  • Description

     Zhumell's Tachyon 25x100 Astronomical binocular is an industrial-strength, field-worthy instrument for astronomy. With 25x magnification, 100mm objective lenses, and a built-in tripod adapter, it offers plenty of power for observing craters on the moon and for picking out features on the planets. It'll even afford good views of interstellar objects.

    Plus, now the Zhumell 25x100 Tachyon binoculars take standard, 1.25-inch astronomical filters to enhance your views of the moon, planets, nebulae, and other celestial bodies. Ruggedly constructed and waterproof, the Tachyon will take just about anything nature can throw at it, and its locking, aluminum case will keep it secure on the road.

Customer Q&A

  • Q1: Does the L Mount for Binoculars require a bracket fitted to the binoculars to attach to a tripod or is it the bracket that directly attaches the binoculars to the tripod? If it is not, is there such an attachment available that will allow me to adapt a pair of binoculars to tripod use?

    A: The Binocular L-Mount attaches the binoculars directly to the tripod. There are no other attachments necessary.

  • Q2: Does this work with Nikon Action 12x50?

    A: Yes, the Zhumell L-Mount Tripod adapter will work just fine with Nikon Action 12x50 binoculars.

  • Q3: I have the Zhumell 20x80 Super Giant binocs and am considering ordering your Zhumell lightweight tripod. With these binocs and tripod is the L Mount Adaptor necessary, or just a nice to have item?

    A: You'll not need the L-Mount Adapter to use the Zhumell 20x80 SuperGiant Binoculars with the Lightweight Tripod. The binoculars will attach directly to the quick-release plate.

  • Q4: I wonder if this adapter can be used to attach to my nikon D70 digital SLR?

    A: i am sorry but no this is to attach a binocular to a tripod. You will want a camera adapter and what is called a T-ring. the T-ring will need to be for your specific camera.

  • Q5: What material is this bracket made from? Metal? Carbon?

    A: The Zhumell L-Mount Tripod Adapter is made of mild steel.

  • Q6: Would the Zhumell L-Mount Tripod adapter carry the weight of Celestron SkyMaster 25X100 ASTRO Binoculars ?

    A: Yes. This L-adapter is strong enough to support the weight of a 25x100 SkyMaster.
