A Dobson telescope with an innovative design: the FlexTube

The system FlexTube 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.

Dobson mount: simplicity and efficiency

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.

High-quality optics

The primary mirror parabolic 305 mm, RAQ™ (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.
