Artesky Super ED Eyepieces: For many eyepieces blurs and distortions appear at the edges of the field of view. ED eyepieces counteract this lens aberration by an ED element, similar to apochromatic refractors. These eyepieces thus provide high color purity and a distortion-free image.
The Super ED eyepieces have an apparent field of view of 60 ° , much more than the classic Plössl eyepieces. This relatively large field of view counteracts the tunnel view. One has the feeling of being able to roam freely with the eye and not to look through a tube. This also ensures a fatigue-free observation. You simply keep your eyes relaxed longer in the eyepiece.
All glass / air surfaces are multi- coated to prevent unwanted reflections and increase transparency.
