TS Optics High End Planetary HR 20mm 58° 1,25″ Eyepiece
The HR Planetary series carries the label "planetary", but its real range of use goes much further. It performs equally well on planets and the Moon as it does on compact deep-sky objects such as nebulae and galaxies. You can also use it for projection photography. The name is simply narrower than what this eyepiece can actually do.
Sharp detail and comfortable viewing
The HR Planetary eyepiece delivers high contrast and a sharp image, especially on the optical axis. This is exactly what you need when studying fine details in planetary atmospheres or on the lunar surface. Viewing is comfortable too - your eye does not tire quickly, so you can stay at the eyepiece longer and notice more.
Bright, clean views of deep-sky objects
Compact nebulae and galaxies are often faint, so every photon counts. Multi-layer coatings on all glass surfaces keep the image bright and clean, with no unwanted scatter. The 58° field of view shows a generous area of sky around the object at any given magnification, so the view never feels cramped.
Who is this eyepiece for?
This eyepiece suits observers who want one reliable eyepiece for a wide range of targets - from detailed planetary sessions to hunting faint deep-sky objects. It works well with any standard 1.25″ focuser.
