- 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
- 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
Note: This SV550 80 OTA comes with a dedicated dovetail slot for the finderscope.
The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, it is definitely a great travel telescope for observation and astrophotography.
The triplet apochromatic optics structure (1 piece of S-FPL51 low dispersion ED glass + 2 pieces of correction glass) is adopted to significantly improve the image quality of the captured image (15.8% increase by the spectrometer calculation). Significantly reduces edge dispersion resulting in blue fringing problems.
To remove the 2-inch adapter from the focuser, you will need to loosen the three small screws on the side of the adapter (as indicated in the red circle in the image). Please use an appropriate Allen wrench to gently loosen these screws; there is no need to completely remove them down. Once the three screws are sufficiently loosened, you can turn the adapter counterclockwise to detach it, allowing you to proceed with installing the SV209 flat field lens. Additionally, if you experience any loosening of the focuser adapter during use, you can also adjust the tightness of the small screws to secure it properly.
