## Overview

The Agena 1.25" StarGuider Dual ED Eyepiece - 15mm offers exceptional optical performance with its dual-element ED glass, providing a wide 60-degree field of view. Designed to minimize color aberration and light scatter, this eyepiece delivers sharp, high-contrast images, making it a cost-effective alternative to pricier options.

## Description

Agena's StarGuider Dual ED eyepieces are long eye relief eyepieces with a comfortably wide field for planetary observing that also give the sharpness, high contrast, and lack of lateral color and light scatter of the finest orthoscopic and Plossl designs. These can be used in any astronomical telescope that can accept standard 1.25" eyepieces.Unlike many more expensive eyepieces for planetary observing, the Starguider Dual ED 15mm eyepiece maintains an excellent eye relief of 20mm. With sixlens elements in this unique design, this eyepiece is fully internally baffled and all internal spacers have antireflection microbaffles on their edges with flat black anodizing to reduce reflections when viewing the Moon and bright planets. Every air to glass surface is broadband multi-coated for peak light transmission and outstanding contrast on subtle lunar and planetary detail. Spherical aberration of the exit pupil is well controlled, so there are no serious blackouts or kidney-bean effects if you move your eye slightly off the axis.The eyepiece has a twist-up eyecup that can be raised or lowered to provide the eye relief you find most comfortable. This eyepiece is parfocal with other focal lengths in this series, minimizing the amount of refocusing needed when switching from eyepiece to eyepiece. It is threaded to accept standard 1.25" astronomy filters and weighs approx. 6oz. Note that the color of the trim on the eyepiece may change at any time and may not exactly match the color depicted above.

Review: Great bang for the buck! - Looking for a great eyepiece at a great price? Look no further. I've owned over a dozen different telescopes in the 40 yrs I've been in the hobby of astronomy, and have tried many different brands of eyepieces, too. From the very expensive ones with green lettering to the generic budget offerings, and many in between. With the Starguider, I have found the nearly-perfect combination of quality and price. Flat field across the view, this is a gem. The views are crisp and clear, and the 60° FOV is plenty wide enough for this observer. I selected the 15mm, which gives me 100x in my main scope (a 127 Maksutov-Cassegrain), and based on its performance splitting double star and observing star clusters and nebulae, I will be looking to add additional members of this line to my collection, specifically the 8mm and the 25mm. Bottom line...no need to spend hundreds on a single eyepiece when these are available for $60-$70 each. Perhaps in a 'fast' scope (f/5 or faster) they will show more shortcomings, but for a longer focal length scope such as f/8 or higher, these will definitely do the job, and do it very well.
Review: Best purchase so far for this beginner - Quality eyepiece that wowed even the experienced members of our astronomy club.

### ⭐⭐⭐⭐⭐ A "dark horse" eyepiece deserving of the hightest praise
*by R***S on October 21, 2015*

Greetings, I spent a good amount of time and research looking for a new, high quality set of eyepieces to replace my older sets from the 1980s. I wanted a first-class, "general purpose" eyepiece set that offered a wide field for DSOs (deep sky objects) and high contrast, well-corrected images for planetary and binary star observing. It was a difficult demand to fill at any price. After months researching optics, I had pretty much settled on a lesser known 5-element design by a Dr. Masuyama. Basically, a refined Plössl or symmetrical eyepiece design with a fifth element interposed between the two doublet lenses. Restricting the number of lens elements is highly desirable in keeping light loss and lens scatter to an absolute minimum for planetary observations, while keeping the design at an economical price. Multi-element, wide field oculars (like Naglers) were specifically designed and corrected for fast f/4.5 ratio Dobsonians. But they are large, heavy, dreadfully expensive and optical overkill. That is to say, over-corrected for more moderate f/ratio Newtonians, slow Catadioptrics, well-corrected apochromats and f/8 to f/15 classical achromatic refracting telescopes. While I found the Dr. Masuyama design (Parks Gold oculars) indeed had superb optics for planetary and binary star work, their 52° fields of view were not much of an improvement over my older 42° Vernonscope Brandon and Unitron orthoscopic oculars. I wanted a less constricted view for DSOs in an effort to enjoy a one "general purpose" eyepiece design of exceptional qualities. It was then that I stumbled onto the Agena Dual ED Starguiders. This 5 & 6-element eyepiece immediately impressed me with its first-class fit and finish, weight and design. Its out-of-the-box quality promised good things to come at the eyepiece and it did not fail. Testing the Agena Dual ED 8mm against an 8mm Vernonscope Brandon ($235) and a 7mm Parks Gold ($140) under the severest binary star tests with a Celestron 6" AVX refractor, the Agena proved to be of equal optical performance with the bonus of a much greater 60° apparent field of view. The Agena 60° field is wide enough for impressive deep-sky observations, and imposing lunar landscapes. The optical quality of the Agena meets all of my observational requirements whatever the astronomical target. Globular clusters are well-defined with stars sharply resolved to the core even at 8mm and 6mm. Orion's Nebula displays wispy tendrils and a wonderful, ghostly 3-D appearance, while its Trapezium E and F stars are easily snared. The most delicate binaries are readily detected. Saturnian moons that might, otherwise, be lost in light scatter are easily detected in a black sky. To quote an optician's review of the Agena Dual ED design: "Each Starguider uses two separate ED (Extra-low Dispersion) glass elements of different glass types in its optical system to provide exceptional color fidelity (with vanishingly low levels of chromatic aberration) so that the true color differences between binary star pairs and planetary surface details are easily visible. Their 60° field of view is very flat, particularly with telescopes f/5 and above in focal ratio. They are uniformly sharp edge-to-edge, with markedly low astigmatism. Barrel distortion is essentially non-existent, eliminating the annoying “goldfish bowl” distortion of the image seen in some eyepieces when panning across a star field. Each air-to-glass surface in a Starguider eyepiece is fully multi-coated for high light transmission and exceptional contrast. The high contrast makes them a good choice for splitting close binary stars, for examining low contrast lunar and planetary detail, and for ferreting out small and faint planetary nebulae against a truly dark sky background. The lens edges are blackened to eliminate internal reflections and further improve contrast." As serious observer of 37 years and a hardcore refractor owner, I demand the best in optics. Agena's Starguider Dual ED eyepieces are truly a "dark horse" ocular design that deserves the highest praise. You will NOT regret owning a set of Agena Dual ED eyepieces. This is an outstanding high resolution design at a very affordable price. Steve Franks
