Currently the largest Apochromatic refractor made by Orion. This formidable instrument produces razor-sharp, false colour-free views, highly suitable for astrophotography and observing.
Apochromatic refractors have somewhat of a cult following; they are considered the finest instrument to observe and photograph the skies. Once relegated to a price range affordable by those drowning in money, they have come down to swim in the shallow end.
