), and heavy Newtonian reflectors on observatory-grade equatorial mounts with multiple guide scopes and imaging cameras. How does the iOptron Tri-Pier handle setup on an uneven surface like a backyard lawn? The Tri-Pier is designed specifically for such conditions. Each leg can be adjusted independently, allowing you to compensate for slopes and uneven ground. With an adjustment range of 3.35" (85 mm), you can achieve a stable, level base even on moderately inclined surfaces, ensuring your mount's polar alignment is accurate for imaging targets like the Orion Nebula (M42). Is the iOptron Tri-Pier's maximum height of 42.5" suitable for long telescopes like refractors? Yes, the 31.5" to 42.5" adjustable height range makes the iOptron Tri-Pier very versatile. For long refractors, extending the pier to its maximum height raises the eyepiece to a more comfortable position, especially when observing objects near the zenith. For Cassegrain-style telescopes, a lower height is often preferred for stability and easier access to the eyepiece. How portable is the iOptron Tri-Pier for travel to a dark sky site? Despite its massive payload capacity, the Tri-Pier is very portable. It weighs 25.8 lbs (11.7 kg) and folds down to a compact Ø12.8" x 26" cylinder. This makes it easy to handle and transport in a standard vehicle, offering a significant advantage over heavier and bulkier alternatives. What is the primary advantage of the iOptron Tri-Pier's 5.7" column over a tripod? The 5.7" (144 mm) diameter pier provides superior rigidity and vibration damping. Unlike tripod legs, which can flex and oscillate, the solid pier structure resists twisting forces (torsion) and settles vibrations almost instantly. This is crucial for long-exposure astrophotography, where even minor vibrations can blur star images. What mounts are compatible with the iOptron Tri-Pier? The iOptron Tri-Pier includes a 150mm top plate designed to be compatible with a wide range of iOptron mounts. With appropriate adapters (sold separately), it can also be used with mounts from other manufacturers. Always check the mount's base diameter and bolt pattern to ensure compatibility.
