SVBONY SV550 122mm APO Triplet Apochromatic Refractor Telescope Bundle for Astrophotography

The SV550 APO refractor is a compact refractor with a 122mm aperture, f/7 focal ratio, and 854mm focal length, making it a great travel telescope for astrophotography and observation. The OTA (Optical Tube Assembly) weighs 6.44kg/14.18lb, making it easy to carry out when fitting into the carrying case.

The APO refractor features a 122mm aperture, which gathers more light and offers more clear and detailed images, suitable for deep sky photography and observation. It can even capture some fainter deep sky objects due to its higher limiting magnitude.

The SV550 122mm adopts a FPL-51 triplet apochromatic lens structure, which contains one piece of ED (Extra-low Dispersion) glass. This triplet lens provides better correction of aberration and greatly reduces chromatic aberration, enhancing the clarity and sharpness of the images.

The gear ratio of the dual-speed 2.5-inch toothed focuser is 1:10, making it easy to achieve accurate focus. The dual-speed focuser can provide two focusing speeds, using a set of co-axial knobs, for fast focusing and fine focusing.

The 122mm fully multi-coated objective lens and the knife-edge baffle ensure high transmittance while reducing stray light, resulting in a brighter aperture and clear, sharp, and high-contrast images.

The length of the dovetail is as high as 300mm, which is longer than the length of most dovetails on the market. This can maintain the balance to the greatest extent and make the adjustment process more convenient.

The entire tube rings have 26 screw holes, compatible with more equipment installations, such as Smart WIFI devices, guide scopes, and astronomy cameras, meeting various needs of installations.

The 7nm dual-band filter is designed to reduce the effect of light pollution and enhance the contrast, bringing out the detailed information when imaging emission nebulae. This feature allows astronomy enthusiasts to enjoy the fun of deep-sky photography anytime and anywhere in urban areas, even under serious light pollution or a full moon.

In summary, the SV550 APO refractor is a compact, highly capable telescope that offers excellent performance for astrophotography and deep-sky observation, even in challenging light-polluted environments, thanks to its advanced optics and accessories.
