Crystal-clear optics for confident observing

The SVBONY SV503 80mm ED refractor brings a color-true, high-contrast view thanks to Extra-low Dispersion glass. The design minimizes chromatic fringing, helping you see subtle stellar hues and fine lunar textures with accuracy.

Every optical surface is carefully coated with ultra-wideband multi-layer coatings. Paired with an 80mm aperture and an f/7 focal ratio, you’ll notice brighter, more even illumination across the field, whether you’re sweeping the Milky Way or spotting distant planets.

Precision you can feel

The dual-speed rack-and-pinion focuser offers a 1:10 gear ratio, letting you dial in critical focus with small, repeatable movements. The result is crisp star points and a steady, tactile focusing experience that supports both visual observation and imaging setups.

  • Dual-speed 2-inch focuser for accurate focus
  • 1:10 gear ratio for fine adjustments
  • Sturdy CNC-machined body with a premium finish
  • Full multi-coated ED optics for brightness and contrast

Versatility for observing and imaging

The SV503 pairs well with SV193 focal reducer, SV705C camera, SV220 and SV226 filters, and SV182 finderscope for a complete imaging or viewing setup. It can also be used with the included 2-inch-to-1.25-inch adapter and dovetail for flexible mounting.

  • Compatible with focal reducers and cameras
  • Filters and finderscope options expand your toolkit
  • Ideal for astronomy beginners and enthusiasts exploring photography

Build quality you can rely on

Crafted with care, the telescope’s body is CNC-machined and finished with a fine-grained coating that feels smooth to the touch. The optical tubes and mounts are designed for longevity and consistent performance under outdoor conditions.

What you get and how it helps you enjoy the night sky

Includes essential components and a robust design that supports longer observing sessions. From the smooth focusing to the reliable optical performance, the SV503 invites you to explore the night sky with confidence.
