SkyWatcher 多布森望远镜 8 英寸

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·多布森推广了一种简单、优雅的设计，用于携带牛顿反射镜。多布森式望远镜因其简单性而受到业余天文学家和望远镜制造商的欢迎。它由一个盒子组成，允许望远镜在高度上旋转，以方位角向左和向右旋转。

多布森式望远镜架依靠望远镜架和望远镜之间的平滑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，望远镜将无法保持在正确位置。

Sky-Watcher Dobsonian 8 英寸望远镜配有张力控制手柄（美国专利号 6,940,642），用户可以轻松调节以增加或减少张力，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，望远镜即使在失衡时也能保持其位置。设置正确后，光学管在您需要时会保持静止，但仍可以根据需要平稳移动以跟随目标的运动。当张力调节器完全拧紧时，它会将光学管锁定在适当位置。

与任何多布森望远镜一样，SkyWatcher Dobsonian 8 英寸望远镜比任何其他类型的望远镜都更物有所值。我们经常被问到，“对于狂热的初学者来说，哪种望远镜是最好的？”。当然，答案取决于您计划如何使用望远镜，但 SkyWatcher Dobsonian 8 英寸望远镜将位居榜首！

Saxon 8 英寸 DeepSky （203/1200）多布森望远镜是您开启天文探险之旅的完美伙伴。这款价格实惠的望远镜配有“抛物面”主镜，可消除球面像差，配有四臂副镜支架，配有精细支架（厚度为 0.5 毫米），可减少衍射尖峰和光损失。

这款望远镜的口径为 203 毫米，焦距为 1200 毫米，管径为 8 英寸。这款望远镜配有优质零件和配件 - 特殊的滚珠轴承结构、Crayford 调焦器、目镜和寻星镜都旨在帮助您获得观察体验。组装后，经过一点练习，您很快就能找到并观察月球的岩石表面、太阳系中的行星以及星团、双星、星云和星系等深空物体。

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。

Saxon 5" DeepSky CT Dobsonian Telescope

The saxon 8" DeepSky CT Dobsonian Telescope （203/1200） features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.

This beginner telescope is the retractable twin to the full-tube saxon 8" DeepSky Dobsonian Telescope and comes with the same specs of 203mm aperture and a focal length of 1200mm. Featuring a collapsible truss-tube dobsonian design, the optical tube can be retracted into a shorter length and locked down to ensure secure and easy transportation. This scope also comes with a paraboloidal primary mirror to eliminate spherical aberration allowing you to see wide-field views of the Moon, constellations and deep sky objects such as the Great Orion Nebula.

Assembly of the telescope requires no additional tools. You'll be pleased with how easy it is to use the saxon 8" DeepSky Collapsible Dobsonian Telescope with its Dobsonian mount. Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.

What is a Dobsonian telescope and why the tension control handle?

A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.

The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.

The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.

These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.

By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

The Ultimate Light Gatherers

The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money. His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments.

The Sky-Watcher 10″ Dobsonian is a large aperture Newtonian reflector telescope with f/5 focal ratio, make it ideal for wide field and deep-sky observation. Big aperture means better light gathering power and with this Sky-Watcher Telescope you are able to see prominent deep-sky object such as nebulae, star cluster and many more. It's also an excellent telescope for viewing planets such as Jupiter, Saturn and its rings and more. 

To top it off, the Sky-Watcher Classic 250P Dobsonian is equipped with a 2″ Crayford focuser and focuser locking screw to allow easy use of either eyepiece size.

Tension Control System
The Tension Control System allows you to adjust the friction setting; to increase or reduce the amount of resistance when moving the tube on the wooden mount, so you always have the appropriate resistance. The secret of the design is to correctly balance the optical tube with the specially designed handles (found on the base) and this adds enough friction and tension to allow the tube to move easily when nudged or to stay solidly in position.

With a massive 32-inch primary mirror, the UL32sg delivers 16 times the light grasp of an 8-inch telescope and four times that of a 16-inch, revealing galaxies, nebulae, and fine structure at a level few instruments on Earth can match.

Despite its extraordinary aperture, the UL32sg is engineered to remain as compact and transportable as possible for its class. Fully assembled, the telescope weighs around 150 kg and features a modular, all-metal construction with sectional truss tubes and a folding altitude bearing structure. A real mirror box provides safe protection for the primary mirror during transport and storage.

Light, Strong, Compact and Still Portable

The UL32sg is built using precision-machined aluminium alloy components, extensively modelled with CAD and FEA to optimise structural rigidity while minimising weight. Eight rigid sectional truss tubes ensure excellent stiffness and collimation stability, even at extreme elevations.

While the UL32sg is not a casual backyard instrument, it remains one of the most compact and practical 32-inch class telescopes available, capable of being transported and assembled by a small team for dark-sky expeditions, observatories, and research installations.

Revolutionary Smart Go-To System

The UL32sg is supplied exclusively in a Smart Go-To configuration, built around the state-of-the-art OnStep control system. This advanced platform combines fully motorised Go-To, high-resolution encoders, and a revolutionary plate-solving smart finder for unmatched pointing accuracy.

Using the system is simple: select a target via the smart hand controller or third-party software such as SkySafari or Stellarium, then with a single button press the telescope captures an image, plate-solves its position, and automatically refines its pointing until the target is perfectly centred.

The system supports automated star alignment, automated “Star Shows” such as Messier Marathons, intelligent routing to reduce slewing time by 30–50%, and full EAA live stacking for electronically assisted observing.

Connectivity includes built-in WiFi and Bluetooth, INDI and ASCOM drivers, real-time clock, spiral search, park/unpark, and full sidereal, lunar, and solar tracking rates. Control is available via smart hand controller, desktop software, or mobile apps on Windows, macOS, Linux, iOS, and Android.

Exclusive Sandwich Mirror Technology

The UL32sg uses a lightweight sandwich primary mirror designed to reach thermal equilibrium far faster than traditional solid mirrors. Rapid cooling dramatically reduces mirror seeing and internal turbulence, allowing the telescope to achieve its full optical potential much sooner in real-world conditions.

Unlike thick solid mirrors that may never stabilise during changing temperatures, the sandwich design delivers sharp, stable images without the need for active cooling systems, avoiding vibration and mechanical complexity.

Enhanced Optical Coatings

Both primary and secondary mirrors receive 96% enhanced dielectric coatings with multiple precision-controlled layers. These coatings maximise reflectivity, reduce scatter, and provide excellent chemical and mechanical durability, delivering bright, high-contrast images even at extreme magnifications.

Real Mirror Cell in a Real Mirror Box

The UL32sg features a fully engineered 27-point flotation mirror cell with sling and 90-degree pivoting lateral supports. This system prevents mirror deformation and eliminates astigmatism commonly caused by simpler collimation designs.

The independent three-point rod-end collimation system allows precise adjustment without stressing the mirror edge, maintaining optical integrity under all observing orientations.

Dual-Speed 2" Linear Bearing Crayford Focuser

The UL32sg is fitted with a precision 2-inch dual-speed linear bearing Crayford focuser, capable of handling heavy modern eyepieces and imaging equipment. The fine focus control provides ten times finer adjustment for critical focusing at high power or during EAA use, with approximately 50 mm of travel.
