With a comfortable 16.5mm eye relief and a user-friendly design, this eyepiece is perfect for both novice and seasoned astronomers looking to enhance their celestial observations. ## 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 8mm eyepiece maintains an excellent eye relief of 16.5mm. 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. ## Features - 1.25" eyepiece; 8mm 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 - Comfortable eye relief of 16.5mm - Rubberized body with retractable eyecups for optimum adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00YFZIGG6 | | Additional Features | Reduced reflections for lunar and planetary viewing, unique 5-element design | | Best Sellers Rank | #438 in Telescope Eyepieces | | Brand | Agena AstroProducts | | Coating | Multi-Coated | | Compatible Devices | Telescope | | Customer Reviews | 4.5 4.5 out of 5 stars (19) | | Eye Piece Lens Description | Plossl | | Field Of View | 60 degrees | | Finderscope | Reflex | | Focal Length Description | 8 millimeters | | Focus Type | Manual Focus | | Item Weight | 6 ounces | | Manufacturer | Agena AstroProducts | | Manufacturer Part Number | SGED-8 | | Model Name | Starguider Dual ED | | Number of Items | 1 | | Number of Packs | 1 | | Power Source | Manual Operation | | Unit Count | 1 Count | ## Product Details - **Brand:** Agena AstroProducts - **Compatible Devices:** Telescope - **Eye Piece Lens Description:** Plossl - **Finderscope:** Reflex - **Focal Length Description:** 8 millimeters - **Focus Type:** Manual Focus - **Item Weight:** 6 ounces - **Lens Coating Description:** Multi-Coated - **Model Name:** Starguider Dual ED - **Power Source:** Manual Operation ## Images ![Agena 1.25" Starguider Dual ED Eyepiece - 8mm - Image 1](https://m.media-amazon.com/images/I/51ZdKW1ajTL.jpg) ## Frequently Bought Together - Agena 1.25" Starguider Dual ED Eyepiece - 8mm - SVBONY Telescope Filter 1.25 inches UHC Filter Astrophotography to Improve The Image Contrast Reduces Light Pollution (1.25 inch) - SVBONY Universal Dovetail Base, Finderscope Mount Bracket, for Installation of Finder Scope for Optical Telescope --- ## 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.sg/products/26114924-agena-1-25-starguider-dual-ed-eyepiece-8mm](https://www.desertcart.sg/products/26114924-agena-1-25-starguider-dual-ed-eyepiece-8mm) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-19*
