Celestron Ultima Edge 24mm 1.25" Eyepiece – Flat Field Precision with Comfortable Eye Relief
If you’re searching for a premium wide-angle eyepiece that delivers sharp, distortion-free views from edge to edge, the Celestron Ultima Edge 24mm 1.25" is an outstanding performer. This eyepiece is part of Celestron’s acclaimed Ultima Edge line, designed with modern optics for today's high-resolution telescopes.
With a generous 24mm focal length and a fully corrected 65° apparent field of view, the Ultima Edge 24mm offers a superb blend of magnification and expansive sky coverage. It's especially well-suited for sweeping views of star fields, large open clusters, and extended nebulae, making it a favorite for both deep-sky and lunar observation.
Fully Corrected Flat Field Optics
At the heart of the Ultima Edge eyepiece is an 8-element, 5-group optical system engineered to produce a flat, true field across the entire view. This design virtually eliminates field curvature and off-axis astigmatism—even at the edges—giving you pinpoint stars across the entire 65° field. Whether you're observing with an f/5 Newtonian or a high-focal-ratio Schmidt-Cassegrain, the performance holds steady.
High-Contrast Multi-Coated Glass for Crisp Views
Every air-to-glass surface is fully multi-coated with Celestron’s advanced broadband coatings. Combined with blackened lens edges and internal baffling, this eyepiece delivers excellent contrast and reduces light scatter. Planetary detail, faint galaxies, and lunar textures all appear with enhanced clarity.
Comfortable Eye Relief and User-Friendly Design
With 29mm of eye relief, the Ultima Edge 24mm is ideal for eyeglass wearers, but it also provides a relaxed viewing experience for anyone who values comfort during extended sessions. The twist-up rubber eyecup lets you fine-tune your eye position, and the rubber grip ring ensures a secure hold, even in dewy or gloved conditions.
Precision Machined 1.25" Barrel with Filter Threads
The anodized aluminum barrel is precision-machined and threaded to accept standard 1.25" filters, so you can easily enhance planetary contrast or reduce skyglow during urban observing. The barrel is also undercut to improve retention in your diagonal or focuser.
A Versatile Performer Across Telescope Types
Whether you’re using a fast Dobsonian, an SCT, or a refractor, the Ultima Edge 24mm adapts seamlessly. Its optical correction and generous field make it an excellent low- to medium-power eyepiece for nearly any setup.
For observers who demand flat field performance, edge-to-edge sharpness, and generous eye relief in a lightweight, ergonomic package, the Celestron Ultima Edge 24mm 1.25" eyepiece is an easy recommendation. It's an ideal upgrade from standard Plössls and a strong contender in the premium mid-power eyepiece category.
