TS Optics High End Planetary HR 7mm 58° 1.25″ eyepiece
Are you looking for an eyepiece that can handle almost everything - from fine details on planetary discs and lunar surface structures to compact deep-sky objects? The TS Optics High End HR planetary eyepiece series was designed exactly with this goal in mind. The 7mm focal length combined with a 58° field of view makes this eyepiece a truly versatile tool, with no compromises made by the manufacturer in favor of cost or ease of production.
Optical quality and image performance
At the heart of this eyepiece is multi-layer coated optics that maximize light transmission while suppressing unwanted reflections and ghost images. The result is exceptionally high contrast and a sharp image, especially on the optical axis - a quality that is absolutely essential when observing planets. Every detail of Jupiter's cloud bands, Saturn's rings, or lunar craters appears with remarkable three-dimensional clarity. Galaxies and nebulae stand out clearly even against a moderately dark sky, thanks to the reduced light scatter.
Comfortable viewing experience
The designers of the HR series also paid close attention to observing comfort. The exit pupil reaches 16mm, and the diameter of the exit lens is 20mm - both values are above average. This means your eye does not need to be perfectly centered to see the full field of view. During long observing sessions, when fatigue begins to set in, this is a noticeable advantage. The soft rubber eyecup protects against stray light and keeps your eye at the correct distance from the lens without any physical effort on your part.
Astrophotography compatibility
The HR series eyepiece is fully compatible with projection photography using a DSLR or compact camera. The solid, precisely manufactured eyepiece body keeps the projection distance stable, which has a positive effect on image sharpness. For astrophotographers who want to capture details on the surface of planets or the Moon using afocal or projection photography, this is a reliable and capable choice.
Who is this eyepiece for?
The HR 7mm eyepiece is ideal for:
- Visual observers who require maximum contrast and sharpness without investing in the most expensive Japanese or American alternatives
- Astrophotographers looking for a quality eyepiece for planetary projection photography with consistent and predictable performance
- Anyone who wants one eyepiece that works well for both planetary and deep-sky observation
Thanks to the standard 1.25″ barrel diameter, this eyepiece fits the focuser of virtually any telescope available on the market.
