Omegon Pro RC 304\/2432 Telescope - Truss Carbon for professional astrophotography<\/strong>
Take your astrophotos to the next level with the Omegon Pro RC 304\/2432. This Ritchey-Chr\u00e9tien truss telescope delivers a large, coma-free field of view. Stars remain round and sharp all the way to the edge of the image. Perfect for observatories and advanced amateurs with large-format CCD cameras.<\/p>\n\n\n\n

Hyperbolic mirrors for extreme sharpness<\/strong>
The main and catch mirrors are hyperbolic, not spherical like Schmidt-Cassegrain mirrors. This provides a larger field of view with less distortion. Your stars stay sharp, even at the edges.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Quartz mirrors for stable focus<\/strong>
Quartz mirrors are thermally stable. Focus remains constant even in long exposures. No need for constant adjustment, your photos remain sharp and rich in detail.<\/p>\n\n\n\n

Fast thermal balance<\/strong>
The honeycomb structure of the main mirror and open carbon-truss design allow the telescope to cool quickly. Powerful fans reduce tubus seeding and get your optics ready for razor-sharp shots faster.<\/p>\n\n\n\n

3\u2033 Linear Crayford focuser<\/strong>
The focuser provides ample space for large sensors up to 60 mm. It is fully rotatable, with reduction to 2\u2033 and 1.25\u2033, including 1:10 fine adjustment and scaling. Your camera sits exactly on the optical axis. This prevents tilt and maintains maximum sharpness.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Carbon truss with open gitter design<\/strong>
The system is light, rigid and thermally stable. The open design prevents microclimates inside the tube and provides optimal ventilation. Perfect for long exposures and professional astrophotography.<\/p>\n\n\n\n

Better than an SC telescope<\/strong>
No corrector plate means no internal reflections and brighter images. RC telescopes adjust faster to ambient temperature and deliver superior contrast. Sharpness to the edge is guaranteed.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Deep-sky: large, coma-free image - ideal for galaxies and nebulae
\u2713 Astrophotography: suitable for large CCD and DSLR sensors
\u2713 Moon & Planets: less suitable for large field
\u2717 Sun: not suitable without filters
\u2717 Beginners: not recommended<\/p>\n\n\n\n
