E-Plössl eyepieces:E than simple. E for one better. These eyepieces are offered as an alternative to the popular Barium eyepieces.
The four-member lens replacement system promises better image quality than Bárium telescopes - especially in brighter telescopes - at a barely higher price. A 1.25" filter thread and rubber eyecups, as well as anti-reflection coatings on all surfaces, are standard features of these eyepieces. Their field of view is about 50°, except the 40 mm which is about 43°.
