Overview
The SVBONY 68-degree 6mm eyepiece is a short focal length option aimed at planetary and lunar observation. At 6mm, it delivers high magnification on your telescope, making it well suited for resolving crater detail on the Moon, the rings of Saturn, and cloud banding on Jupiter. The 68-degree apparent field of view is wider than many budget eyepieces in this class, which helps when tracking planets as they drift across your view.
The 17mm eye relief is a genuine advantage here. Many high-magnification eyepieces in this price range sacrifice eye relief to hit a lower focal length, making them uncomfortable or difficult to use with glasses. This one handles that situation reasonably well.
Fully multi-coated optics and a blackened interior barrel help control internal reflections and improve contrast, which matters at high magnification where any stray light degrades the image. At around $30, this eyepiece competes well for beginners or observers building out a starter kit. Keep in mind that at 6mm you are working at the upper magnification range of most beginner telescopes, so seeing conditions and your scope's aperture will set the real ceiling on what you can resolve.
Key Features
- 68-degree apparent field of view gives more context around planetary targets than standard eyepieces at this focal length
- 6mm focal length delivers high magnification suitable for lunar craters, Saturn's rings, and Jupiter's cloud bands
- 17mm eye relief accommodates observers who wear glasses without removing them
- Fully multi-coated lenses and a blackened interior barrel reduce glare and improve contrast at high power
- Standard 1.25-inch barrel fits most beginner and intermediate telescopes and accepts common filters via M26.5 thread
- All-metal construction with a rubber grip ring adds durability for regular outdoor use

There was a delay in shipping, but once it was shipped was super quick. The eye piece was exactly ams described and very clear, super happy with it. Really feels well made, still fits inside telescope dslr adapter as well.
Great eyepiece. The image is clear. It fits perfectly in a telescope that takes 1 1/4 or has an adapter for one. The eyepiece has a good amount of eye relief and also field of view. I really like this eyepiece.
Really solid eyepieces at a great price. Image is clear and has a nice field of view. The amount of eye relief can be a bit challenging with my glasses.
