SVBONY 10mm 62° Aspheric Eyepiece - 1.25"
The SVBONY 10mm 62° Aspheric Eyepiece delivers a noticeably wider field of view than standard kit eyepieces, fitting any telescope with a 1.25" focuser. Its aspheric design provides a generous 62° apparent field, expanding your view beyond the typical 50° of a Plössl at the same 10mm focal length.
A 62° Aspheric Advantage Over Standard Eyepieces
The aspheric lens design gives sharp images with low chromatic aberration across a wide 62° apparent field of view. All optical surfaces are fully multi-coated to maximize light transmission and contrast.
-
Wide 62° Field: Frames celestial objects with more surrounding sky, making them easier to locate and enjoy in context compared to narrower designs.
-
Fully Multi-Coated: Reduces reflections and improves image brightness, which is crucial for resolving faint details on planets or in dim star clusters.
-
Secure Barrel: The 1.25" barrel includes a recessed safety groove to prevent the eyepiece from accidentally slipping out of the focuser if a thumbscrew loosens.
The 10mm Sweet Spot for Planets and Star Clusters
A 10mm focal length provides medium-to-high magnification, ideal for revealing detail on the Moon and planets. In a common 900mm focal length beginner telescope, this eyepiece yields 90x, enough to see Jupiter's cloud bands, Saturn's rings, and countless lunar craters. The 62° field of view comfortably frames smaller open clusters at this power.

What is the benefit of the SVBONY 10mm Aspheric eyepiece's 62° field of view?
The 62° apparent field of view provides a more immersive, "spacewalk" feeling than standard 50-52° eyepieces. It shows you more of the surrounding sky at the same magnification, which helps in locating objects and appreciating them within their stellar neighborhood.
How will the SVBONY 10mm eyepiece perform on Jupiter with an 8" f/10 Schmidt-Cassegrain telescope?
On an 8" f/10 SCT (2032mm focal length), the SVBONY 10mm eyepiece will provide 203x magnification. This is an excellent power for resolving fine details like Jupiter's main cloud bands, the Great Red Spot, and the shadows of its moons during a transit. The 62° field frames the planet with room to spare, often with its Galilean moons in view.
Is the SVBONY 10mm Aspheric eyepiece a good upgrade from a kit Plössl or Kellner?
Yes. Compared to most standard-issue eyepieces, the SVBONY 10mm Aspheric offers two key improvements: a wider 62° field of view for a more engaging experience and an aspheric design with low chromatic aberration. Its fully multi-coated optics also improve contrast and brightness.
What kinds of deep-sky objects are best for the SVBONY 10mm eyepiece, like the Ring Nebula (M57)?
The 10mm focal length is excellent for smaller, brighter deep-sky objects. It will provide the magnification needed to clearly see the shape of planetary nebulae like the Ring Nebula (M57) or the Dumbbell Nebula (M27). It is also a good power for bright globular clusters like M13 and M92.
Is the SVBONY 10mm Aspheric eyepiece suitable for observers who wear glasses?
Eye relief is not published for this eyepiece, so we cannot confirm how much of the 62° field you will see with glasses on. If you wear glasses only for near- or farsightedness, you can remove them and refocus the telescope.
