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.
PARABOLIC PRIMARY MIRRORS
All Sky-Watcher Dobsonian Reflectors feature High Quality Parabolic Primary Mirrors to eliminate spherical aberrations. The mirrors are parabolized to bring all the light rays to the same focal point to produce sharp, contrasty images, which are full of detail.
"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."
