The Omegon Advanced X 203\/1200 is a bright 8-inch telescope for those who want to see more: bright nebulae, detailed planetary disks, textured galaxies. Thanks to its large mirror (203 mm), fast f\/5 aperture ratio and parabolic design, this Dobson delivers stunning images - even in locations with some light pollution.<\/p>\n\n\n\n

\n
\n

Cooling fan with battery holder<\/strong>
The telescope is equipped with a quiet fan behind the main mirror. This fan accelerates the cooling of the mirror to the outside temperature, providing faster thermal stabilization<\/strong> and therefore clearer images<\/strong> with less air vibration in the tube. The fan is battery operated via the included holder and can be easily turned on or off.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Accurate 1.25\u2033 focuser<\/strong><\/h3>\n\n\n\n

The robust focuser makes focusing smooth and precise, even at high magnifications. The integrated 6\u00d730 viewfinder helps you quickly find objects in the night sky.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Smart balance system with spring construction<\/strong><\/h3>\n\n\n\n

The spring ensures stable, balanced elevation movement. This keeps the telescope perfectly balanced, even with heavier eyepieces.<\/p>\n\n\n\n
