SVBONY SV503 Astronomical Telescope 102mm F7 ED Extra Low Dispersion Refractor OTA for Astrophotography

SV503 Astronomical Telescope 102mm F7 ED Refractor OTA

  • ED Glass structure: The doublet air-spaced achromatic design with S-FPL51 ED glass reduces chromatic aberration, delivering crisp, accurate color images;
  • Large aperture for bright images: The 102mm objective lens with an f/7 focal ratio brings more lights into the scope body and you will get more bright and clear image;
  • FMC-coating for crisp image: Ultra-wideband multi-layer coatings and a retractable lens hood provide bright, wide-field images with sharp resolution, perfect for various types of observation;
  • Dual-speed rack focuser: The 90mm back focus and dual-speed rack and pinion focuser with focus knob cover make it easy to achieve fine, accurate focus for both visual and photography.

Product description

The SVBONY SV503 102 mm F7 ED telescope impresses with its versatility and solid craftsmanship. With an aperture of 102 mm and a focal length of 714 mm, it offers a well-balanced combination of light-gathering power, resolution, and portability.

For visual observation, this telescope performs excellently: the Moon, planets, star clusters, as well as brighter nebulae and galaxies, can be observed with crisp and high-contrast detail. Compared to smaller telescopes, the larger aperture delivers noticeably more light and sharpness, revealing finer structures in celestial objects.

The astrophotography potential of the SV503 is equally convincing. The high-quality ED optics minimize chromatic aberration and produce accurate, color-faithful images. Its sturdy dual-speed focuser allows for precise focusing, which is particularly useful when working with APS-C or smaller camera sensors.

Another advantage is portability: with a length of about 630 mm and a weight of approximately 5.5 kg, the optical tube is easy to transport, making it ideal for mobile setups or travel — perfect for observers who value flexibility.

Among the telescope’s key strengths is its excellent price-performance ratio. Users praise the solid optical quality and robust construction at a very reasonable price. The ED glass correction ensures clean, high-contrast images without the distracting color fringes often found in standard achromatic refractors. The mechanical build quality is also impressive: the focuser operates smoothly and precisely, and the optical tube feels well-made and sturdy. Additionally, the comprehensive accessory package — including tube rings, an adapter, and a Vixen-style dovetail plate — makes setup quick and convenient.

Overall, the SVBONY SV503 102 mm F7 ED refractor offers an excellent all-around package for dedicated amateur astronomers who appreciate high optical performance, reliability, and outstanding value for money.
