TS Optics High End Planetary HR 9mm 58° 1,25″ Eyepiece
The name "planetary" does not fully reflect what this eyepiece can do. The HR Planetary performs equally well on planets and the Moon, but it also delivers excellent results on deep-sky objects and for afocal photography. This is a truly versatile eyepiece with a clear focus on image quality.
Sharp, high-contrast views of planets and the Moon
Planetary and lunar observation benefit directly from the very high contrast and sharpness this eyepiece provides, particularly on the optical axis. The image is clean and stable. Fine details - lunar landscapes, cloud belts on Jupiter, the rings of Saturn - are all visible without straining your eyes. Comfortable, relaxed viewing means you can stay at the eyepiece longer and notice more.
Deep-sky performance
Compact nebulae and galaxies place strict demands on optics. Faint surface brightness is easily lost to even slight light transmission losses or poor lens coatings. The HR Planetary uses multi-layer coatings on all air-to-glass surfaces. This keeps light transmission high and reduces reflections and scattered light to a minimum.
A 58° field of view at a 9mm focal length gives you a generous slice of sky. Compact objects no longer appear isolated - you can judge their size and position in relation to their surroundings with ease.
