SVBONY 62° 4mm

The SVBONY 62 degree 4mm eyepiece is designed primarily for high-magnification views of the moon and planets. Paired with a typical beginner refractor or reflector, this eyepiece will push your telescope toward its upper magnification limits, which makes it best suited for steady nights with good seeing conditions. The 62 degree apparent field of view is a real advantage at this focal length, giving you noticeably more sky than a standard Plossl while keeping the image sharp across most of the field.

The fully multi-coated optics handle light transmission reasonably well for the price point, and users report solid contrast when viewing lunar craters, Jupiter's cloud bands, and Saturn's rings. At just under $12, this is a practical way to add a dedicated high-power option to your eyepiece case without significant financial risk. Keep in mind that at 4mm, atmospheric turbulence becomes very apparent, so results will vary considerably from night to night.

The 1.25 inch barrel fits virtually any amateur telescope. The lightweight build at 0.09 pounds makes it easy to travel with. For the price, it punches above its weight for planetary work.
