Omegon Dobson Telescope Advanced X N 304\/1500 is a powerful 12-inch Dobson designed for serious observers. With an aperture of 304 mm and a focal length of 1500 mm, you get an instrument that shows deep-sky objects as they are meant to be seen: bright, contrasty and with a level of detail that smaller telescopes simply do not achieve.<\/p>\n\n\n\n
