Explore Scientific U-Mount and Tripod for BT-150 Giant Binoculars

A pair of 150mm objectives weighs 41 lb, and at that mass every photo tripod and standard binocular mount becomes the weakest part of the system — the load rating runs out long before the shake does. The Explore Scientific U-Mount and Tripod is the answer Explore Scientific built for exactly that problem: rated to 110 lb (50 kg), roughly 2.7x the weight of the BT-150 ED it was designed to carry. The binocular sits nowhere near the limit of what is holding it, which is the whole point of a dedicated mount at this size.

Key Features

• 110 lb (50 kg) load capacity — the headroom is the feature. A mount loaded near its rating still technically holds the instrument, but it rings; a mount carrying less than half its rating damps out and settles fast, which is what you feel at high magnification.
• Purpose-built for the BT-150 — Explore Scientific designed this mount around their dual-150mm giant binocular. A conventional binocular mount is not engineered for two 150mm optical systems on one frame.
• U-fork design with field tripod — the mount and tripod ship together as one matched package, so there is no head-to-tripod compatibility question to solve.
• Explore Scientific Limited Lifetime Warranty — covered for the useful life of the product, with free adjustment and cleaning service available even beyond the warranty period.

Ideal For

• BT-150 ED owners who need the mount the binocular was actually specified against, rather than the largest photo tripod that will physically accept it.
• Observatory, club and outreach use, where a heavy binocular gets moved, pointed and re-pointed by many hands and needs to stay put between viewers.
• Long observing sessions — the fatigue in a big-binocular session usually comes from fighting the mount, not from the optics.

Accessories & Compatibility

• Pairs with the BT 150mm ED Giant Binocular, the instrument this mount was built for.
• Mounting a smaller pair? The U-mount with tripod for large binoculars covers binoculars with 70-120mm objectives and is rated to 26 lb (12 kg).
• Pairing this with a non-Explore Scientific binocular? Explore Scientific has not published a maximum binocular width for this mount, and we do not publish figures we cannot source. Contact us before ordering and we will confirm fit with the manufacturer first.
