TS Optics High End Planetary HR 5mm 58° 1.25″ eyepiece
Are you looking for an eyepiece that truly shows what your telescope is capable of? The HR Planetary series from TS Optics belongs among the premium eyepiece lines that have been thoroughly tested and proven themselves in comparison with competing products. The 5mm focal length eyepiece with a 58° field of view is an ideal choice for detailed observation of planets, the Moon, and compact deep sky objects.
Exceptional image clarity and contrast
The TS Optics HR Planetary 5mm eyepiece is distinguished by outstanding image clarity and contrast, which numerous independent tests have confirmed as above average compared to eyepieces in a similar price range. A key advantage is the 16mm eye relief and 20mm exit pupil diameter - parameters that manufacturers usually reserve for higher-class models. As a result, this eyepiece provides a comfortable viewing experience without the unpleasant blackout effect when the eye moves even slightly.
All optical surfaces are equipped with fully multi-coated (FMC) anti-reflection coatings, which minimize light loss, suppress unwanted reflections, and ensure excellent contrast transmission. This is especially important when observing fine details - the atmospheric bands of Jupiter, craters on the Moon, or the structure of Saturn's rings.
A versatile eyepiece, not just for planets
Although the name suggests a planetary focus, the HR Planetary 5mm 58° eyepiece is a fully capable general-purpose tool. It is equally well suited for solar system objects - planets, the Moon, and comets - as it is for compact deep sky objects such as planetary nebulae, globular clusters, and galaxy cores. The short 5mm focal length provides high magnification that, under good seeing conditions, reveals details that a weaker eyepiece simply cannot show.
Designed for long observing sessions
The eyepiece was designed with comfort in mind during extended observing sessions. The well-constructed rubber eyecup can be adjusted to multiple positions. Thanks to the generous 16mm eye relief, there is no need to remove corrective glasses - observers who wear spectacles can use the full field of view without any compromise. The standard 1.25″ barrel diameter ensures compatibility with the vast majority of available telescopes.
