Sky-Watcher Skyliner 300P FlexTube - Maximum power in a compact package<\/h3>\n

A 305 mm Dobson telescope for demanding observers... on the move!<\/strong>
\nThe Sky-Watcher Skyliner 300P FlexTube features an impressive 305 mm diameter parabolic primary mirror, capable of revealing the finest structures in nebulae, galaxies and planets. Thanks to its ingenious FlexTube<\/strong>Despite its large size, it is easy to transport - ideal for enthusiasts looking for a large diameter without sacrificing practicality.<\/p>\n

NEW :<\/strong> supplied with two wide-angle eyepieces (12.5 mm and 20 mm - 70\u00b0 field of view), a 1.25\u2033 adapter with brass clamping ring to protect your accessories, plus a universal smartphone adapter. Perfect for capturing your finest observations in seconds.<\/p>\n

A Dobson telescope with an innovative design: the FlexTube<\/h3>\n

The system FlexTube<\/strong> allows the optical tube to be retracted in an instant, reducing its length from 144 cm to just 92.5 cm. This unique design simplifies transport, storage and loading in a car. Once extended, a 3-point locking system guarantees rigidity and stability, even during prolonged observation at high magnification.<\/p>\n

Dobson mount: simplicity and efficiency<\/h3>\n

Based on John Dobson's alt-azimuth principle, this stable wooden mount moves the telescope smoothly on two axes without motors or electronics. Manual tracking is intuitive and natural. Assembly is rapid, requiring no complex tools.<\/p>\n

High-quality optics<\/h3>\n

The primary mirror parabolic<\/strong> 305 mm, RAQ\u2122 (Radiant Aluminum Quartz) treated, offers reflectivity of up to 94 % for vivid images. The ultra-thin 0.5 mm secondary support helps limit diffraction and achieve greater image sharpness. Whether you're aiming at the spiral arms of a galaxy or the divisions of Saturn's rings, the Skyliner 300P delivers exceptional clarity.<\/p>\n
