Artesky Super ED 60° 25mm 1.25″ Eyepiece
Overview
The Artesky Super ED 25mm is a premium astronomical eyepiece designed for both beginner and experienced astronomers who demand high optical performance, observing comfort, and reliable build quality. This eyepiece combines modern ED optics with thoughtful ergonomics, delivering exceptional visual experiences when observing planets, the Moon, nebulae, and star clusters. It is engineered to meet the expectations of even the most demanding users while remaining compatible with the vast majority of telescopes available on the market.
ED Optics - Superior Chromatic Correction
The eyepiece features Extra-Low Dispersion (ED) lens elements that effectively eliminate chromatic aberration - a common issue with lower-cost eyepieces that causes colored fringing around high-contrast objects. Thanks to glass with exceptionally low dispersion, the image is sharp and color-accurate across the entire field of view - from center to edge. The result is a natural and comfortable viewing experience free of disturbing optical artifacts, even when used with fast telescopes with a low focal ratio.
Optical Design
The six-element optical system arranged in four groups provides excellent aberration correction and high image contrast. All optical surfaces feature full multi-coatings (fully multi-coated), which minimize unwanted reflections and maximize light transmission. The result is a bright, high-contrast image with faithful rendering of fine details even on demanding deep-sky objects with low surface brightness.
Eye Relief and Eyecup Comfort
A generous 16mm eye relief allows comfortable viewing even for eyeglass wearers, who do not need to remove their corrective lenses to see the entire field of view. The eyepiece is equipped with an adjustable soft rubber twist-up eyecup that extends and retracts smoothly and easily, adapting to the individual needs of the observer. This makes it possible to use the telescope during long observing sessions without eye fatigue and with maximum comfort.
Field of View and Compatibility
The 60° apparent field of view provides a pleasantly wide and well-organized image, ideal for sweeping the night sky, locating deep-sky objects, and observing extended nebulae and star clusters. The 1.25″ barrel diameter is the standard size compatible with the vast majority of astronomical telescopes. The barrel features a standard 1.25″ filter thread, allowing the use of various astronomical filters without additional adapters.
Who Is This Eyepiece For?
The Artesky Super ED 25mm is an excellent choice for astronomers looking for a reliable, comfortable, and optically advanced eyepiece at a reasonable price. The combination of ED optics, full multi-coating, and ergonomic design makes it a versatile tool for visual astronomy - whether you observe from a light-polluted city or a dark rural location. This eyepiece performs equally well as a wide-field overview eyepiece for sky orientation and for detailed study of specific objects. The Artesky Super ED is a premium astronomical eyepiece that surpasses many products in higher price categories in terms of performance and comfort, and will become a reliable companion on every stargazing session.
