TS Optics WA 12mm 60° 1.25″ Eyepiece
The TS Optics TSWA12 wide-angle eyepiece with a 60° field of view and 12mm focal length covers the full range of visual astronomy - from surface details on the Moon and planets to compact nebulae, star clusters and double star splitting. It delivers a noticeably wider view than a classic Plössl or orthoscopic eyepiece, with no compromise in contrast or edge sharpness.
No built-in Barlow lens - full flexibility
Many wide-angle eyepieces include a built-in Barlow lens, which limits how you can use them with other accessories. The TSWA12 is designed without one. You can pair it freely with any Barlow lens to increase magnification without any optical compromise.
Optimised optics for brighter, sharper views
The WA series uses an optimised lens arrangement that increases image brightness and contrast. Edge distortion is kept to a minimum, so stars near the edge of the field look natural and well-defined. The eyepiece has a non-critical focus position, which means it works reliably with virtually any telescope. The fold-down eyecup makes it comfortable to use both with and without glasses.
