TS Optics Premium Flat Field 10.5mm 60° 1.25″ Eyepiece
A Premium Wide-Angle Eyepiece for Comfortable Observing
The TS Optics Premium Flat Field 10.5mm eyepiece delivers a wide 60° field of view, giving you a spacious and immersive view of the night sky. A 5-element, 4-group optical design ensures excellent correction across the entire field - even with fast optical systems. The rubber eyecup adds comfort during long observing sessions.
Fully Multi-Coated (FMC) glass surfaces maximise light transmission and reduce unwanted reflections, producing a bright, sharp and high-contrast image from edge to edge. The compact body weighs just 84 g, making it a practical choice for any observing night. The smooth, groove-free barrel sits securely in the focuser without tilting, ensuring stable and reliable holding.
Comfortable for Glasses Wearers
With 16mm of eye relief, this eyepiece works well for observers who wear glasses. You can see the full field of view without removing your glasses. The TS Optics Premium 10.5mm eyepiece suits both beginners and experienced observers who want reliable performance at a fair price. Solid build quality and quality materials ensure long-lasting use.
Versatile - What Can You Observe?
Deep Sky Objects
The FMC coatings make full use of your telescope's aperture. Nebulae, galaxies and star clusters - including fainter details in distant objects - become clearly visible.
Moon and Planets
The blackened interior barrel eliminates internal reflections, delivering high contrast and a clean, crisp image of the Moon and planets.
Double Stars
Fainter companion stars close to the primary star remain clearly visible - provided your telescope's resolution allows it.
Compatible with Afocal Photography
The compact, narrow barrel fits most standard afocal projection adaptors, making this eyepiece a useful tool for eyepiece projection astrophotography. It also works well for binocular viewing, thanks to its comfortable eye relief and consistent, symmetrical image across the full field of view.
