探索科学 82° 系列 30mm 防水目镜
描述
“我最近刚刚购买了我的第一台 E.S. 望远镜，因为我拥有了几个很棒的 E.S.目镜。 我有 6.7 毫米和 30 毫米 82° 目镜，它们是我广角和高功率的首选。 它们非常适合我的新 E.D.127mm 折射镜。” - 格雷格·麦凯
30mm 82° 系列防水氩气净化目镜是中上倍放大倍率级别的流行焦距，提供超宽视场和宽大的眼距。 它非常适合任何需要更大功率的应用，包括观察球状星团、行星状星云、彗核附近的明亮云结构、行星的初步观测，以及（在望远镜上进行适当的安全过滤），对活跃的观测太阳的区域。 与 Explore Scientific Focal Extender 一起使用可实现 2X、3X 或 5X 放大倍率，同时保持目镜原生视场和眼距。
采用先进的计算机设计、低色散和高折射率光学玻璃的组合以及耐用的增强型多层沉积 (EMD) 涂层，Explore Scientific 82° 系列超广角目镜经过优化，可产生高对比度、高分辨率和卓越的平场特性. 这些目镜具有较长的眼距和 82° 视场，其视觉效果确实是一种完全沉浸式的体验。 您的眼睛很放松，让您可以轻松地使用“转移视觉”技术来研究巨大视野中的微弱细节。
每个目镜都经过精心组装到精密加工的金属镜筒中，可保持光学系统的完美对准，以便在野外使用多年。 为了将内部反射降至最低，目镜筒的所有内表面以及镜片本身的边缘都是黑色的，以尽量减少镜片本身内的光散射。
探索超宽目镜 - 舒适、品质、价值。 探索 Scientific 82° 系列目镜，其 82° 视场，让您沉浸在一个非常舒适的超宽视野中，自然地促进目镜放松。 当您放松眼睛并进入眼前呈现的场景时，更容易观察更长的时间，并且您可能乍一看可能看不到的细节开始显现。 超宽目镜的另一个巨大好处是您可以轻松地凝视，而不是直接凝视物体，而是稍微向两侧凝视。 这种称为使用转移视觉的技能在观察微弱物体时特别有用，因为使用转移视觉会将图像放在对光更敏感的眼睛部分，让您看到更微弱的图像。
与 探索 Scientific 2X 焦距扩展器（2.0 英寸外径） 将该目镜的放大倍率加倍（使其成为有效的 15 毫米焦距，同时保持相同的眼距和视场。

Customers praised this waterproof eyepiece for its "high quality" and "excellent view." The 82° wide field delivers "pinpoint stars" and "sharp" images across most of the field. Shoppers noted "spectacular views" with "fine, wispy details" on deep sky objects and "excellent light throughput." Heavy at 2 pounds, but well-built.
- Great wide views, completely flat field, stars were pinpoint, can really feel the 82 degrees.
- The views are spectacular with pinpoint stars and an amazing depth of field.
- Excellent light throughput and contrast, fine wispy details clearly seen in emission nebulae.
Great eyepiece - very wide apparent field of view, with decent eye relief. Excellent light throughput and contrast on deep sky objects with fine, wispy details clearly seen in emission nebulae. Used with an 18" f/4.5, stars are sharp across 90% of the field. Typical wide field eyepiece performance in a fast Newtonian scope. The addition of a coma corrector brings all star images to sharp points across the entire field, for those who are perfectionists. In terms of build quality and visual performance, this eyepiece compares very favorably with much more expensive competing units at a much lower price point. Highly recommended!
High quality eyepieces. Have not been able to use yet, but I am excited!
Very nice.
High quality. Excellent view.
Great wide views, completely flat field from what I could see in my single use, stars were pinpoint, and can really feel the 82 degrees. Would highly recommend. This eyepiece was the last of my collection and I'm happy it has filled it.
I needed a wide field low power eyepiece to go with my Askar 140 and what a great match it is! The views are spectacular with pinpoint stars and an amazing depth of field. At 2 pounds it’s a heavy eyepiece but I didn’t have any balancing issues with the OTA on my EQ6-R Pro.
Amazing views with this eyepiece!
Always wanted a wide-angle 30 mm eyepiece, and this one is a beauty. Superb engineering and such a quality product, eager for clear nights with this stunning eyepiece.
Great eyepice
Great clarity. It made finding Neptune and Uranus easy.
Very effective eyepiece, well packed and fast shipping. Can't beat that!
