SVBONY SV550 APO Triplet Refractor 80mm F6 OTA with 2.5 inches Micro-Reduction Rap Focuser Astronomy Telescope Adults for Deep Sky Astrophotography and Visual
- Use this APO OTA apochromatic refractor to reveal the wonders of celestial bodies.
- you can observe the Messier catalog targets.
- 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.
- 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 (1:10).
- 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.
