Omegon Ritchey-Chretien Pro RC 406/3250 Truss Tube Telescope - Professional Astrophotography Telescope for Observatories

Are you passionate about astrophotography and in search of the perfect telescope for your observatory? The Omegon Ritchey-Chretien Pro RC 406/3250 Truss Tube Telescope is designed just for you. This powerful telescope features large mirror optics that deliver nearly perfect and coma-free images, making it the ideal choice for capturing stunning celestial images.

Key Features:

• Hyperbolic Mirrors: Achieve extremely sharp images across a large field of view without the need for a corrector.
• Quartz Mirrors: Maintain stable focus without refocusing due to minimal thermal expansion.
• Large-format CCD Compatibility: Approximately 60mm of illumination, perfect for professional astrophotography.
• Carbon-Fibre Truss Tube System: Lightweight, stiff, and thermally stable design prevents focus drift.
• High Reflection Coating: 92-94% dielectric reflective coating for bright, high-contrast images.
• Rapid Cool-Down: Open design with high-performance electric fans minimizes tube currents, accelerating optical cool-down.

Superior Image Quality

The RC design incorporates hyperbolic main and secondary mirrors, providing a wider image field with fewer aberrations compared to spherical mirror systems. This makes it an excellent choice for astrophotographers using large CCD cameras, ensuring sharp images right to the edge of the field of view.

Extended Spectral Range

With no lenses in the beam path, RC telescopes eliminate refraction issues like chromatic aberration, offering a broader spectral range that includes UV and infrared light. Capture more detail in your astrophotography with this advanced feature.

Quartz Main Mirror

Say goodbye to focus drift during long exposures. The telescope's dual quartz mirrors ensure stable focus throughout the night by minimizing thermal expansion.

Efficient Cooling System

The 12V fan built into the main mirror reduces cool-down time by 50%, allowing the telescope to reach optimal image quality faster.

Advanced Truss-Tube Design

The carbon-fibre truss-tube design provides stiffness and thermal stability, enhancing natural ventilation and preventing microclimates.

Precision Focusing with 3” Focuser

The 3” Linear Crayford Focuser offers ample space for large-format imaging without vignetting and features:

• Rotatable focuser for perfect object alignment
• 1:10 fine adjustment for precise focus settings
• Setting scale for quick focus recovery
• Stability ensures perfect camera alignment

Easy Alignment

Align the 3" focuser precisely with six collimating screws for optimal image quality and stability, maintaining the optical axis alignment.

Why Choose RC Over SC?

The open design of the RC telescope adapts quickly to ambient temperatures and provides brighter images without internal reflections, setting it apart from classic Schmidt-Cassegrain or Maksutov telescopes.

Accessible Professional Technology

Once reserved for international research institutions, the advanced technology of hyperbolic mirrors is now affordable for experienced amateur astronomers.
