Okular Explore Scientific LER 52° 25 mm 1,25"

Solidly in the mid-magnification range for most amateur telescopes, the 25mm is a true workhorse for visual observers. If you love deep sky observing, eyepieces in this focal length range not only give healthy increases in magnification, but the contrast enhancement of giving a darker background sky can make all the difference of how galaxies and nebulae appear under suburban skies.
