Description
Sky-Watcher 3.2mm Planetary 58° UWA 1.25" Eyepiece
The Sky-Watcher 3.2mm Planetary 58° UWA Eyepiece is a high-power telescope eyepiece designed for detailed observation of the Moon, planets, and close double stars. Its very short 3.2mm focal length provides high magnification, making it a useful addition to a telescope setup when atmospheric conditions allow higher-power observation.
With a 58° apparent field of view and approximately 16mm of eye relief, this eyepiece provides a comfortable viewing experience even at high magnification. The larger apparent field also makes it easier to keep an object within the field of view compared with narrower-field eyepieces.
Designed for High-Magnification Viewing
The 3.2mm focal length is particularly useful when observing fine details on bright astronomical targets. It can provide highly magnified views of the Moon, planets, and close double stars, depending on the telescope and observing conditions.
Because 3.2mm is a very short focal length, this eyepiece is best suited to telescopes that can effectively handle high magnification. Sky-Watcher recommends using the 3.2mm model with telescopes around f/6 or slower.
The optical system uses a modified Plössl design with five lens elements in three groups. The optical surfaces are fully multi-coated (FMC) to improve light transmission and contrast.
