Omegon ProNewton N 254\/1250 Telescope OTA -<\/strong> Explore the night sky in detail<\/strong>
The Omegon ProNewton N 254\/1250 opens up a world of brightness and contrast. See moon craters sharply, planetary details down to the smallest cloud bands, and deep-sky objects as if you were looking through a higher-end telescope. Perfect for both visual observation and astrophotography.<\/p>\n\n\n\n

Top quality optics for clear images<\/strong>
The BK7 glass main mirror with 94% reflectance provides maximum brightness and contrast. Faint galaxies and nebulae become visible. Thin spin sticks keep the mirror stable so you see every detail sharply.<\/p>\n\n\n\n

2\u2033 Crayford focuser for precise focusing<\/strong>
The focuser's ball bearing design makes accurate focusing easy. Use 1.25\u2033 or 2\u2033 eyepieces and always find the exact point of focus.<\/p>\n\n\n\n

Quickly ready for astrophotography<\/strong>
The large back focus allows you to easily connect a DSLR or other camera. Take bright, detailed photos of planets, nebulae and galaxies without compromise.<\/p>\n\n\n\n

Rugged metal tube<\/strong>
The all-metal tube guarantees years of observing pleasure. No plastic, but solid material for stable images and long-lasting performance.<\/p>\n\n\n\n

Active tubular ventilation<\/strong>
The integrated tubular fan cools the main mirror quickly. So you start observing faster and immediately benefit from optimal image quality.<\/p>\n\n\n\n

Easy mounting<\/strong>
The Vixen-style dovetail fits most high-end mounts. Within seconds, the tube is stable and perfectly balanced.<\/p>\n\n\n\n
