Omegon 114/456 Telescope -. When material and mechanics work together
The Omegon Telescope Pro Astrograph 114/456 is a telescope for advanced astrophotographers. It combines a stable carbon tube with a precision focuser and CNC-machined tube rings. This means: consistent sharpness, stable setup and reliable performance even at long exposures.
Precise focusing
The 2″ Rack & Pinion focuser offers 50 mm of adjustment range. You can bring every detail into sharp focus, even with heavy cameras or long focal lengths. The M56 connector holds your camera firmly in place, with no backlash.
Stable to temperature fluctuations
The carbon tube barely expands at all. This ensures that your focusing position remains constant, even during cold nights. You don't have to make adjustments every time. Perfect for long exposure sequences and automated shooting.
High reflective mirror
The main mirror has a reflectivity of 94%. That means more light output and better detail, even in faint deep-sky objects. Your nebulae and galaxies come into focus more clearly than with standard mirrors.
Maximum stability
The CNC-machined tube rings and prism bar (154/203 mm models) keep your setup rigid. Even with long focal lengths and heavy accessories, everything stays exactly in place. This is crucial for mosaic shots and precision imaging.
Compact and portable
Despite its robust design, the Pro Astrograph is light and compact. The short tube lightens the load on your mount, improves balance and is easy to carry. Perfect for mobile setups or impromptu sessions under clear skies.
Compatibility with focus motors
The focuser works with Omegon Pro Focus Motor Estia, ZWO EAF and iOptron iEAF. No additional adapters required.
What to expect:
✓ Moon & Planets: sharp and detailed
✓ Deep-sky objects: bright and stable
✓ Astrophotography: reliable and precise
✗ Nature observation: not suitable
✗ Sun: only with appropriate filter
