TS Optics High End Planetary HR 25mm 58° 1,25″ Eyepiece
The HR Planetary series carries the name "planetary", but in practice it covers a much wider range of uses. It works well for observing planets and the Moon, but it is equally at home when viewing deep-sky objects or performing projection photography. The name simply cannot describe everything this eyepiece can do.
Sharp image and comfortable viewing
When it comes to planetary and lunar observation, contrast and resolution are what matter most - especially on the optical axis. The HR Planetary delivers on both counts. The image is sharp, viewing comfort is high, and this allows you to follow fine surface details over longer sessions without unnecessary eye strain.
Outstanding light transmission and a natural field of view
The TS Optics HR Planetary eyepiece features multi-layer coatings on all air-to-glass surfaces, giving it exceptional light transmission. Compact deep-sky objects that are barely visible through other eyepieces appear bright and free of scattered light here. The 58° field of view provides enough space for context - the surrounding star field helps you orientate yourself, and the overall view feels natural and easy to read.
Versatile performance in one eyepiece
Whether you are studying the cloud belts of Jupiter, tracing the craters of the Moon, or picking out a faint galaxy cluster, the HR Planetary handles each task with confidence. It is a single eyepiece that genuinely earns its place in any telescope case.
