Artesky Super ED Eyepieces: Many eyepieces suffer from blurring and distortion at the edges of the field of view. ED eyepieces counteract this lens error with an ED element, similar to apochromatic refractors. These eyepieces therefore offer high colour purity and a distortion-free image.
The Super ED eyepieces have an apparent field of view of 60°, significantly more than classic Plössl eyepieces. This relatively large field of view counteracts tunnel vision. You feel as if you can freely wander around with your eyes and are not looking through a tube. This also ensures fatigue-free observation. You can simply keep your eyes relaxed in the eyepiece for longer.
All glass/air surfaces are multi-coated to prevent unwanted reflections and increase transparency.
