Sky-Watcher Silver Plossl 20mm 52° 1.25″ eyepiece

Looking for a reliable eyepiece that delivers quality images at medium magnification without costing too much? The Sky-Watcher Silver Plossl 20mm eyepiece is a classic choice built on the well-proven 4-element Plossl design - one that has remained popular among astronomers around the world for decades. Whether you are observing the Moon, planets, or exploring deep-sky objects, this eyepiece offers balanced performance and comfortable viewing.

4-element Plossl design - sharp and contrasty views

The eyepiece uses a classic Plossl construction consisting of two symmetrically arranged achromatic doublets. This design provides good correction of optical aberrations and delivers a sharp, high-contrast image across the entire field of view.

The apparent field of view is 52°, which is typical for Plossl eyepieces. It is not the widest view available on the market, but it offers a pleasant balance between the angle of view and sharpness at the edges of the field.

Example magnifications

These are ideal values for observing the Moon in full detail, planetary nebulae, or globular star clusters.

Universal 1.25″ fitting with filter thread

The eyepiece has a standard 1.25″ barrel diameter, which is compatible with the vast majority of amateur telescopes available on the market - refractors, reflectors, and catadioptric systems alike. The filter thread on the barrel makes it easy to attach a lunar or planetary filter without any adapters.

Comfortable viewing - including for eyeglass wearers

The Sky-Watcher Plossl 20mm is particularly well suited for medium and lower magnifications. At this focal length, the eyepiece provides a comfortable exit pupil size and generous eye relief, which is especially appreciated by observers who wear glasses.
