Condition: This is a used Astro-Tech Paradigm 15mm eyepiece in excellent condition. The optics are clean and there is very minimal signs of wear on the barrel. This comes with both end caps as well as the original box. 



This Astro-Tech 15mm Paradigm Dual ED is an excellent medium power eyepiece for lunar observing, encompassing globular clusters, picking up detail in emission and reflection nebulas, etc. This 15mm focal length is a good choice for filling in the gap between the 25/26mm eyepiece that comes standard with most telescopes and a high power planetary/binary star splitting eyepiece. It is usable with any telescope type, under virtually any seeing conditions - from fair to superb. (Rain, snow, or fog might limit its usefulness, however.)

The six lens/four group design and two ED (Extra-low Dispersion) glass elements of the 15mm Astro-Tech Paradigm provides all of the optical virtues described at the top of this catalog page - high contrast, a sharp and flat field from edge to edge, excellent color fidelity, and exceptionally low astigmatism and barrel distortion. It has a long usable eye relief of 15mm. Combined with the twist-up eyecup design, the long eye relief makes it a good choice for eyeglass wearers.
