Ritchey-Chretien

Ritchey-Chretien telescopes use a special optical design with 2 hyperbolic mirrors to eliminate off-axis optical errors without the need for corrector lenses: this is why these are the perfect instruments for deep-sky astrophotography and research. Here you find many Ritchey-Chretien telescopes that come with our ESATTO focusers or our SESTO SENSO focusing motors.
