Saxon 8 英寸 DeepSky 多布森望远镜在组装过程中不需要任何额外的工具，并且使用起来非常简单，是天文学初学者的完美望远镜。

什么是多布森望远镜以及为什么要使用张力控制手柄？

20 世纪 70 年代末，约翰·多布森 (John Dobson) 发明了一种简单而优雅的地平式方位角支架，用于承载牛顿反射镜。多布森式支架望远镜因其结构简单而受到业余天文学家和望远镜制造商的青睐。最简单的多布森式支架由一个盒子组成，该盒子允许光学管组件在高度上旋转，而盒子本身则在底座上以方位角旋转。

多布森式支架通常依靠望远镜光学管上的侧轴承与鞍座上的摩擦材料之间的摩擦力来将光学管固定到位。如果摩擦力太大，望远镜很难移动到视野中心。如果摩擦力太小，望远镜将无法停留在原位。这使得使用多布森式支架时很难稳定望远镜的光学管，尤其是在光学管上添加了寻星镜或目镜等附件时。只要摩擦力大小合适，光学管就能稳定，望远镜就可以保持在所需位置来观察物体，即使在支架旋转时也能保持其位置。

目前可用的稳定多布森式支架上望远镜的装置包括：一个可切片的重物，以平衡望远镜的重量，一个必须调整以抑制望远镜移动的摩擦锁，以及一个连接在望远镜筒和支架之间以辅助稳定的弹簧。

这些装置使用起来很不方便，因为它们没有提供简单且用户友好的方法来调整摩擦力。saxon 张力控制手柄发明的目的是提供一种张力调节器，用户可以轻松转动它来增加或减少张力，从而增加或减少光学管和支架侧板之间的摩擦力。

通过提供这样的张力调节器，望远镜无需保持平衡即可保持在原位。张力调节器可以拧紧，这样光学管就可以保持在原位，但在需要调整光学管的位置时仍然可以移动。或者，张力调节器可以完全拧紧以将光学管锁定在原位。

ZWO FF65 APO 也是您进行目视观察的不错选择。它适合对角线以及各种目镜，可以实现完美对焦，甚至可以用超高倍率目镜观察行星。

望远镜的整体设计紧凑轻巧。OTA 仅重 2 公斤，包括管环和其他配件在内的全套重量为 2.8 公斤。它的光圈为 65 毫米。焦比为 f/6.4，焦距为 416 毫米。与其他 ZWO FF APO 折射镜的四片式结构不同，FF65 APO 是五片式结构，具有两个 ed 玻璃元件，可出色地控制色差和其他像差。

ZWO FF65 APO 支持全画幅成像圈，光点图精细，周边星点畸变小。2.5 英寸刚性调焦器配有新型带刻度的 360° 旋转器和取景器底座。还附带 M68、M54 和 M48 相机适配器，M48 适配器带有 2 英寸内螺纹，可用于安装滤镜。

AP-SM Equatorial mount

The Advanced Polaris (AP) mount is ideal for beginners learning to use an equatorial mount, as well as experienced observers looking for a simple, grab-and-go setup. It securely supports your telescope's optical tube, providing a stable and comfortable observing experience. Thanks to its friction control system, the mount can be quickly and smoothly moved to your target object. A wide range of optional accessories is available to customize the AP mount to suit your observing needs..

R.A. Motor module and STAR BOOK ONE Set

The AP-SM equatorial mount comes equipped with the RA motor module and the STAR BOOK ONE set, which includes the main motor for celestial tracking and the STAR BOOK ONE controller. This set forms the core of the AP mount system. You can customize and expand your setup by adding additional modules to the RA motor module and STAR BOOK ONE base.

Stylish design

The new stylish and compact design helps break the stereotype of astronomical telescopes being bulky and difficult to use. Weighing just 3.6 kg (excluding the counterweight), the mount is lightweight and easy to handle—even with full-scale astronomical telescopes. The power supply, using four AA batteries, is built into the body, and the use of internal electrical contacts eliminates the need for external wiring that was previously exposed.

Friction control system

Simply point the target objects by moving the optical tube by hands. The friction control system allows you to manually point the telescope at the object without using knobs and clamps.

Simple polar alignment

The optional polar meter can be attached on the equatorial mount for simple polar alignment. Even beginners can quickly align polar axis. For precision alignment, the polar axis scope is usually used, but the polar meter can outperforms especially where Polaris is not visible.

Polar alignment scope PF-L

The PF-L polar alignment scope features a three-star alignment system and a built-in dark field illuminator, allowing you to perform polar alignment while looking directly through the scope. The illumination automatically turns off to conserve power.

To complement the PF-L, we provide a free app called "PFL Assist" for smartphones and tablets. This app supports polar alignment by visually indicating the correct star positions within the displayed constellation.

Power supply system focusing on mobility and comfort

The motor module operates with 4 pieces of the AA batteries which are commercially available anywhere easily, not only corresponding to the alkaline battery but also economical rechargeable batteries (Ni-MH, Ni-Cd). For long term use, a commercially available USB external power supply such as USB mobile battery or USB AC adapter can be used connecting to the provided USB Micro-B terminal.

R130Sf Newton reflector

The 130mm aperture newton reflector which is excellent in light gathering power is ideal for observation of faint nebulae and star clusters in a wide and bright field of view.

APP-TL130 tripod

**Special Price on the BINTEL Display Model! One only available**

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. (Photo) M8, M20 nebulae taken with Vixen SD81SII with SD reducer HD kit (compound focus 496mm) and Pentax K-1 at ISO1600, 49 minutes exposure.

Optional accessories to expand your pleasure of taking astrophotography.

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).
