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。

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。

高品质经纬仪基座
超稳定的多布森底座为 StarSense Explorer 提供了坚固的基础。它具有大直径可变张力高度轴承、特氟隆方位轴承和侧板上的支架,可提供额外的稳定性(与大多数 10 英寸多布森底座不同)。高度轴承提供平稳的上下运动,而集成的高度“制动”系统允许您沿高度轴调整张力,即使有轻微的不平衡也能实现最平稳的运动。望远镜管上的平移旋钮提供符合人体工程学的握柄,因此您可以精确地指向望远镜,而不会将手上的热量引入光学系统。当天体似乎在夜空中漂移时,您只需对望远镜的位置进行微调,就可以轻松跟踪它们。
高品质光学元件带来炫目视觉效果
这款望远镜配有一个 10 英寸的大型牛顿反射光学管,具有足够的聚光能力,可以呈现天体中令人印象深刻的细节,同时还非常便于携带。您可以清晰、明亮地看到木星的四颗伽利略卫星、云带和大红斑、土星环、猎户座星云的气态辉光、礁湖星云的尘埃带以及我们的邻近星系仙女座。与 StarSense Explorer DX 130 AZ 相比,10 英寸多布森望远镜的聚光面积增加了 380% 以上,可以更好地观察暗淡的物体。
所有镜面均采用我们的 XLT 光学涂层,可明显提高对比度和光通量,从而获得更明亮的视野。借助 XLT,您可以在观察月球和行星以及暗淡的星系和星云时辨别出细微的细节。镜子由低膨胀光学玻璃制成,有助于确保在不断变化的环境条件下获得最佳图像。
这款望远镜还配备了高品质的 2 英寸 Crayford 调焦器。Crayford 设计提供精确而流畅的移动,不会发生焦点偏移。它还包括一个 2 英寸到 1.25 英寸的适配器和一个 2 英寸的延长管,因此您可以将几乎任何 1.25 英寸或 2 英寸的望远镜目镜与您的 StarSense Explorer 多布森望远镜一起使用。调焦器还配有一个翼形螺钉,以便您可以锁定最清晰的焦点。
非常适合城市或黑暗天空场所

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 Saxon 10" DeepSky CT Dobsonian Telescope (254/1200) features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.
This telescope is the retractable twin to the full-tube Saxon 10" DeepSky Dobsonian Telescope and comes with the same specs of 254mm aperture and a focal length of 1200mm.

The Saxon 12" DeepSky CT Dobsonian Telescope features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.
This telescope is the retractable twin to the full-tube saxon 12" DeepSky Dobsonian Telescope and comes with the same specs of 305mm aperture and a focal length of 1500mm. 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 12" DeepSky CT 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.
The DeepSky CT Dobsonian Telescopes series comes in three sizes - 8", 10" and 12".
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.

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。

Hubble UL20 – A Lightweight 20" Dobsonian Telescope
The Hubble UL20 is a made-to-order 20-inch Dobsonian telescope designed for observers who want truly extreme aperture without the bulk and weight of traditional large Dobsonians.
With its enormous 20-inch primary mirror, the UL20 gathers over six times more light than an 8-inch telescope, and almost three times the light grasp of a 12-inch, revealing galaxies, nebulae, and fine structure at a level normally reserved for permanent observatory installations.
A Premium, Light, Compact and Portable Design
Despite its size, the UL20 is engineered to remain practical and transportable. The precision-machined all-metal truss construction delivers exceptional rigidity while keeping overall weight to around half that of traditional 20-inch Dobsonians.
The modular truss design allows the telescope to be broken down for transport, while the reinforced mirror box protects the primary mirror during storage and travel. This makes the UL20 a genuine “portable observatory” for dedicated deep-sky observers.
Optical Performance
At the heart of the UL20 is a premium parabolic primary mirror, individually tested and finished to achieve diffraction-limited performance (Strehl 0.95+). The secondary mirror is specified to 1/10 wave or better, ensuring excellent contrast and pinpoint stellar images across the field.
Both mirrors receive 96% enhanced reflective coatings, maximising light throughput while reducing scatter. This results in breathtaking deep-sky views, extremely faint object detection, and exceptional planetary performance even at very high magnifications.
Choose Your Telescope Control
The UL20 can be customised to suit your observing style. You can use it fully manually, or opt for Guided Push-To or Automatic Go-To systems.
Manual Mode
Even without electronics, the UL20 remains a precision Dobsonian with smooth, stable bearings and a well-balanced truss structure. This allows for classic hands-on observing with direct control and intuitive sky navigation.
Guided Push-To Version
The UL20 Guided Push-To version features the SkyHub2 digital setting circle system, providing accurate real-time telescope positioning without motorised tracking. High-resolution 8192 PPR encoders on both axes continuously update your telescope’s position in compatible planetarium software.
-
Fast one-star alignment, with optional two-star alignment for higher accuracy
-
Compatible with SkySafari, Stellarium, Cartes du Ciel, TheSky, and other ASCOM software
-
Works on Windows, macOS, Android, and iOS devices
-
Extremely low power consumption, up to 100 hours from a 15,000 mAh USB power bank
-
WiFi and Bluetooth supported (WiFi only for iOS devices)
Automatic Go-To Version
The UL20 Go-To version adds fully motorised pointing and tracking for a hands-free observing experience. It includes a smart hand controller with a 30,000-object database and supports advanced 1–9 star alignment for high pointing accuracy.
-
Built-in encoders and real-time clock maintain accurate sidereal, lunar, and solar tracking rates
-
Control via WiFi or Bluetooth using SkySafari, Stellarium, or ASCOM/INDI software
-
Compatible with Windows, macOS, Linux, iOS, and Android
-
Adjustable slew and guide speeds, spiral search, and park/unpark functionality
Choosing Your Focal Ratio: f/3.3, f/3.7 or f/4.2
The UL20 is available in three focal ratios, allowing you to balance comfort, optical performance, and field of view.
Why choose f/4.2?
-
Sharper images with almost 50% less coma than f/3.7
-
Smaller central obstruction (3.5" secondary vs 4.0" on f/3.7)
-
Easier to achieve perfect collimation
-
Better suited for high-magnification lunar and planetary observing
-
A coma corrector is helpful but not essential for many users
Why choose f/3.3 or f/3.7?
-
No ladder required at all for f/3.3; only a small step may be needed for f/4.2 near zenith
-
Extremely wide true field of view, especially with f/3.3
-
Ideal for sweeping large nebulae and rich Milky Way fields
All three versions deliver extraordinary performance. A coma corrector is strongly recommended for the UL20 f/3.3, while the f/4.2 prioritises optical cleanliness and ease of use.
Thanks to Hubble’s two-section truss design for f/4.2 (single-section for f/3.3 and f/3.7), all versions remain equally rigid and transportable. Please note that counterweights may be required for balance, depending on configuration, and are not included.

Hubble UL18 – A Lightweight 18" Dobsonian Telescope
The Hubble UL18 is a made-to-order 18-inch Dobsonian telescope, built specifically for serious visual observers who want true observatory-class performance in a portable, transportable design.
With a massive 18-inch primary mirror, the UL18 gathers over five times more light than an 8-inch telescope, and more than twice the light grasp of a 12-inch, unlocking faint galaxies, delicate nebular structure, and extreme planetary detail that simply isn’t possible with smaller apertures.
Light, Strong, and Surprisingly Portable
Each UL18 is custom built to order using precision-machined all-metal components. The truss construction uses eight rigid aluminium truss tubes and a folding altitude bearing structure to provide exceptional stiffness while keeping overall weight under control.
The large mirror box design protects the primary mirror during transport, while the modular layout allows the telescope to be broken down quickly for storage or travel. Fully assembled, the UL18 weighs just ~33 kg, making it one of the most portable 18-inch class Dobsonians available.
Optical Performance
At the heart of the UL18 is a premium parabolic primary mirror, individually tested and finished to achieve diffraction-limited performance (Strehl 0.95+). The secondary mirror is specified to 1/10 wave or better, ensuring excellent contrast and pinpoint stellar images across the field.
Both mirrors receive 96% enhanced reflective coatings, maximising light throughput while reducing scatter. This results in brighter deep-sky views, improved low-contrast detail, and excellent planetary performance even at extreme magnifications.
Choose Your Telescope Control
The UL18 can be customised to suit your observing style. You can use it fully manually, or opt for Guided Push-To or Automatic Go-To systems.
Manual Mode

Hubble UL16 – 16" Lightweight Reflector Telescope
The Hubble UL16 is a made-to-order 16-inch Dobsonian telescope built for serious visual observers who want maximum aperture without sacrificing portability. Combining advanced mirror technology with precision engineering, the UL16 delivers exceptional deep-sky and planetary performance in a surprisingly manageable package.
Optical Performance
At the heart of the UL16 is a full 16-inch parabolic primary mirror featuring Hubble’s exclusive Sandwich Mirror Technology. This lightweight yet rigid design achieves diffraction-limited performance (Strehl 0.95+) while reaching thermal equilibrium up to ten times faster than traditional solid mirrors. Faster cooldown means reduced mirror seeing and sharper, steadier views sooner after setup.
Both primary and secondary mirrors feature 96% enhanced reflective coatings, maximising light throughput and contrast while minimising scatter. The result is brighter galaxies, improved nebular detail, and high-contrast planetary views even at high magnification.
Engineered for Precision
A carefully designed flotation mirror support system combined with independent collimation ensures the primary mirror is evenly supported, minimising astigmatism and maintaining optical accuracy across the sky. The UL16’s robust construction uses CNC-machined aluminium structural components and a steel mirror cell, providing excellent rigidity without unnecessary mass.
Smooth, Accurate Focusing
The UL16 is equipped with a 2-inch dual-speed Crayford focuser featuring linear bearings for smooth, backlash-free operation. Fine focus control allows precise adjustment at high magnifications and works seamlessly with heavy eyepieces or imaging accessories.
Big Aperture, Thoughtful Portability
Despite its impressive aperture, the UL16 is designed with transport in mind. The truss-tube construction breaks down easily for travel, while the fast focal ratios keep eyepiece height within a comfortable range. Whether observing from your backyard or transporting to dark skies, the UL16 balances power with practicality.
Unmatched Observing Potential
With significantly more light-gathering power than a 14-inch telescope, the UL16 reveals faint galaxies, subtle nebular structure, and fine planetary detail that smaller instruments simply cannot match. From resolving globular clusters to tracking delicate dust lanes in distant galaxies, the UL16 is built for observers who want to go deeper.
Push-To and Go-To Options
Guided Push-To Version
The UL16 Guided Push-To version features the SkyHub2 digital setting circle system, providing accurate real-time positioning without motorised tracking. High-resolution (8192 PPR) encoders on both axes continuously update your telescope’s position in compatible planetarium software.
Alignment is quick and intuitive using a one-star or optional two-star alignment. The system works with SkySafari, Stellarium, Cartes du Ciel, TheSky, and other ASCOM-compatible software on Windows, macOS, Android, and iOS devices. Power consumption is extremely low, allowing up to 100 hours of operation from a 15,000 mAh USB power bank. WiFi and Bluetooth are supported (WiFi only for iOS).
Automatic Go-To Version
The UL16 Go-To version adds fully motorised pointing and tracking with a smart hand controller featuring a 30,000-object database. Multi-star alignment (1–9 stars) ensures precise pointing accuracy, while built-in encoders and a real-time clock maintain accurate sidereal, lunar, and solar tracking rates.
Control the system via WiFi or Bluetooth using SkySafari, Stellarium, or ASCOM/INDI-compatible software on Windows, macOS, Linux, iOS, or Android. Adjustable slew and guide speeds, spiral search, and park/unpark functionality provide smooth, precise operation for extended observing sessions.
Choosing Your Focal Ratio: f/5 or f/4.5
The UL16 is available in f/5.0 or f/4.5, allowing you to tailor the telescope to your observing style.
Why choose f/5?
-
Approximately 30% less coma than the f/4.5 version
-
No coma corrector required for most observers
-
Lower cost, saving around $500
-
Smaller central obstruction (2.76" secondary vs 3.1" on f/4.5)
-
Optimised for observers seeking the cleanest possible visual performance
Why choose f/4.5?
-
Lower eyepiece height, no ladder required for most users
-
Wider true field of view, ideal for large nebulae and star fields
-
Slightly more compact overall system
-
Coma is mild and often unnoticed by most observers without a corrector
Both focal ratios deliver outstanding views. The f/5 prioritises ultimate optical cleanliness, while the f/4.5 emphasises comfort and wide-field observing. Thanks to Hubble’s two-section truss design for f/5 (single-section for f/4.5), both versions remain equally portable and rigid.
Please note that counterweights are required for the f/5 configuration and are not included.

Hubble UL14g – 14" Lightweight Reflector Telescope
The Hubble UL14g is a premium 14-inch Dobsonian telescope designed for serious visual observers who want substantial aperture in a system that remains genuinely portable. Combining advanced mirror technology with precision-machined construction, the UL14g delivers impressive deep-sky and planetary performance in a compact, travel-friendly design.
Optical Performance
At the heart of the UL14g is a full 14-inch parabolic primary mirror featuring Hubble’s exclusive Sandwich Mirror Technology. This lightweight yet rigid design achieves diffraction-limited performance (Strehl 0.95+) while reaching thermal equilibrium up to ten times faster than traditional solid mirrors. Faster cooldown means reduced mirror seeing and sharper, more stable views shortly after setup.
Both primary and secondary mirrors feature 96% enhanced reflective coatings, maximising light throughput and contrast while minimising scatter. This results in brighter galaxies, improved nebular structure, and high-contrast planetary detail even at high magnifications.
Engineered for Precision
The UL14g uses a real mirror box and precision flotation mirror support system to evenly distribute load across the primary mirror, minimising deformation and preserving optical accuracy across the sky. The structure is built from CNC-machined aluminium components with a steel mirror cell, providing excellent rigidity while remaining exceptionally lightweight.
Eight rigid truss tubes ensure stable collimation, while the large altitude bearings provide smooth and predictable motion during tracking.
Smooth, Accurate Focusing
The UL14g is equipped with a 2-inch dual-speed Crayford focuser with linear bearings, delivering smooth, backlash-free focusing. Fine focus control makes it easy to achieve critical focus at high power and supports heavy wide-field eyepieces without flex or slippage.
Big Aperture, Exceptional Portability
Despite its 14-inch aperture, the UL14g is remarkably easy to transport and set up. The modular truss-tube design breaks down into compact components that can be assembled in just a few minutes without tools. The heaviest single component is the primary mirror, weighing around 7 kg, making solo transport realistic for most observers.
With its fast f/4.6 focal ratio, the eyepiece height remains accessible at all times — just 60 inches at zenith — allowing comfortable observing with both feet on the ground.
Unmatched Observing Potential
The UL14g collects approximately 36% more light than a 12-inch telescope and nearly double that of a 10-inch, allowing significantly fainter objects and finer details to be resolved. From dense globular clusters to delicate dust lanes in distant galaxies, the UL14g reveals a level of structure that smaller instruments simply cannot match.
From dark-sky sites, most NGC objects are within reach. Bright emission nebulae show subtle hints of colour, planetary nebulae display internal structure, and Jupiter reveals fine banding and atmospheric detail. With an H-beta filter, even challenging targets like the Horsehead Nebula become achievable under good conditions.
The UL14g strikes a rare balance between serious aperture and true portability, making it a telescope that gets used often, not one that stays in storage.

Hubble UL32 – 32" Lightweight Reflector Telescope
The Hubble UL32sg is a flagship 32-inch Dobsonian telescope designed for serious deep-sky observers, research-grade visual work, and advanced EAA applications. 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.

Hubble UL12 – 12" Lightweight Reflector Telescope
Hubble UP12 – An Ultra-Portable 12" Dobsonian Telescope
The Hubble UP12 is a premium 12-inch Dobsonian designed for observers who want serious optical performance in an exceptionally compact and travel-friendly form. Weighing just 14.5 kg) fully assembled, the UP12 delivers true large-aperture performance in a package that can be transported, stored, and deployed with ease.
Once disassembled, the UP12 can be packed into airline-approved luggage, making it one of the most portable 12-inch telescopes available. This is a genuine “take anywhere” instrument for dark-sky trips, remote expeditions, and observers who value performance without bulk.
Light, Compact and Truly Portable
The UP12 is less than half the weight of a traditional 12-inch Dobsonian. Its modular construction allows the entire system to be assembled in just a few minutes, with no heavy components and no complex setup.
All major structural elements are made from precision-machined aluminium alloy, providing excellent rigidity while keeping weight to an absolute minimum. The result is a telescope that feels effortless to transport, yet remains mechanically stable at high magnifications.
Optical Performance
The UP12 uses a premium parabolic primary mirror, individually tested and finished to achieve diffraction-limited performance (Strehl 0.95+). The secondary mirror is specified to 1/10 wave or better, delivering high contrast and sharp stellar images across the field.
Both mirrors receive 96% enhanced reflective coatings, maximising light throughput and reducing scatter. From a dark sky site, the UP12 is capable of revealing most NGC objects, subtle structure in bright nebulae, fine planetary detail on Jupiter and Saturn, and even challenging targets such as the Horsehead Nebula when used with appropriate filters.
A Perfect Balance of Power and Portability
The UP12 gathers around 44% more light than a 10-inch telescope, yet remains dramatically smaller and lighter than traditional 12-inch designs. Its full 12-inch optical surface (with a generous 12.4-inch overall diameter) provides slightly more true light-gathering area than many mass-produced 12-inch mirrors.
This balance makes the UP12 a telescope that actually gets used. It is large enough to deliver meaningful deep-sky performance, yet portable enough to be taken out frequently without hesitation.
