APO refractors
Apochromatic (APO) refractors use special lenses that offers the best chromatic aberration correction and the highest contrast. Apochromatic refractors are great telescopes for deep-sky astrophotography but can be used with great performances to observe planets, Moon, Sun (with the proper Sun filter) and double stars. Here you find many APO refractors that come with our ESATTO focusers or our SESTO SENSO focusing motors.
