Omegon Pro RC 250/2000 Telescope - ultimate telescope for astrophotography
Take your astrophotos to the next level with the Omegon Pro RC 250/2000. This Ritchey-Chrétien telescope offers a large, coma-free field of view. Stars remain round and sharp all the way to the edge. Perfect for astrophotography of deep-sky objects and planets.
Sharp and clear image
The hyperbolic main and catch mirrors produce extremely sharp stars. No edge distortion. Your images are ready for processing immediately.
Focus that remains stable
Quartz mirrors are almost impervious to temperature changes. Your focus remains precise, even in long exposures. No more frustrating adjustments during your shooting.
Rapid cooling
The open design allows air to circulate freely and prevents heat fluctuations. Optional fans can be used to make cooling even faster. Less turbulence means brighter and high-contrast images.
Large 3″ focuser for your camera
The 3″ Linear Crayford focuser with ball bearings gives you plenty of room for large sensors without vignetting. Rotatable and with reduction to 2″ or 1.25″. Fine adjustment 1:10 helps you tune the focus perfectly. Your camera stays exactly on the optical axis for razor-sharp results.
Better than SC telescopes
No front corrector plate means no internal reflections. Brighter image and quick adaptation to ambient temperature. RC systems are the best corrected two-mirror telescopes. Sharpness remains impressive at both the center and periphery.
Professional optics, available now
Hyperbolic mirrors were once available only to observatories. Now you can use the same technology as a hobby astronomer.
What we recommend
✓ Moon: excellent - craters and mountains clearly visible
✓ Planets: very detailed - cloud bands and rings sharp
✓ Deep-sky: excellent - nebulae and galaxies sharp to the edge
✓ Astrophotography: perfect - APS-C and fullframe cameras suitable
✗ Sun: not suitable without special filters
✗ Beginners: not recommended
