Utilizing a moderate 50mm objective lens keeps the overall form factor small to make it easier to pack and carry in the field, and their Advanced MultiGuard lens coating system boosts its performance in low and challenging conditions while ensuring the views remain bright and clear. Its broad zoom range allows you to more easily scan the landscape for targets at the low 12x with the ability to quickly dial up the power to 45x and make detailed observations of distant subjects.

The chassis is made of a lightweight and durable aluminum alloy that is protected by a black rubber armor. The chassis is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging even in extreme weather and temperature conditions. The angled-viewing configuration sets the eyepiece at a 45° angle to the scope's body, which places the user's head in a more comfortable viewing position versus straight-through viewing models. A 1/4"-20 mount makes it compatible with many tripods, quick release plates, and other popular support systems like window mounts, and Vanguard includes a compact tabletop tripod to get you observing right out of the box. A lightweight carrying bag makes it easy to carry in the field.

附加信息

通过非常精确地选择主要存在于星云中的氢阿尔法 (H-alpha) 和氧 III (O-III) 的波长，该滤光镜将增加恒星物体与天空背景之间的对比度。因此，使用它可以获得更高质量的图像，包括更清晰的星星和更精细的细节。

<

只保留必要的

双波段滤波器的设计只允许两种特定波长穿过 Vespera 传感器：
– O-III
– H-α

由于经过过滤的波长，它对于拍摄发射星云（例如：猎户座星云 M42、心脏星云 IC 1805……）、富含氢的暗星云（例如：马头星云或象鼻星云……）、行星状星云（例如：猫头鹰星云 M97、哑铃星云 M27……）、超新星遗迹（例如：面纱星云、蟹状星云 M1……）特别有效。

对于球状星团（例如：武仙座星团 M13、星团 M92……），双波段滤光片的选择性将帮助您获得更清晰的星星。

专为 Vespera 研究的过滤器

我们的工程师专门研究了双波段滤光片的光学质量，使其能够在全光圈下使用，而不会对仪器的光学直径产生任何影响。镜头环配备了电子微卡，使 Vespera 能够检测双波段滤光片并调整其观察和图像处理参数。

透射曲线

该滤波器在每个波长上具有 12nm 的带宽（O-III = 500.7nm，H-alpha = 656.3nm）。

附加信息

露水是天文爱好者的一大天敌，在寒冷或潮湿的环境下，望远镜、照相机的镜头上会结露水滴，影响观测和拍摄的质量。

当温度和湿度达到一定阈值时，Vespera 的防露系统就会启动。镜头周围不断产生的热量会消除雾气，从而创造更好的观看条件和更清晰的图像。

它非常适合居住在潮湿地区（海洋、河流、湖泊、池塘等）或温度较低的地区的人。当温度接近 0° 摄氏度时，该传感器在冬季也非常有用。

防露系统

通过为您的工作站配备此传感器，当达到特定温度和湿度阈值时，Vespera 的集成除雾器将启动。镜头周围不断产生的热量将去除露水，从而创造更好的观看条件和更清晰的图像。

提高专注力

产生露水或雾气的凝结会影响 Vespera 光传感器的焦点：

• 初始化和获取时间可能会更长，因为我们的图像处理算法会拒绝大量照片，该算法会检查图像的质量，如果质量不够，则会丢弃它们。
• 在天文摄影中，照片的清晰度主要通过星星的清晰度和是否存在光晕来判断，而照片的清晰度并不好。

湿度计和相关的除雾系统将改善您的观察和照片。

谨慎的设计

该湿度计尺寸小于 13 毫米，配备电子板，这是我们专业工程师设计的最小的电路板。传感器可巧妙地安装到 Vespera 的光学臂中，并可与过滤器配合使用。它会自动打开和关闭防雾系统，因此您无需担心。

安装说明

包装盒内含有：

• 湿度计和准备安装的螺丝，
• 一把迷你螺丝刀。

取下标准 Vespera 镜头环，小心地将湿度计插入镜头上方的凹槽中。使用盒子中提供的螺丝刀将传感器拧紧。传感器不得在其外壳中移动。

要验证传感器是否正确放置，请将 Vespera 连接到您的移动设备并启动 Singularity 应用程序。在空间中心和仪器屏幕上，将显示环境温度和湿度。

使用说明：

• 在安装或移除湿度计之前，请确保 Vespera 已关闭。
• 您无需在每次使用时移除传感器。我们建议将其留在 Vespera 中，以避免任何丢失或损坏。
• 启动除雾系统会导致电池消耗增加。我们建议您在使用前先为除雾站充电。

露水也出现在温度变化较大的情况下，例如在冬天，当您从温暖的环境移到寒冷的环境时，Vespera 内部的空气仍然保持温暖。因此，我们建议您在开始任何观察之前将 Vespera 带到室外至少 30 分钟，以便它能够适应环境温度。

Vespera 光污染滤镜或 CLS（城市光抑制）滤镜可让您在城市或郊区观察时提高照片质量。它可以减弱光污染的影响，从而增加被拍摄天体与背景天空之间的对比度。

宽带滤光片可阻挡主要由城市夜间照明或不良自然光发出的波长，同时允许来自天体的主要波长通过。

Highlights:

• Ideal for visual observation and astrophotography.
• Designed for the amateur astronomer or photographer who wants to view and photograph the moon, planets, and deep sky objects.
• Features FPL53 "super" extra-low dispersion (ED) glass in a fully multicoated apochromatic lens system that corrects for both spherical and chromatic aberrations, astigmatism, and off-axis comas.
• This correction creates a wide flat field of view without distortion and removes the blue-tinted halo effect for true high-contrast color transmission.
• Can accept both 2" and 1.25" eyepieces and accessories for visual use.
• Threads on the drawtube allow direct connection of T-rings and other camera mounts.

A ring spacer placed around the objective lens refines star images beautifully in astrophotography.

In the previous SD81S model, a set of three tiny tin foils are placed around the objective lens as a spacer between the doublet lens. The end of the tin foils protruding over the objective lens obstruct the incoming light. As a result, the protruding tin foils make the light of diffraction of stars chipped radially. Exchanging the tin foils for the spacer ring makes the diffraction of the stars' light equal. It allows you to create more refined and beautiful star images in your astrophotography.

The SD lens suppresses residual chromatic aberration far below the threshold of visibility.

A lens of refracting telescopes has chromatic aberration which is caused by different wavelength of visible light (colors) focusing at different distances. The Vixen SD lenses, made of FPL53 super extra-low dispersion glass, allow for correcting the chromatic aberration over a wide spectrum of light. The SD81SII delivers outstandingly sharp images with high contrast for both visual and photographic applications. Moderately bright F7.7 images will satisfy the most demanding visual astronomer or astrophotographer.

A short optical tube in length is handy for not only visual observation but also astrophotography.

The ED81SII optical tube has a moderate short length to enable you to carry and set it up readily. Also, a lightweight optical tube allows you to balance it with fewer counterweights. The ED81S comes equipped with a metal carry handle and the Vixen standard dovetail slide bar M for quick attaching and detaching. The provided Flip mirror diagonal switches incoming light to allow for using two eyepieces of different magnifications alternately. Also, you can install a camera on the straight side and view an image through an eyepiece on the right-angled side of the flip mirror diagonal.

Full-frame imaging with a DSLR camera.

Using an SD reducer HD kit or an SD Flattener SD kit, which are available optionally, the SD80SII provides an image circle of 44mm, adequate for taking photos with a DSLR camera.

SD Reducer HD Kit: This kit includes a flattener lens to be combined with a reducer lens for a flat and wide imaging field when you use them with the SD81SII, SD103SII, or SD115SII optical tube. The reducer lens reduces a focal length by 0.7X. Direct Wide Photo Adapter 60DX: It is available for Canon EOS or Nikon DSLR cameras. It is possible to change the orientation of a camera for a framing of the photographic field.

Wide Photo Adapter 60DX

High precision camera adapters for prime focus astrophotography are optionally available for Canon EOS and Nikon. The Wide Photo Adapter 60DX is designed to be an integrated camera mount reducing vignetting to the maximum. They are highly effective with full-frame DSLR cameras, and can be used with SD series refractors (in combination with the SD Reducer HD Kit or SD Flattener HD Kit).
