MOUNT AND TRIPOD
EQ5 mount with stainless steel tripod. (upgraded from aluminum tripod)

Standard features of the EQ5 mount include a built-in holder for polar scope, a latitude adjuster with micrometer scale, an azimuth polar-alignment adjuster, aluminum setting circles, large manual slow-motion tracking controls on RA and DEC, and a bubble level. The proposed strong and rigid field tripod is remarkably stable with adjustable height, incorporating 1.5"-diameter steel tripod legs. The lowest possible height with the tripod is 70cm and the maximum extendable height with the tripod is 121cm.

Sky-Watcher  DOBSONIANS

 

 

The Sky-Watcher Dobsonian Telescopes includes 153mm/1200mm (6"), 203mm/1200mm (8") and 254mm/1200mm (10") Newtonian-based models. All models have a "paraboloidal" primary mirror to eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss. In addition, all models include a 2" focuser with a 1.25" adapter, allowing the use of either eyepiece size. The 203mm/1200mm (8") and 254mm/1200mm (10") models also include the new feature-tension control handle.

(203MM/1200MM model shown here).

TENSION CONTROL HANDLE (United States Patent No. 6,940,642)
The secret of the design is to correctly balance the optical tube with special designed handles on the base. The design adds enough friction and tension to allow the tube to move easily when nudged but to stay in position when not. Users can easily add or reduce tension by turning on the handle. This feature solves the common balance problem found on many Dobsonians. Available on all Dobsonian models.

PYREX GLASS ON THE 10"
The Sky-Watcher 10” Dobsonian features a primary mirror made of Pyrex glass. Because of its very low coefficient of thermal expansion, Pyrex glass is less affected by changing temperatures. This greatly reduces the cooling time of a telescope larger than 8” in dameter without using an extra fan. The great stability of this low expansion glass ensures high quality images. It is also substantially more resistant to scratching then plate glass. Available on 254mm/120mm (10") only

153MM/1200MM (6"): Diameter: 153mm focal length: 1200mm, 6x30 finderscope, eyepieces: Super 25mm and Super 10mm. Weight: Tube 6kgs Base 8 kgs.
203MM/1200MM (8")*: Diameter: 203mm focal length: 1200mm, 9x50 finderscope, eyepieces: Super 25mm and Super 10mm. Weight: Tube 8kgs Base 8 kgs.

DOB 8” 10" and 12"  COLLAPSIBLE

 

A COLLAPSIBLE TRUSS-TUBE DOBSONIAN DESIGN THAT REQUIRES NO REASSEMBLY --THE ULTIMATE CONVENIENCE!

SkyWatcher does it again. An old favorite gets a complete facelift with new features and upgraded components!

The venerable Dobsonian reflector design has recently undergone some important upgrades and improvements: SkyWatcher is pleased to introduce the all-new Collapsible Dobsonian complete with Crayford focuser – the ultimate in large aperture portability and performance.

This elegant truss tube design was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the SkyWatcher Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening!

The bearing system has been redesigned as well. The new SkyWatcher Collapsible Dobsonians feature buttery smooth azimuth bearings. Even the twelve-inch model can be rotated with just the push of a finger. Like our traditional Dobsonians, the new Collapsible Dobsonians feature SkyWatcher’s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the telescope.

Introducing the Skywatcher FlexTube Auto-Tracking Fully-Motorised  Dobsonian.

It is the Ultimate in Dobsonian design, the patented collapsible FlexTube(tm) system with a 254mm parabolic primary mirror for ultimate performance & portability, has now been combined with powerful dual-axis servo motors and encoders in the base unit. Now enjoy the luxury of Automatically Slewing and Tracking celestial objects, with the FlexTube's precision diffraction-limited optics with easy handset commands.

Never before has owning a large high quality telescope been so convenient. Now you don't need to worry about constantly repositioning the telescope with the addition of AutoTracking. Objects no longer drift through the eyepiece field of view, leaving you to observe more critically and at your own pace.

The convenience of AutoTracking opens up the possibility of lunar and planetary imaging - without the need for enormous Equatorial mounts or the fuss of polar alignment. The AutoTracking handset allows you to set the local latitude, enhancing the tracking accuracy for astronomical targets.

The controller has 6 different slewing speeds - 32x, 64x and 600x when tracking is turned off and Guide (1x) Slow (4x) and Fast (8x) when tracking is activated.

Because each axis has encoders, the Skywatcher  can still be moved manually over large areas of sky.

Once your target is centred in the eyepiece activate the tracking and you are ready to observe. You still get to enjoy the convenience of Skywatcher's Flex Tube design so the Skywatcher Auto-Tracking Fully-Motorised Dobsonian will fold down to a more compact size for transportation and storage. Skywatcher FlexTube Auto-Tracking Fully-Motorised Dobsonian Features: -

Magnifications (with Eyepieces supplied): x48 & x120 -

Eyepieces Supplied (1.25"): SP10mm & 25mm -

Dual-Fit 1.25"/2" Crayford Focuser -

Parabolic Primary Mirror - 0.5mm Ultra-Thin Secondary Mirror Supports -

9x50 Finderscope -

Direct SLR Camera Connection -
