TS-Optics illuminable 26 mm 2" Crosshair Eyepiece This 26 mm Erfle eyepiece is a high-quality 2" overview eyepiece and a high-performance reticle eyepiece for exact centering of objects. By using this eyepiece, a small refractor with 2" focuser turns into a powerful finder with a little more magnification. The eyepiece is also perfectly suitable for GoTo telescopes for precisely centering reference stars.
The advantages - The crosshairs are laser-etched on an optical plate and very subtle. Even with the optional illumination, the crosshairs are only in slight contrast to the background and do not disturb the observation.
- With 70° apparent field of view and high-quality full multi-coating, the TSFK26 is also a full-fledged overview eyepiece, especially for faster telescopes.
- The 2" filter thread allows also the use of UHC filters etc.
- With rubber eyecup, foldable for spectacle wearers
- Comes with dust caps for the illumination connection at the side, the eye lens and the 2" barrel
Delivery contents- TS 26 mm 2" crosshair eyepiece with dust caps
