Product Details
254mm (10") F/1200 Parabolic Truss-Tube Dobsonian Telescope.
Sky-Watcher are proud to introduce a new range of truss-tube dobsonian models. The new FlexTubeTM 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!!

A precision instrument that breaks the stereotypical Dobsonian mold to deliver stunning planetary and deep-sky performance in a compact, readily transportable package."
"The upper section of the FlexTube containing the secondary mirror assembly and Crayford focuser extends with effortless precision on three rods that are easily locked into position at their greatest extent. Despite repeatedly collapsing and extending the instrument in the course of an prolonged observing session, the FlexTube's optics remained in perfect alignment."
"It would be easy to pigeonhole the 305mm FlexTube as an innovative, transportable Dobsonian for the deep-sky enthusiast, but it's much more than that. Its stunning planetary prowess will have many observers redefining what short focal ratio Newtonians are capable of."
"Having used a wide range of Sky-Watcher Newtonians over the years, I've often expressed my pleasure at the the consistency and precision with which the mirrors are polished and figured. In my Astronomy Now review of this instrument's predecessor, the Skyliner-300P, I wrote of its enviable optical performance for the price. I didn't think the 305mm FlexTube would surpass it, but it does."
"Saturn is often described as the jewel of the Solar System, but to see it in all its 24-carat splendour you need a 12-inch FlexTube. In recent memory I haven't seen such a sharp and richly rendered image of the ringed planet as that delivered by the 305mm FlexTube on the night of April 8th, 2008."
"I was able to use the 305mm FlexTube on a wide variety of celestial objects under what passed for fine observing conditions from my heavily light-polluted suburban locale. Messier 3, the stunning globular cluster in Canes Venatici, was resolved into a ball of innumerable stars, some held with direct vision right across the core. Messier 82, the starburst galaxy in Ursa Major, easily revealed mottled dusty filaments across its nucleus. Edge-on galaxy NGC 4565 in Coma Berenices showed the dust lane along its slender form. And so the list went on."
"Mars, just 6.6 arcseconds in diameter, revealed its 90% gibbous phase with ease. But what surprised me was plainly identifying the Syrtis Major near the planet's meridian at such a distance from Earth."
