68-Degree Ultra Wide Angle Telescope Eyepiece 6mm - Expansive Views

In this review the 68-Degree Ultra Wide Angle Eyepiece 6mm is assessed for serious hobbyist stargazers who want a compact, high-magnification option for planetary and lunar work. The bottom line: this eyepiece delivers a noticeably wide apparent field and sharp images for its size, making it a solid choice when peak magnification and contrast matter. Our review found the multi element design and green coating produce pleasing color correction and usable contrast, while the threaded aluminum 1.25in barrel makes filter use and mounting straightforward.

Key Features

• 6mm focal length: Provides high magnification for close views of the moon and planets while still remaining usable on small to medium telescopes.
• 68-degree apparent field: Offers an expansive view that helps track tight targets and frames star clusters with less eyepiece movement.
• Fully green coated optics: Coating improves light transmission and reduces internal reflections for better contrast on faint details.
• Multi element design: Delivers sharper images with improved color correction compared with simple single lens eyepieces.
• Aluminum 1.25in barrel: Robust, lightweight barrel is internally blackened to cut stray light and is threaded to accept standard 1.25in filters.

Who It's For

This eyepiece is best suited to amateur astronomers who already own a 1.25in focuser and want a compact, high-power option for lunar, planetary, and bright deep-sky observing. Its 6mm focal length and wide 68-degree field make it useful for experienced users who can benefit from higher magnification while keeping a wider apparent view than typical narrow eyepieces.

Beginners or those using very small aperture telescopes should look elsewhere if they need lower magnification or brighter exit pupils for extended deep-sky observing; the 6mm focal length is inherently demanding on seeing conditions and telescope aperture.

Pros & Cons

Pros

• Wide 68-degree apparent field gives a more immersive view than narrow high-power eyepieces.
• Green fully coated multi element optics provide good color correction and improved contrast.
• Threaded, internally blackened aluminum 1.25in barrel accepts filters and reduces stray light.
• Compact and lightweight, easy to carry as part of an eyepiece kit.

Cons

• 6mm focal length is high magnification and may show atmospheric seeing limitations on poor nights.
• Not ideal as a single do-it-all eyepiece for wide field deep-sky viewing due to its short focal length.

Our Verdict

The 68-Degree Ultra Wide Angle 6mm eyepiece is a practical high-power option for observers who need crisp, contrasty views of the moon, planets, and compact star fields. Its combination of a wide apparent field, multi element optics, and a threaded, blackened 1.25in barrel makes it good value for users who already own medium to large aperture telescopes and want a dedicated high-magnification eyepiece.

Frequently Asked Questions

Will this eyepiece fit my telescope?
It fits any telescope with a standard 1.25in focuser or adapter because the barrel is 1.25in.

Can I use filters with this eyepiece?
Yes, the aluminum barrel is threaded to accept standard 1.25in filters for lunar and planetary contrast enhancement.

Is this eyepiece good for deep-sky views?
The 6mm focal length is best for high magnification targets; wider field eyepieces are preferable for broad deep-sky objects.
