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.
The Explore Scientific 52° LER mid-range focal length eyepiece is excellent flat-field multi-element ocular that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, this eyepiece offer incredible value in a very nice eyepiece.
These eyepieces are the choice for observers wearing glasses – with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patented EMD-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed – this makes sure you will be able to enjoy these eyepieces for many years to come.
