Omegon Cronus WA 3.2mm Eyepiece (1.25 inch)

Omegon Cronus WA 3.2mm Eyepiece (1.25 inch): Wide-angle eyepiece with 60-degree field of view

The Omegon Cronus WA 3.2mm is a wide-angle eyepiece with a 60-degree field of view and a 16mm eye relief. This focal length is just below the limit of what most medium-sized telescopes can handle in terms of magnification.

The Cronus series is the affordable entry into wide-field eyepieces: you see about 20 percent more field of view than with a standard Plossl, without a tunnel effect. Objects stay in view longer, which is especially nice with telescopes without a tracking motor.

Comfortable viewing, even with glasses

The 16mm eye relief is generous for this price range. Your eye doesn't need to be exactly on the optical axis to see a full field of view, virtually eliminating black vignetting. Those who wear glasses can observe with them on.

The rotating eyepiece can be adjusted to your preferred distance. Useful if multiple people are looking through the same telescope.

Six-element optics with multi-coating

The six-element lens design features multi-layer coating on all air-to-glass surfaces. This increases light transmission and keeps reflections low, for a high-contrast image with a dark background.

The 1.25-inch barrel has standard filter threads, so you can screw a moon filter or color filter directly under the eyepiece.

What do you see with 3.2 mm?

On a telescope with a focal length of 750 mm, 3.2 mm provides a magnification of 234x: suitable for lunar detail and planets under good atmospheric conditions.

You bring out structures in the cloud bands of Jupiter, the relief along the moon terminator, and the phase of Venus.

Featured accessories

All Cronus eyepieces share the same field of view and eye relief, making it comfortable to switch focal lengths. Combine with an Omegon Moon Filter (1.25 inch) to dim the bright lunar image, or with an Omegon Barlow lens for extra magnification at longer focal lengths.

For whom yes and for whom no

• ✓ Beginners and advanced users who want a wider field of view than a Plössl offers
• ✓ Spectacle wearers, thanks to the 16 mm interpupillary distance
• ✓ Telescopes without tracking motors: objects stay in view longer
• For those seeking a flat field of view all the way to the edge, the Omegon Flatfield series is better suited.
