The TS ED 18 is a medium magnification eyepiece for telescopes with a long focal ratio. On such telescopes it is very well suited for deep sky objects.
Advantages of TS PARAGON ED Eyepieces:
- ED Eyepieces offer excellent image sharpness and contrast with their 6-element design including an ED lens for best results.
- Excellent Eyepieces for Binoviewers - Paragon ED eyepieces have a slim body compared with many of today's wide angle eyepieces. This and the long eye relief make them perfect for use with binoviewers.
- Long Eye Relief: 20mm - There is no need to squeeze your eyepiece into a tiny lens. You can stay at a comfortable distance and still see the entire field of view. With eyeguard folded back you can see the full field with eyeglasses.
- Bright high contrast image. Multicoating. Blackened Interior - An excellent broadband multicoating on each glass-to-air surface and blackened lens edges provide for a bright, high contrast view without disturbing internal reflection.
- No false colour fringing - The ED glass element minimizes false colour fringing icaused by the eyepiece. Of course false colour created by the telescope will still be present.
- TS ED eyepieces are parfocal - When switching between eyepieces of this series refocusing is not necessary.
