These are simply the best eyepieces made.

Think of all the heavily advertised eyepieces on the market. NONE have all 3 of the important features required to be considered the best. High Contrast and Resolution, Eye Relief and Wide Field of View

All of the "Big Name" eyepieces have one or two features but never all 3. Except PENTAX. You can get the famous brands or the best.

Important Warranty Info.

(Shown in order 3.5mm, 5mm, 10mm, 7mm, 14mm, 30mm, 40mm. 20mm not shown) The series has expanded from seven focal lengths to eight from 3.5 mm to 40 mm. The XW series features a wide apparent angle of view (70 degrees), JIS Class 4 weatherproof construction and a long eye relief (20 mm). We have tested them and the eye lenses are very wide and have a huge "sweetspot", unlike some wide field eyepieces. The new design uses ED Lanthanum glass and the world's best PENTAX-SMC multilayer coatings. The new XW series retains all the popular features of the current XL series, including the fully adjustable eyecups. All XW models feature a 70-degree apparent angle of view, an improvement over the 65 degrees of the XL-series while retaining the outstanding contrast and resolution. Cemented optical elements are coated internally with the innovative partial coating, which offers much higher light transmission capability than conventional outer surface coating, again a Pentax innovation. Thanks to advanced computer simulation technology, internal reflections are drastically reduced to produce brighter, clearer images. Pentax XO eyepieces - High-performance eyepieces are perfect for high-magnification observation and photography of the planets. High-refraction, low-dispersion lanthanum glass elements to provide high-resolution images with minimal aberrations. PENTAX-original SMC full-surface multi-layer lens coating to improve light transmission efficiency. Advanced computer simulation design technology was used to drastically reduce internal reflections producing brighter, clearer images. JIS Class 4 weather proof construction makes these eyepieces more durable
