Designed for long eye relief (20mm) and equipped with retractable rubber eyecups, it provides sharp, high-contrast planetary and lunar views. Compatible with standard 1.25" telescope mounts and filters, this lightweight, cost-effective eyepiece is ideal for amateur astronomers seeking premium optical performance without premium prices. ## 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 25mm eyepiece maintains an excellent eye relief of 20mm. With five lens 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: Decent quality - These perform rather well, for being cheap in price. The only issue across the line is the edge distortion that is present. Stars are rather ghastly at the edge, particularly when "walking" through the sky at a slow clip. However, the central image provided is sharp & bright. Review: Great eyepiece - Amateur amateur astronomer, but I upgraded to this and love it, very nice crisp image. ## Features - 1.25" eyepiece; 25mm focal length; 60° Apparent Field of view - Fully multi coated optics; 5 lens elements in 3 groups - Cost-effective alternative to expensive Orthoscopic and Plossl eyepieces - Long eye relief of 20mm - Rubberized body with retractable eyecups for optimum adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00YFZRENC | | Customer Reviews | 4.8 4.8 out of 5 stars (10) | | Date First Available | May 28, 2015 | | Is Discontinued By Manufacturer | No | | Item Weight | 13.1 ounces | | Item model number | 4332012997 | | Manufacturer | Agena AstroProducts | ## Product Details - **Brand:** Agena AstroProducts - **Eye Piece Lens Description:** Plossl - **Finderscope:** Reflex - **Focal Length Description:** 20 millimeters - **Item Weight:** 13.12 ounces - **Lens Coating Description:** Multi-Coated - **Manufacturer:** Agena AstroProducts - **Objective Lens Diameter:** 25 Millimeters ## Images ![Agena 1.25" Starguider Dual ED Eyepiece - 25mm - Image 1](https://m.media-amazon.com/images/I/41bzKtZUBtL.jpg) ![Agena 1.25" Starguider Dual ED Eyepiece - 25mm - Image 2](https://m.media-amazon.com/images/I/41TBPhGmdjL.jpg) ![Agena 1.25" Starguider Dual ED Eyepiece - 25mm - Image 3](https://m.media-amazon.com/images/I/31aSC7ixP-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent quality *by I***N on June 9, 2023* These perform rather well, for being cheap in price. The only issue across the line is the edge distortion that is present. Stars are rather ghastly at the edge, particularly when "walking" through the sky at a slow clip. However, the central image provided is sharp & bright. ### ⭐⭐⭐⭐⭐ Great eyepiece *by J***N on July 14, 2023* Amateur amateur astronomer, but I upgraded to this and love it, very nice crisp image. ### ⭐⭐⭐⭐⭐ Five Stars *by S***R on July 31, 2015* Quite possibly the best series of eyepieces in this price range. Stars are sharp across the field. I've been very involved in amateur astronomy for over 40 years. I've owned 9 different telescopes of all types and quite a number of eyepieces, (I won't even hazard a guess on how many) from inexpensive Erfle's and Kellners to high quality Naglers. In my opinion this series of eyepiece is a top performer and a great value . --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/31690421-agena-1-25-starguider-dual-ed-eyepiece-25mm](https://www.desertcart.com.ar/products/31690421-agena-1-25-starguider-dual-ed-eyepiece-25mm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-03*
