Omegon Pro RC 406/3250 Telescope - Professional astrophotography at your fingertips
The Omegon Pro RC 406/3250 is a Ritchey-Chrétien telescope designed for advanced astrophotographers and observatories. It delivers a razor-sharp image over a wide field of view, with no distortion or coma. Stars and nebulae remain spot-on all the way to the edge of your image.
Hyperbolic mirrors for maximum sharpness
The quartz main and catch mirrors keep the focus stable even with temperature changes. Adjustment is hardly necessary. Thanks to 92-94%'s reflective coating, you'll see bright, high-contrast images.
Lots of light and large field of view
With a 406 mm main mirror, you catch a lot of light. This allows you to see deep nebulae, galaxies and clusters bright and clear. The RC design delivers sharpness all the way to the edge, without a corrector.
Fast cooling, minimal turbulence
The open carbon gitter tube allows air to flow freely. This avoids creating hot layers of air that blur your image. The built-in fan cools the main mirror up to 50% faster, so you can start shooting faster.
Strong, accurate focuser
The 3″ Crayford focuser with ball bearings accommodates large CCD cameras. It is fully rotatable, accurately adjustable with 1:10 reduction and remains stable. No tilting, no vignetting, just razor sharp images.
Better performance than SC telescopes
Without a corrector plate, there is no internal reflection. The telescope adjusts more quickly to the ambient temperature. RC telescopes are the best corrected two-mirror telescopes. The image remains razor sharp both in the center and at the periphery.
Ideal for advanced hobby astronomers
RC telescopes used to be available only to institutions. Now you can achieve the same results as an advanced amateur with this technology: large CCD cameras, long exposures and bright, high-contrast images.
