Omegon LE Planetary 5mm Eyepiece (1.25 inch)

Omegon LE Planetary 5 mm Eyepiece (1.25 inches): planetary eyepiece with 20 mm eye relief

The Omegon LE Planetary 5mm is a planetary eyepiece with seven lens elements, a 55-degree field of view, and a generous 20mm eye relief. A focal length for high magnification that is usable on medium-sized telescopes virtually every night.

LE stands for long eye relief: the series is designed for relaxed viewing at high magnifications. The eye relief of 20 mm remains the same across the entire series, so switching focal lengths does not require getting used to a different viewing position.

Built for Contrast

Seven lens elements with multi-layer anti-reflective coatings and a design that minimizes stray light: this results in a dark sky background and high contrast on planetary disks and the Moon.

The image is free from the kidney bean effect, the black shadow that appears with many eyepieces when your eye is not precisely on the axis.

20 mm interpupillary distance

With a 20-mm eye relief, you can use the binoculars while wearing glasses without losing any field of view. Even without glasses, the view is comfortable: you don't have to press your head against the eyepiece.

The 1.25-inch barrel has filter threads for moon and color filters.

What can you see with a 5 mm lens?

On a 150/750 Newtonian, 5 mm provides 150x magnification; on a 102/1000 Maksutov, 200x. This brings Jupiter’s cloud bands and Saturn’s rings into sharp focus.

Small planetary nebulae and the details in lunar craters also benefit from this magnification.

Featured accessories

The LE series ranges from 3 to 18 mm with the same field of view, so combining focal lengths as a set works well. An Omegon moon filter (1.25 inches) reduces the brightness of the moon’s image; an Omegon Barlow lens doubles the range of the longer focal lengths.

For whom yes and for whom no

• ✓ Planetary and lunar observers who prioritize contrast over maximum field of view
• ✓ People who wear glasses and anyone who spends long periods of time observing
• ✓ Owners of multiple focal lengths from the series: the view remains the same
• For those seeking the widest field of view for expansive deep-sky fields: choose the Omegon SWA or Redline series
• ✗ Smart telescopes without interchangeable eyepieces
