Artesky Super ED 5mm 60° 1.25″ Eyepiece
Most eyepieces lose sharpness and accuracy towards the edges of the field of view. The Artesky Super ED series solves this by adding an ED element to the optical design - the same principle used in apochromatic refractor telescopes. The result is outstanding colour purity and a distortion-free image across the entire field of view, not just at the centre.
The 60-degree apparent field of view goes well beyond what a classic Plössl eyepiece offers. There is no uncomfortable "looking through a tube" sensation - your eyes can move freely across the image, and you can take in the view naturally and without strain. Longer observing sessions become much more comfortable as a result.
All glass and air surfaces carry fully multi-coated optics, which minimises unwanted reflections and maximises light transmission. The twist-up eye cup adjusts by rotation to suit both observers who wear glasses and those who do not. The eyepiece also accepts standard 1.25″ filters via the built-in filter thread.

Who is this eyepiece for?
The Artesky Super ED 5mm suits observers who want more than a basic eyepiece can offer. Whether you are studying the Moon and planets or scanning star clusters, the ED element and wide field of view deliver a noticeably better experience. It works well with both refractors and reflector telescopes.
Comfort for longer sessions
The 60-degree field of view removes the sensation of peering through a narrow tube. Combined with the adjustable twist-up eye cup, this eyepiece lets you observe for longer without eye strain - an important advantage during a full night of observing.
ED glass - what does it mean?
ED stands for Extra-low Dispersion. This type of glass reduces chromatic aberration - the coloured fringing that appears around bright objects in lower-quality eyepieces. The result is a cleaner, crisper image with accurate colours across the whole field.
