Omegon Ritchey-Chretien Pro RC 355/2845 Truss OTA

Omegon Ritchey-Chretien Pro RC 355/2845 carbon-fibre truss-tube telescope

If astrophotography is your passion and you are looking for exactly the right telescope for your observatory, then a Richey-Chretien telescope is ideal. Their large mirror optics produce a nearly perfect image. The two hyperbolic mirrors provide a large, well-illuminated and coma-free image from the compact design. The result - perfect stellar images right out to the edge of the field of view. That is also the reason why countless professional observatories and institutes swear by this system.

Main features

• hyperbolic mirrors - extremely sharp image, large field of view without need of a corrector
• quartz mirrors - for stable focus without the need to refocus, as the image remains sharp
• suitable for large-format CCD cameras - approx. 60mm of illumination
• stiffened carbon-fibre truss tube system
• high reflection - 92-94% dielectric reflective coating for bright, high-contrast observing and astronomy photos
• rapid cool-down thanks to open design
• high-performance electric fans - minimize tube currents and accelerate cool-down of the optics
