Bresser Messier Dobson 12" NT-305/1525 is a professional observation set especially recommended for more experienced astronomy enthusiasts. In addition to the optical tube and mounting, the set includes a 1.25" SuperP-lössl eyepiece and a solar filter with housing on the tube inlet, which means that the telescope is ready for use straight out of the box.

Bresser Messier Dobson 12" NT-305/1525 is a classic Newtonian reflector with an aperture of 305 mm and light intensity f/5. The optics of this telescope are made with the highest precision, thanks to which it will allow you to enjoy very sharp views, contrast and practically imperceptible chromatic aberration. The main mirror of this optical tube is made of H-PZ33 glass with a reduced thermal expansion coefficient, making the telescope less sensitive to changes in ambient temperature.

The set includes a stable, yet extremely simple and intuitive Dobson-type mount. Mounts of this type are an ideal solution not only for beginners who love astronomical observations, but are also a basic tool used in photographing aircraft at cruising altitudes (RNAV spotting).
