Bresser EXPLORE SCIENTIFIC 52 LER Eyepiece 15mm Ar

Solidly in the mid-magnification range for most amateur telescopes, the 15mm 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.

Comfort, Quality, Value.  The Explore Scientific 52° LER Series mid-range focal length eyepieces are  excellent flat-field multi-element oculars  that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece.  Expect exceptional quality and value versus a comparably priced Plossl.   

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.
