SVBONY FMC 1.25 inch 68 Degree Ultra Wide Angle Eyepiece Set 6mm 9mm 15mm 20mm Review (2026)

What is in the set

The set bundles four 1.25 inch eyepieces at 6mm, 9mm, 15mm, and 20mm focal lengths, giving a telescope owner a spread from high to low power without shopping for each one separately. Every eyepiece in the set shares a 68 degree apparent field of view, so switching between them for different targets keeps a similarly immersive, wide feel rather than jumping between a narrow low-cost eyepiece and a wide premium one. Eye relief is listed at 17 millimeters across the set, which is workable for most viewers including many eyeglass wearers, though individual comfort varies by focal length and by how close glasses sit to the eye. Internal optical design varies by focal length, ranging from four to six elements across three or four groups depending on the specific eyepiece.

Coatings and build

SVBONY applies fully multi-coated broadband green coatings to the lens elements, which is a standard step up from single-coated budget eyepieces and helps increase light transmission for a brighter, higher-contrast image. The barrels are aluminum, internally blackened to reduce stray light scattering inside the eyepiece, a detail that affects contrast especially on brighter targets like the Moon and planets where stray light can wash out fine detail. Foldable soft rubber eyeguards block ambient light around the eye and add comfort during longer sessions, and each eyepiece accepts standard 1.25 inch filters through a threaded barrel, useful for adding a Moon filter or color filter later. None of this matches the machining or coating quality of premium eyepiece lines, but it is a reasonable feature set for a budget-oriented set sold as four eyepieces together.

How it performs across focal lengths

Wide-field eyepieces generally get more demanding on a telescope's optics as focal length shortens, and that holds true here: the 20mm and 15mm eyepieces in this set are the most forgiving and will look good in a wide range of telescopes, while the 6mm requires more from the telescope's collimation and optical quality to look sharp across the wide field, especially near the edges. Buyers with fast, short focal ratio telescopes should expect more noticeable edge softness or distortion at short focal lengths than someone using a longer focal ratio scope, which is a common tradeoff for wide-angle eyepiece designs generally and not unique to this set. The 68 degree field is genuinely wider and more immersive than typical 50 degree stock eyepieces that ship with many entry-level telescopes, which is the main upgrade this set offers over what a beginner telescope usually includes.

Value compared to buying separately

Buying four eyepieces individually, even at budget prices, typically costs more than this set, and picking a matched, cohesive set removes the guesswork of choosing complementary focal lengths on a first eyepiece upgrade. That said, a buyer who already knows they strongly prefer one or two specific focal lengths, such as a low-power wide-field eyepiece for deep-sky targets and a higher-power planetary eyepiece, may get better individual optical quality per dollar by choosing single eyepieces from a more premium line instead of a four-piece budget set. This set is best understood as a practical, economical way to build out a usable range of magnifications quickly, not as a path to the sharpest possible views at every focal length.

Who should buy it

This eyepiece set fits telescope owners on a budget who want to move beyond a single stock eyepiece and get a useful spread of magnifications with a noticeably wider field of view than typical starter eyepieces. It works well as a first upgrade for beginner and intermediate telescopes with moderate to slow focal ratios, where the wide field looks good without heavy demands on the optics. Owners of fast, short focal ratio telescopes, or anyone chasing the sharpest possible planetary views at high power, will likely be happier stepping up to premium individual eyepieces instead, particularly at the 6mm end of this set. For anyone who wants an affordable, one-purchase way to try wide-field eyepieces across four useful powers, this set is a reasonable starting point.
