The SVBONY SV136 18mm Wide Angle Eyepiece (1.25″) is a high-performance mid-power eyepiece designed for immersive visual observing. With its generous 72° apparent field of view and carefully optimised optical design, it delivers sharp, contrast-rich views of the Moon, planets, star clusters, and many deep-sky objects.

• 18mm focal length for versatile mid-power observing
• Wide 72° apparent field of view for immersive sky views
• 5-element optical design for sharpness and colour correction
• Fully multi-coated optics to maximise light transmission
• Adjustable rotating eyecup for comfort with or without glasses
• Standard 1.25″ barrel compatible with most telescopes

Sharp, High-Contrast Optical Performance

The SV136 18mm uses a carefully engineered 5-element lens design to minimise chromatic aberration and maintain high contrast. This results in crisp lunar detail, clean planetary edges, and well-defined stars across much of the wide field.

Ideal for Broad-Field & Deep-Sky Observing

The 18mm focal length strikes an excellent balance between magnification and brightness, making this eyepiece well suited to observing the Moon, medium-sized open clusters, nebulae, and rich Milky Way star fields. Its wide apparent field helps keep objects comfortably framed, even on non-motorised mounts.

Comfortable Viewing & Ergonomic Design

A rotating, adjustable eyecup allows the observer to set the ideal eye position, providing a relaxed viewing experience during extended sessions. This design also makes the SV136 suitable for eyeglass wearers, helping maintain access to the full field of view.

Wide 72° Field for Immersive Views

The expansive 72-degree apparent field of view creates an immersive observing experience, particularly effective when scanning star fields or framing large lunar and deep-sky targets.

Standard 1.25″ Compatibility

With its standard 31.7mm (1.25″) barrel, the SV136 18mm is compatible with a wide range of refractors, Schmidt-Cassegrains, Maksutovs, and Dobsonian telescopes, making it a versatile upgrade for many observing setups.
