68-Degree Ultra Wide Angle Eyepiece 15mm - Expansive Views

Our review of the 68-Degree Ultra Wide Angle Eyepiece (15mm) finds it best suited for amateur astronomers who want a noticeably wider view without changing their telescope setup. The single biggest reason to buy is the 68-degree apparent field, which opens up star clusters, the Milky Way, and lunar vistas in a way standard 50-degree eyepieces do not. With a compact 1.25 in aluminum barrel and multi element optics, the eyepiece balances portability and improved contrast for casual observing sessions and backyard astronomy.

Key Features

• 68-degree apparent field: Provides expansive views that make sweeping star fields and larger deep-sky objects easier to frame and enjoy.
• 15mm focal length: Delivers a useful medium-power view that suits planetary detail and richer field context for deep-sky targets.
• Fully green coated optics: Coatings improve light transmission and contrast, making faint details easier to see under good skies.
• 1.25 in aluminum barrel: A sturdy, lightweight barrel is internally blackened to reduce internal reflections and stray light for cleaner images.
• Filter-ready threading: The barrel is threaded to accept 1.25 in filters, allowing color and contrast enhancement for lunar and planetary observation.

Who It's For

This eyepiece is ideal for hobbyist observers who want a wider apparent field without committing to a large, heavy eyepiece collection. It works well on small to medium telescopes for lunar observing, open clusters, and scanning the Milky Way where a broad field helps with context.

It is less suitable for users who need extreme high-power planetary eyepieces or those seeking premium multi-element designs with very high-end glass; professionals and advanced imagers may prefer specialized eyepieces tailored for astrophotography or premium edge-to-edge sharpness.

Pros & Cons

Pros

• Wide 68-degree field opens up richer sky panoramas and makes target acquisition easier.
• Fully green coated optics enhance contrast and overall image quality during visual observing.
• Threaded, blackened 1.25 in aluminum barrel is durable and accepts common filters for flexible observing.

Cons

• Not aimed at high-end planetary imaging or those needing extreme edge-to-edge correction beyond casual visual use.

Specifications

Our Verdict
