Omegon RC carbon-fibre truss-tube telescope – professional astrophotography for your observatory
\n<\/b>If astrophotography is your passion and you are looking for exactly the right telescope for your observatory, then a Richey-Chretien telescopes 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.<\/p>\n

Now you can use this professional technology for your own observatory too! Omegon RC telescopes are so well-balanced that they can be accommodated in even smaller observatories.<\/p>\n
