Omegon ProNewton N 254/1250 Telescope OTA - Explore the night sky in detail
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.
Top quality optics for clear images
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.
2″ Crayford focuser for precise focusing
The focuser's ball bearing design makes accurate focusing easy. Use 1.25″ or 2″ eyepieces and always find the exact point of focus.
Quickly ready for astrophotography
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.
Rugged metal tube
The all-metal tube guarantees years of observing pleasure. No plastic, but solid material for stable images and long-lasting performance.
Active tubular ventilation
The integrated tubular fan cools the main mirror quickly. So you start observing faster and immediately benefit from optimal image quality.
Easy mounting
The Vixen-style dovetail fits most high-end mounts. Within seconds, the tube is stable and perfectly balanced.
