Use this APO OTA apochromatic refractor to reveal the wonders of celestial bodies you can observe the Messier catalog targets the common shooting targets M42 M45 the difficulty factor is simple. The triplet apochromatic optics structure 1 piece of S-FPL51 low-dispersion ED glass and 2 pieces of correction glass effectively improves the blue-edge chromatic aberration problem of single-ED structure imaging. The telescope uses an air-spaced triple optical design that virtually eliminates chromatic aberration resulting in bright high-contrast images for exploring galaxies with better graphic clarity. This amazing little scope also includes the use of a 2.5-inch magnesium alloy dual-speed toothed focus mount 110 which reduces vignetting on full-frame cameras and reduces the weight of the support platform. This APO adopts extreme extinction measures there are multiple light barriers inside the focusing seat and the inner wall of the lens barrel and 4 extinction barriers are designed to meet the ultimate pursuit of extinction.
