Sky-Watcher Skyliner-250PX FlexTube

254mm (10") f/1200 Parabolic Truss-Tube Dobsonian Telescope

 

These instruments offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the late 1970’s, is a very simple but effective method of mounting a Newtonian Reflector, based on the alt-azimuth principle. 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.
Tube material: Aluminium.

Sky-Watcher Dobsonians feature a unique patented Tensioner/Carrying handle. By lifting the handles together, you can easily carry the whole unit in an upright position with the help of a friend.

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 are proud to introduce a new range of truss-tube dobsonian models. The new FlexTube Dobsonians all feature retactable OTA’s, making them 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 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!!

The SKYLINER 250PX models feature Paraboloidal primary mirrors made of Low Thermal Expansion Pyrex Glass resulting in substantially shorter cooling times.
