Sky Rover UF 24 mm Ultra Flat Field Eyepiece
Designed for Edge-to-Edge Clarity
The Sky Rover UF 24 mm Ultra Flat Field Eyepiece brings premium optical refinement to wide-field observing. With its true flat-field design, generous 65° apparent field, and comfortable long eye relief, it delivers pinpoint stars and crisp contrast from edge to edge — whether used in a telescope or high-end binocular telescope.
Precision Optics in a Compact Form
This 24 mm eyepiece uses an 8-element, 5-group optical system, fully multi-coated to maximize light transmission and reduce reflections. The design eliminates field curvature and edge distortion, keeping stars sharp across the entire field of view.
With 29 mm of eye relief and a 30.2 mm field stop, the UF 24 mm offers relaxed viewing even for eyeglass wearers. The fold-down rubber eyecup provides comfort and helps block stray light during nighttime observing. A removable top cap reveals a M43 x 0.75 male thread, allowing attachment of filters, smartphone adapters, or other accessories.
Mechanical Design and Practicality
At about 330 grams, the eyepiece feels substantial but remains well balanced on most 1.25" focusers. Its precision-machined aluminum body and dark internal baffling suppress stray reflections, while the flat-field optical layout ensures uniform focus across fast telescopes and binocular systems. The result is a clean, high-contrast image that stays sharp to the very edge of the field — a hallmark of truly refined eyepiece design.
Under the Night Sky
In use, the UF 24 mm delivers an immersive, natural view. Large open clusters fit comfortably in frame, with pinpoint stars from center to edge. Extended nebulae maintain uniform brightness, and subtle dark lanes in the Milky Way become easier to trace. It’s an ideal focal length for low-power sweeping in refractors and binocular telescopes alike — and an outstanding companion to higher-power flat-field eyepieces for a balanced observing set.
Community Insights
Observers who use flat-field eyepieces often comment that once they experience a sharp, distortion-free edge, there’s no going back. The Sky Rover UF 24 mm is frequently praised for its consistency across optical systems — holding tight star images even in fast refractors and binocular telescopes where curvature is most noticeable. Its long eye relief and balanced ergonomics make extended sessions comfortable and fatigue-free.
Observing Tip
If you observe without glasses, keep the rubber eyecup extended to help position your eye precisely at the exit pupil. For eyeglass wearers, fold it down to access the full 29 mm of eye relief. The M43 thread under the top cap is ideal for attaching a camera or filter adapter when using the eyepiece for projection imaging or through a binocular telescope.
Final Thoughts
The Sky Rover UF 24 mm Ultra Flat Field Eyepiece is an elegant combination of optical sophistication and user comfort. Its flat-field design, broad 65° apparent field, and generous eye relief make it equally at home on premium refractors, Maksutovs, or large binocular telescopes. It doesn’t just show you the sky — it shows it with a sense of stillness and clarity that makes observing feel effortless.
