Product Info

Manufacturer Description

ED stands for "Extra-Low Dispersion". These eyepieces use optical glass in which two of the lens elements are crafted from ED glass which is a special grade of glass that provides much superior refractive properties as compared to standard optical glass. This results in much better color correction. ED glass is often the type used in many expensive camera lenses and high-end refractor telescopes costing thousands of dollars.

Our ED-series eyepieces are available in a 1.25" barrel in 10 focal lengths (2.3, 3.8, 5.2, 7.5, 9.5, 12.5, 14, 18, 21 and 25mm). They feature a six-element lens design that provides significantly reduced chromatic aberration, high resolution and excellent sharpness without compromising image brightness. Their long 20mm eye relief means that even eyeglass wearers can take in the full 55-degree apparent wide field of view (AFOV).

All ED-series eyepieces are fully broadband multi-coated for maximum image brightness. Lens edges are blackened throughout for improved contrast. The eyepiece housing is precision machined from aluminum and clear-anodized to a lustrous finish. A rubber traction ring ensures a secure grip and a rubber eyeguard helps position your eye to block out stray light. The chrome barrel features a setscrew recess for added security. All eyepieces are parfocal and are threaded to accept standard 1.25" filters. Each eyepiece comes in a bolt case with two plastic end caps. Compare these with the ED eyepieces sold in very similar focal lengths by two of the "Big-3" telescope companies and you'll realize the savings we offer.

      Comments:

      Eyepiece quality / price is great. This 9.5 mm eyepice is really what I expected. It is a bit big, but what you want, if you need light, you need aperture, you need diameter! Great use on my LX 90 8".

      Bottom Line: Would you recommend this item? Yes

      Comments:

      I am not going to into any long review here, but I can honestly tell you that this is one of my favorite eyepieces. This eyepiece is very sharp, very well built, no false color, edge to edge is very good, and has very good eye relief. The Tak FS-102 and the Celestron 9.25XLT were the scopes used at f/10 and f/8.6. So for my scopes this eyepiece was very solid; the name of the game folks is clean sharp views. Yes the FOV is 50 deg. or so but for the price, and the eye relief and performance of this eyepiece, why go spend hundreds of dollars for something you really don't need, IMHO.
