SVBONY SV550 Telescope, 80ED F6 Triplet Apochromatic Refractor OTA, 2.5" Micro-Reduction Rap Focuser, 87mm Back Focus Distance, Telescope for Adults High Powered, for Deep Sky Astrophotography&Visual

SVBONY

$574.59

More Details
Main highlights
- 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
- This 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
- 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
