Sky-watcher Skyliner-250px Classic Parabolic Dobsonian Telescope by Sky-Watcher

Sky-Watcher Skyliner-250PX Classic Parabolic Dobsonian TelescopeSky-watcher Skyliner-250px Classic Parabolic Dobsonian Telescope
Sky-Watcher Skyliner-250PX Classic 254mm (10″”) f/1200 Parabolic Dobsonian Telescope. These instruments offer an incredible aperture-to-price ratio. Popularized by John Dobson in the late 1970’s, is a very simple but effective method of mounting a Newtonian Reflector. Fast and easy to set up, the Dobsonian mount consists of a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and to use frictional materials, which allow it to move easily when nudged but to stay in position when not. The mount is designed to be driven by hand as opposed to slow motion controls. All Sky-Watcher Dobsonian models feature 0.5mm Ultra-Thin Secondary Mirror Supports to reduce diffraction spikes & light loss, and high quality Paraboloidal primary mirrors to eliminate spherical aberration.

Sky-watcher Skyliner-300p Flextube Parabolic Dobsonian Telescope by Sky-Watcher

Sky-Watcher Skyliner-300P FlexTube Parabolic Dobsonian TelescopeSky-watcher Skyliner-300p Flextube Parabolic Dobsonian Telescope
Sky-Watcher Skyliner-300P FlexTube 305mm (12″”) f/1500 Parabolic Dobsonian Telescope. Sky Watcher patented FlexTube range of truss-tube Dobsonian models all feature collapsible OTA’s, making them incredibly easy to transport and store, offering the ultimate flexibility for owning an otherwise large telescope. They all feature 2-part telescope tubes attached with 3-arm supports. When in use the tube is fully extended and each arm’s axis is clamped to ensure a rigid, perfectly collimated, high-performance optical system. After use, the clamps can be loosened and the tube retracted into a convenient compact size. Owning a large telescope has never been so easy.

Sky-watcher Skyliner-300p Flextube Synscan Go-to Parabolic Dobsonian Telescope by Sky-Watcher

Sky-Watcher Skyliner-300P FlexTube SynScan GO-TO Parabolic Dobsonian TelescopeSky-watcher Skyliner-300p Flextube Synscan Go-to Parabolic Dobsonian Telescope
The Sky-watcher Skyliner-300P FlexTube 305mm (12″”) f/1500 SynScan GO-TO Parabolic Dobsonian Telescope combines the power of a large optical tube, the extreme portability of the patented collapsible FlexTube design and SynScan computerised Go-To technology. The Skyliner FlexTube Synscan brings over 42,900 celestial objects right in front of your eyes, and automatically tracks them as they move across the night sky. The patented dual-encoder design allows you to manually move the telescope anytime and to anywhere you wish – with no need for realignment. Slewing to an object on the opposite side of the night sky is a breeze, simply push the tube close to the object and let the computer do the rest of the work.

Sky-watcher Quattro-250p Parabolic Dual-speed Imaging Newtonian Ota by Sky-Watcher

Sky-Watcher Quattro-250P Parabolic Dual-Speed Imaging Newtonian OTASky-watcher Quattro-250p Parabolic Dual-speed Imaging Newtonian Ota
Sky-Watcher Quattro-250P Parabolic Dual-Speed Imaging Newtonian Optical Tube Assembly. The new Sky-Watcher Quattro series with their fast f/4 focal ratios, have been specially designed for high quality astrophotography with short exposure times. They are of course also fine telescopes for visual observations. Their tube interiors have knife-edge ray traced baffles to ensure no light is lost, and stray light is kept out! Its paraboloidal primary mirror is made of low thermal expansion, fast-cooling Pyrex glass.

Sky-watcher Explorer-200pds (eq5) Parabolic Dual-speed Newtonian Reflector Telescope by Sky-Watcher

Sky-Watcher Explorer-200PDS (EQ5) Parabolic Dual-Speed Newtonian Reflector TelescopeSky-watcher Explorer-200pds (eq5) Parabolic Dual-speed Newtonian Reflector Telescope
Sky-Watcher Explorer 200PDS (EQ5) 200mm (8″”) f/1000 Parabolic Dual-Speed Newtonian Reflector Telescope. The new Sky-Watcher EXPLORER-200PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-200P Black Diamond Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography.Even better performance for astro-photography and visual use can be achieved when used in combination with Sky-Watcher’s Newtonian coma corrector (Product Code 20233).*Note: the Explorer-200PDS has a larger 58mm secondary mirror, for enhanced field illumination, compared to the Explorer-200P which has a 52mm secondary.
