- The SV550 APO is a compact refractor with 122mm aperture; f/7 focal ratio and 854mm focal length; a great travel telescope for astrophotography and observation; and even some fainter deep sky objects due to the higher limiting magnitude. It weighs 6.44kg/ 14.18lb; easy to carry out and comes with a carrying case bag;
- The SV550 122mm adopts a FPL-51 triplet apochromatic lens structure which contains one piece of ED glass; the triplet lens provides better correction of aberration and greatly reduces chromatic aberration and enhance the clarity and sharpness;
- The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus; the dual speed focuser can provide two focusing speeds by using a set of co-axial knobs; for fast focusing and fine focusing;
- The length of the dovetail is as high as 300mm; it can maintain the balance to the greatest extent; and it will be more convenient in the adjustment process.

- 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 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
