Skywatcher Skyliner 250P Flex Tube Synscan GOTO Dobsonian Telescope #10225S (UK)

THE NEW ULTIMATE DOBSONIAN IS BORN!!

Combining the power of a large optical tube, the extreme portability of the patented collapsible FlexTube design and SynScan computerised Go-To technology, the new Skyliner FlexTube Synscan Dobsonians bring over 42,900 celestial objects right in front of your eyes, and automatically track them as they move across the night sky -  its as easy as a walk in the park!

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 no longer feels like watching a kettle boil. Simply push the tube close to the object and let the computer do the rest of the work.

PARABOLIC PRIMARY MIRRORS
Features High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal lengh reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, constrasty images, which are full of detail.

SKY-WATCHER DELUXE MIRROR COATINGS
Most reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope.ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.
