Get ready to revolutionize your planetary viewing! We're thrilled to introduce the 1.25" 20mm 58-degree BST Wide-Angle Eyepiece, a game-changer for anyone who loves observing planets and other celestial wonders.

Second only to our BST Starguider ED range, this remarkable eyepiece is engineered on the same construction as the legendary TMB Planetary eyepiece range.

This eyepiece is engineered for one purpose: to deliver stunning, crystal-clear views. Forget about the blurry edges and distracting colour distortion you've seen with other eyepieces. Our BST eyepiece is specifically designed to eliminate lateral colour aberration and light scatter, giving you an unparalleled level of detail and definition across the entire field of view.

Designed for Excellence

  • Super-Wide 58-Degree Field of View: See more of your target at once. This is especially fantastic for Dobsonian telescopes and non-tracking mounts, where objects drift across the view. Now you'll have more time to observe without constantly repositioning your scope!  The wide angle view gets more of the surrounding sky into your view putting celestial objects into context.  Star clusters are shown in all their glory.

  • Premium Optics: Featuring 5 elements and fully broadband multicoated glass, this eyepiece ensures maximum light transmission for the brightest, sharpest images possible.

  • Twist-Up Eyecup: Get the perfect fit with a twist-up eyecup that extends up to 7mm. This feature lets you easily adjust the eye relief for a comfortable viewing experience, even if you wear glasses.

How to Calculate Magnification

It's simple! Just divide your telescope's focal length by 20mm. For example, a 1200mm focal length scope gives you 60x magnification, while a 700mm scope provides a powerful 35x magnification.

Take your planetary observations to the next level and see the cosmos in a whole new way. You won't be disappointed!
