Omegon Plössl 20 mm Eyepiece (1.25 inch): classic four-element lens with sharp image
The Omegon Plössl 20 mm is a classic eyepiece with four lens elements and multicoating. A versatile general-purpose focal length and often the first logical upgrade alongside an included eyepiece.
On a 130/900 Newtonian, a 20 mm gives a magnification of 45x, on a 200/1200 Dobson 60x. The Moon fits completely in the field of view and star fields remain bright.
Features
- Classic Plössl design with four lens elements: sharp to the edge, even on faster telescopes
- Apparent field of view of 50 degrees
- Multicoating for high light transmission and good contrast
- Rubber eyecup against stray light from the side
- Filter thread for moon and color filters (1.25 inch)
Compatibility
Fits any telescope with a 1.25-inch eyepiece holder: Newtonians, Dobsonian, refractors, and Schmidt-Cassegrains. Not suitable for smart telescopes without interchangeable eyepieces.
