Omegon Ritchey-Chrétien Pro RC 254/2000 Optical Tube Assembly (OTA) - The Astrophotographer's Choice

Elevate your astrophotography to the next level with the Omegon Ritchey-Chrétien Pro RC 254/2000 Optical Tube Assembly. This advanced telescope is designed for photographers seeking stunning, high-quality astronomical images with a wide, coma-free field of view. Discover why RC telescopes are favored by professionals and are now accessible to dedicated amateur astronomers.

Key Features:

• Hyperbolic Mirrors: Delivers extremely sharp images with a wide field of view, eliminating the need for a corrector.
• Quartz Mirrors: Ensures stable focus throughout the night, reducing the need for refocusing during long exposures.
• High Reflection Coating: 92-94% dielectric reflective coating provides bright, high-contrast images.
• Rapid Cool-Down: Open design for quick temperature adaptation. Electric fans for faster cool-down on the 10" model.

Advanced Optics for Superior Imaging

RC telescopes feature hyperbolic main and secondary mirrors, differing from traditional spherical systems like Schmidt-Cassegrain. This innovative design results in sharper astrophotography and a wider usable field of view, making it ideal for APS-C chips without the need for a corrector.

Coma-Free Imaging

Capture pin-sharp stellar images without a corrector using your DSLR or astronomy camera. The 8" and 10" models support 24x36mm full-frame chips, accommodating a wide range of professional DSLR and astronomy cameras. For medium format photography, contact us for tailored solutions.

Precision Focus with Quartz Mirrors

Eliminate focus drift during long exposures with two quartz mirrors that offer minimal thermal expansion. Enjoy consistent, high-quality imaging all night long.

Steel OTA for Stability and High Contrast

The steel optical tube assembly (OTA) reduces focus shift by 50% compared to aluminum OTAs. Strategically placed stray-light baffles enhance image contrast, ensuring excellent astrophotos.

Enhanced Focusing Mechanism

• 3” Linear Crayford Focuser: Supports large format image fields without vignetting.
• Hybrid Design: Combines the ease of a Crayford focuser with the stability of a rack and pinion system.
• Rotatable Focuser: Ensures perfect object alignment.
• Reducer and Compression Ring: Includes a 2” to 1.25” reducer with an integrated compression ring.
• Fine Focus Adjustment: 1:10 reduction for precise focus setting.
• Focus Scale: Quickly return to your last focus setting.
• Stable Alignment: Maintains camera alignment to the optical axis for sharp images.

Superior to Traditional SC Telescopes

Unlike classic SC or Maksutov designs, RC telescopes feature an open system without a corrector plate, adapting rapidly to ambient temperatures and providing brighter images without internal reflections. Ritchey-Chrétien systems are renowned for their edge-to-edge image sharpness, making them the choice for professional observatories.

Accessible Excellence

Once the domain of elite research institutions, RC telescopes are now within reach for experienced amateur astronomers, offering cutting-edge technology at an affordable price.
