SVBONY 23mm 62° Aspheric Eyepiece - 1.25"
The SVBONY 23mm 62° Aspheric Eyepiece delivers a wide 62° apparent field of view in a standard 1.25" barrel, in a light, simple eyepiece. Its 23mm focal length provides low-to-medium magnification, making it an excellent all-purpose eyepiece for scanning star fields and observing large celestial objects.
A 62° Aspheric Field of View
This eyepiece's 62° apparent field of view is noticeably wider than that of a typical Plössl, allowing you to fit more of the night sky into a single frame. The aspheric lens design gives sharp images with low chromatic aberration. All optical surfaces are fully multi-coated to maximize light transmission and image contrast, resulting in brighter views of faint deep-sky objects.
Standard 1.25" Barrel with Secure Fit
Built with a standard 1.25" (31.7mm) barrel, this eyepiece is compatible with virtually any telescope that accepts 1.25" accessories. The barrel includes a recessed anti-loss groove, which provides a more secure connection in the focuser drawtube or diagonal, helping to prevent the eyepiece from accidentally slipping out as you move the telescope.

What types of objects is the SVBONY 23mm 62° Aspheric Eyepiece best for?
The SVBONY 23mm Aspheric Eyepiece is ideal for low-power, wide-field views. It works well on large deep-sky objects like the bright core of the Andromeda Galaxy (M31), the Orion Nebula (M42), and large open star clusters such as the Pleiades (M45). It is also well suited to lunar observing, showing the whole Moon at once in most telescopes.
How will the SVBONY 23mm eyepiece perform in an 8" f/10 Schmidt-Cassegrain telescope?
In a typical 8" f/10 SCT with a 2032mm focal length, the SVBONY 23mm eyepiece will yield approximately 88x magnification. This is an excellent magnification for locating objects and observing medium-sized star clusters and nebulae, taking full advantage of the wide 62° field of view.
What is the advantage of the 62° field of view on the SVBONY 23mm eyepiece?
The 62° apparent field of view is wider than the ~50-52° field of standard Plössl or Kellner eyepieces that often come with telescopes. This wider field makes the view feel more immersive and is more practical for framing large celestial objects without having to move the telescope as much.
What does "aspheric" mean for the SVBONY 23mm eyepiece's view?
An aspheric lens has a non-spherical surface profile that helps correct spherical aberration, which softens focus. In this eyepiece it gives sharp images with low chromatic aberration.
Can I use the SVBONY 23mm Aspheric Eyepiece with eyeglasses?
Eye relief is not published for the SVBONY 23mm Aspheric 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.
