Omegon Plössl 40mm Eyepiece (1.25 inch): Classic four-element design with sharp image
The Omegon Plössl 40mm is a classic eyepiece with four lens elements and multicoating. The longest focal length in the series, for the lowest magnification and the brightest image.
On a Schmidt-Cassegrain with a 2000mm focal length, a 40mm eyepiece provides 50x magnification: this eyepiece is perfectly suited for such long telescopes. Note: the actual field of view with the 40mm is no larger than with the 32mm eyepiece, as the 1.25-inch barrel limits the field edge. You primarily gain brightness and viewing comfort.
Features
- Classic Plössl design with four lens elements: sharp to the edge, even on faster telescopes
- Apparent field of view of approximately 45 degrees (limited by the 1.25 inch barrel)
- 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.
