TS Optics 5 mm Planetary HR - 1.25" Eyepiece, 58°, fully multi-coatedHigh Resolution, long eye relief, wide angle planetary eyepieces
Planetary HR eyepieces were made for best possible image sharpness
particularly for observing planets. Contrary to other planetary
eyepieces such as Orthoscopics they have a much longer eye relief and a
larger field of view. Planetary HR eyepieces not only feature superb
image sharpness, but also a very high viewing comfort!Technical details
- Viewing Comfort: The Planetary HR eyepieces offer not only superb
image quality (see below), but also excellent viewing comfort. Eye
relief is much longer than in Orthoscopic eyepieces of similar focal
length. The eyepieces are suitable for eyeglass wearers.
The extendable rubber eyeguard offers individually perfect ergonomics for every observer.
- Optical Layout: Six elements offer a long eye relief, a large and
well corrected field of view, and above all superb image sharpness
throughout the field of view.
- Excellent Image Sharpness: On-axis image sharpness is practically
perfect, like a really good Orthoscopic eyepiece. Sharpness throughout
the field of view remains without visible deterioration. As a result the
eyepieces are considered by many to be even superior to Orthoscopics!
- Full Broadband Multi-Coating: Planetary HR eyepieces have a
broadband multi-coating on all glass-to-air surfaces. They have an
excellent transmission and contrast. Ghost images and internal
reflections are effectively suppressed.
- No Kidney-Beaning: Cheap eyepieces and too extreme wide angle
eyepieces often suffer from "Kidney-Beaning". When you move the head
only slightly a black, kidney-shaped shadow will cover a part of the
field of view. This effect is nearly eliminated in the Planetary HR
- Suitable for Use in Binocular Viewers: Planetary HR eyepieces are
very well suited for binocular viewing. You will have no trouble
looking through both eyepieces at the same time without getting into a
conflict with your nose. The adjustable eyeguard offers a perfect
observing position for critical binocular viewing.
