Astromania’s premium flat field eyepieces provide remarkable image sharpness across the entire field of view, extending all the way to the edges. Featuring a blend of top-notch optics and high-quality coatings, these eyepieces stand out as a must-have for enthusiasts.

Key Advantages:

The 1.25" eyepieces deliver an exceptionally flat field of view right to the edges, ensuring a vibrant and sharp image without the need for refocusing when switching eyepieces.
They come with fully adjustable eyecups, making them particularly comfortable for extended observing sessions.
The eyepieces feature generously sized eye lenses, offering excellent eye relief for users, including those who wear spectacles.

Constructed from black anodized aluminum, the housing is both robust and durable. The standard 1.25" eyepiece barrel includes threads for 1.25" filters, while the elegant silver lens barrel features a safety undercut, minimizing the risk of slipping out of your telescope or diagonal. Furthermore, the blackened edges of the lens effectively reduce reflections, maximizing contrast.

Corrected Field Curvature for Optimal Observing

Astromania’s premium flat field eyepieces correct field curvature, a common optical flaw that can limit viewing experiences. This crucial correction allows for the entire field of view to be used effectively. Observers will appreciate the enhanced sharpness of images—not only at the center but clearly extending to the edges. This feature enables users to see natural objects exactly as they exist in reality.

Multi-Coating for Crystal-Clear Images

Prepare to be impressed by the exceptional clarity provided by the large eye lenses. The moment you look through these eyepieces, the crystal-clear images will further captivate you. Comprising 5-6 high-quality lens elements, these eyepieces ensure excellent light transmission, producing images characterized by high color purity and outstanding contrast.

Adjustable Twist-Up Eyecups for Comfort

The eyepieces are designed with solid, infinitely adjustable eyecups, allowing you to easily set your preferred viewing distance—perfect for long sessions of stargazing. Available in various models, with focal lengths of 8mm, 16mm, and 19mm, they are also well-suited for spectacle wearers.

Wide Field of View: 58° to 65°

Imagine observing an extended astronomical object through one of these eyepieces, as opposed to a standard Kellner or Plössl design. For instance, when viewing the Lagoon Nebula through an 8" f/5 Newtonian telescope, standard eyepieces might leave the object extending beyond the field of view. In contrast, any of these wide-angle eyepieces around 19mm will encompass the entire object. This is due to their 20-30% larger fields of view compared to standard eyepieces.

Durable and Elegant Design

Not only do these premium flat field eyepieces deliver top performance, but they also boast an elegant aesthetic. The anodized aluminum housing ensures resistance and longevity, while a rubber coating offers a convenient grip.

Experience the beauty and precision of Astromania’s premium flat field eyepieces—where sharp, clear imaging meets durable design for a lifetime of observing pleasure.
