2. 安全訊息
WARNING: Do not look directly into the sun with this eyepiece or any telescope, as this can cause severe and permanent eye damage.
Always ensure proper handling of optical equipment to prevent damage to the device and injury to yourself.
3.主要特點
- Wide Observation Field: 一個 66 度的視野 view allows for expansive views of the night sky, suitable for medium-sized star clusters, nebulae, and deep-sky targets, as well as large-scale lunar observations.
- 9毫米焦距： Provides high magnification, ideal for detailed observations of lunar craters, planetary features like Saturn's rings, and resolving double stars.
- 6 Elements in 4 Groups: Multiple lens groups enhance optical performance, delivering clear images with good color correction and contrast.
- 全多層鍍膜（FMC）光學元件： Green film coatings reduce reflection and refraction, significantly improving light transmission for brighter images.
- Reduced Stray Light Design: Blackened lens edges and an internally blackened eyepiece barrel minimize internal reflections, ensuring a crisp and clear image.
- 1.25" Eyepiece Barrel: Compatible with standard 1.25-inch telescopes and accessories such as Barlow lenses and mirror diagonals.
- 篩選器線程： Includes an internal filter thread to accommodate 1.25-inch astronomical filters.
4. 設定與安裝
- 拆箱： Carefully remove the eyepiece from its packaging. Ensure all protective caps are removed from both ends of the eyepiece.
- Inserting into Telescope: Loosen the thumbscrew on your telescope's focuser or diagonal. Gently insert the 1.25-inch barrel of the SVBONY eyepiece into the focuser or diagonal.
- Securing the Eyepiece: Tighten the thumbscrew on the focuser or diagonal until the eyepiece is securely held in place. Do not overtighten.
- 安裝濾芯（選購）： If using an astronomical filter, carefully screw the filter into the threaded end of the eyepiece barrel before inserting the eyepiece into the focuser.

5. 操作說明
- 聚焦： Once the eyepiece is installed, point your telescope at a celestial object. Slowly adjust the focuser knob on your telescope until the image appears sharp and clear.
- 觀察： The 9mm focal length provides higher magnification, making it suitable for detailed views of the Moon and planets. The 66-degree ultra-wide angle offers an immersive viewing experience, allowing you to observe larger portions of the sky, including star clusters and nebulae.
- 眼睛緩解： Position your eye comfortably close to the eyepiece lens. Adjust your distance slightly to find the optimal eye relief for a full, clear field of view.

6. 保養與維護
- 清潔鏡頭： Use a soft, lint-free cloth specifically designed for optical lenses. For stubborn smudges, use a small amount of optical cleaning fluid applied to the cloth, not directly to the lens. Avoid touching the lens surfaces with your fingers.
- 除塵： Use a blower brush or compressed air (designed for optics) to remove dust particles before wiping.
- 貯存： When not in use, always place the protective caps on both ends of the eyepiece. Store the eyepiece in a clean, dry environment, preferably in its original case or a padded container, to protect it from dust, moisture, and impacts.
- 避免極端溫度： Do not expose the eyepiece to extreme temperatures or rapid temperature changes, as this can affect the optical coatings and internal components.

7。 故障排除
| 問題 | 可能的原因 | 解決方案 |
|---|---|---|
| 影像模糊或失焦。 | Incorrect focuser adjustment. | Adjust the telescope's focuser slowly until the image is sharp. |
| 田野中可見的黑點或灰塵 view. | Dust on the eyepiece lens or telescope optics. | Use a blower brush to gently remove dust from the eyepiece lenses. If the dust persists, it may be on the telescope's primary optics. |
| Reduced brightness or contrast. | Eyepiece lenses are dirty or smudged. | Clean the eyepiece lenses carefully as described in the Maintenance section. |
| Vignetting or partial field of view. | Eye not positioned correctly or eyepiece not fully inserted. | Ensure your eye is centered and at the correct distance from the eyepiece. Check that the eyepiece is fully inserted and secured in the focuser. |
