SVBONY 68° Ultra Wide Angle Eyepiece — 6mm
The SVBONY 68° Ultra Wide Angle Eyepiece in 6mm focal length provides a broad 68-degree apparent field of view, enabling quick target acquisition and easier centering. The design helps you track moving objects with less telescope nudging, enhancing planetary detail. With FMC coating, light transmission improves, producing brighter, clearer images of the Moon’s craters and the rings of Saturn and the planets Jupiter. The internal blackened tube reduces reflections, supporting higher contrast in regions with bright stars.
SVBONY 68° Wide-Angle Eyepiece Family — 6/9/15/20mm Set
This 68-degree set covers multiple focal lengths (6mm, 9mm, 15mm, 20mm), providing a broad field of view for sweeping starfields and rich deep-sky targets. The fully multi-coated lenses and broadband green film optical glass improve light permeability, delivering sharp, high-contrast images with faithful color rendering. The multi-element design maintains good resolution and minimizes aberrations across the field, while the wide apparent field of view makes it easier to locate and track objects without constant refocusing.
SVBONY 72° 34mm Ultra Wide Eyepiece
The 34mm, 72-degree ultra wide angle eyepiece delivers a generous field of view with high contrast and sharpness. Using advanced LOW dispersion and high refractive index optical glasses, combined with durable multi-layer coatings, the eyepiece emphasizes a flat, wide field with excellent edge-to-edge clarity. A removable soft silicone rubber eyecup adds comfort during extended observing sessions, while the design optimizes image quality across the field, making it a solid choice for sweeping star fields and large deep-sky targets.
SVBONY 66° 6mm Ultra Wide Angle Eyepiece
This 66-degree field of view eyepiece emphasizes high magnification with reduced reflections thanks to multiple anti-reflective coatings. A 6mm focal length provides detailed lunar and planetary features, such as surface textures on the Moon and atmospheric bands on gas giants. The blackened interior minimizes stray light, preserving contrast against brighter backgrounds. This is a practical option for observers who want a crisp, high-contrast view at higher magnifications without excessive glare.
SVBONY SV190 Ultra Flat Field Eyepiece — 18mm
The SV190 Ultra Flat Field Eyepiece is designed to minimize field curvature, delivering a uniformly sharp image from center to edge. The 18mm focal length sits in the mid-range for comfortable wide-field viewing, with 65-degree visibility and long eye relief. Fully multi-coated optics reduce reflections, preserving brightness and color fidelity. The blackened lens edges further improve contrast, making it a strong addition for observers exploring star clusters, galaxies, and planetary details across a wide frame.
SVBONY SV154 70° Wide Angle Eyepiece — 15mm
The SV154 offers a 70-degree field of view with a 13mm eye relief for comfort during longer sessions. The 15mm focal length provides a balance between field width and magnification, suitable for broad star fields and detailed views of larger deep-sky targets. A 5-element, 4-group lens structure delivers sharp, high-contrast imagery with good edge-to-edge performance. The twist-up eyecups aid alignment and comfort for eyeglass wearers.
Buying Guide: Key Considerations for Ultra Wide Angle Eyepieces
Choosing the right ultra wide angle eyepiece involves balancing field of view, apparent field, eye relief, and optical design.
- Field of view: Wider fields (68–72° range) help you locate targets and track extended objects like star clusters and nebulae.
- Focal length variety: A set spanning multiple focal lengths offers flexibility for planetary detail (shorter) and deep-sky sweeps (longer).
- Optical coatings: Fully multi-coated optics improve light transmission and reduce reflections, boosting brightness and contrast.
- Eye relief and comfort: Longer eye relief and comfortable eyecups matter for extended sessions, especially if you wear glasses.
- Field flatness and edge sharpness: Flat-field designs reduce distortion toward the edge of the view, yielding crisper stars across the field.
- Build quality: Durable housings with light-scattering blackened interiors help maintain image clarity.
- Compatibility: Ensure the eyepiece fits your telescope’s 1.25″ or 2″ focuser and note any required adapters for optimal seating.
Optical choices often involve trade-offs between magnification, field coverage, and brightness. For planetary work, prioritize high magnification and good edge-to-edge sharpness. For deep-sky observing, a wider field and comfortable eye relief become more critical. A well-rounded kit typically includes several focal lengths to cover both needs, complemented by an astrophotography-friendly Barlow lens or filters if relevant to your setup.
