Eyepieces

What sets the 6mm Ethos-SX 2"/1.25" Eyepiece apart is its exceptional performance and innovative design, a testament to the high standards set by its predecessors, the renowned 13mm and 8mm models. Crafted by the reputable brand, Tele Vue, this eyepiece is a fusion of durability, versatility, and reliability, making it an indispensable tool for any astronomy enthusiast.The 6mm Ethos-SX Eyepiece boasts a wide-angle view, a feature that revolutionizes your stargazing experience by offering a broader field of view. This allows you to observe a larger portion of the sky, enhancing your ability to locate and observe celestial objects. Whether you're gazing at the moon, planets, or deep sky

The 10mm Ethos delivers: 100 Degree apparent field (50% larger in area than 82 Degree Naglers), comfortable eye-relief, (accepts DIOPTRX eyesight astigmatism correctors), distortion correction, high contrast and on-axis sharpness for planetary viewing. It is the "do-it-all" eyepiece perfect for all scopes that can utilize this focal length. And, "filling the hole" between the 13mm and 8mm makes it the ideal centerpiece for a 17mm/10mm/6mm Ethos set. An important benefit of the combination of large apparent field of view and shorter focal length is that for a given field in the sky, higher magnification results in a darker sky background. Fainter stars become visible and more detail is seen

It has now been 20 years since Tele Vue designed the original 13mm Nagler eyepiece. From then on Tele Vue has always sought ways to obtain the largest possible true fields (i.e. longer focal length) while maintaining the basic Nagler concept; 82 degree apparent field with good correction to the edge. The previous Nagler versions were not conducive to scaling to longer focal lengths. A totally innovative design using four different exotic glass types (some larger than the 70mm Pronto objective!) in a 6 element configuration, opened the door to the largest true field possible in the Nagler eyepiece family. With fewer elements, Tele Vue also retained the high contrast achieved on the Radians
