Vixen Optics SD103S 103mm FPL-53 ED APO f/8 Refractor Telescope


Introducing the Vixen SD103S 103mm FPL-53 ED Refractor Telescope - a cutting-edge apochromatic refractor featuring advanced Super-ED glass (SD).

Crafted with precision, the FPL53 glass ensures unparalleled image clarity and sharpness by remarkably minimizing residual chromatic distortions.

The distinctive trait of these SD refractors lies in their compact design and lightweight construction.

The SD glass is ingeniously engineered to meticulously converge violet, red, blue, yellow, and green light beams onto a single plane.

This specialized lens material drastically diminishes chromatic aberrations across the entire color spectrum.

When paired with the innovative SD Reducer HD Kit or SD Flattener HD, these refractors facilitate the illumination of a 44mm image circle, accommodating full-format SLR cameras.



  • 103mm Aperture: The 103mm aperture gathers ample light, enhancing brightness and detail, making it perfect for faint celestial objects like galaxies and nebulae, as well as providing sharp planetary views.
  • Super FPL-53 ED Glass Lens: This advanced lens minimizes chromatic aberrations, ensuring that images are sharp, true to color, and exhibit high contrast. This is crucial for accurate astronomical observation and astrophotography.
  • Compact and Lightweight: The telescope's compact design and lightweight build make it easily transportable and quick to set up. This convenience is ideal for astronomers who are frequently on the move.
  • Ideal for Planetary Observation and Photography: Its optical features make it particularly adept at revealing fine details on planets such as Jupiter's cloud bands, Saturn's rings, and Mars' surface. Astrophotographers will appreciate the accuracy and clarity it brings to planetary photography.
  • 44mm Image Circle: When used with accessories like the SD Reducer HD Kit or SD Flattener HD, the telescope can provide a wide 44mm image circle. This is a boon for astrophotographers using full-format SLR cameras, as it eliminates vignetting, ensuring consistent image quality across the frame.
  • Pure-Color, High-Contrast Images: The combination of its optics and design results in images that faithfully represent the colors of celestial objects while providing distinct contrast between features. This greatly enhances the overall visual and photographic experience.
