Vixen Optics SD115S 115mm ED APO f/7.7 Refractor Telescope


Introducing the Vixen SD115S 115mm Refractor Telescope, a cutting-edge apochromatic refractor that incorporates high-performance Super ED glass (SD).

This remarkable telescope utilizes FPL53 glass to deliver exceptionally clear and sharp images by effectively eliminating any residual chromatic aberration.

One standout feature of these SD refractors lies in their compact design and lightweight construction.

The SD glass is ingeniously engineered to converge violet, red, blue, yellow, and green light beams precisely onto the same focal plane, thereby drastically reducing chromatic aberration across the entire spectrum.

To further enhance your astronomical experience, consider pairing these refractors with the optional SD Reducer HD Kit or SD Flattener HD, which expand the field of view to a generous 44mm image circle, perfect for full-frame SLR cameras.

Originally conceived with visual observers and APS-C camera enthusiasts in mind, the ED81SII, ED103S, and ED115S refractors have undergone a transformation in the new SD series.

They now feature optimized inner panels tailored for full-frame cameras.

Equipped with a robust focuser capable of accommodating heavy cameras without causing any tilting of the telescope, this instrument also boasts a foldable mirror, ideal for observations in challenging conditions.

Additionally, it incorporates a T2 thread for seamless connection to a DSLR camera, enhancing its versatility for astrophotography enthusiasts.



  • High-Quality SD Refractor with 115mm Aperture: The 115mm aperture allows this telescope to capture a substantial amount of light, making it an excellent choice for observing celestial objects with great detail. Larger apertures provide better resolution and allow you to see fainter objects in the night sky.
  • Bright, Pure-Color, and Extremely Sharp Image: The use of high-quality Super ED (SD) glass and the elimination of chromatic aberration result in images that are exceptionally clear, sharp, and free from color fringing. This means you can enjoy stunning views of astronomical objects with lifelike colors and intricate details.
  • Also Suitable for Full-Frame Cameras: The telescope's compatibility with full-frame cameras makes it an excellent choice for astrophotographers looking to capture wide-field images of the night sky. You can attach your DSLR camera and take advantage of the telescope's optics to capture breathtaking deep-sky objects and wide-field vistas.
  • Portable and Lightweight, Despite Large Aperture: The telescope's lightweight and compact design make it easy to transport and set up at different observation sites. This portability allows you to take advantage of dark-sky locations and explore various celestial objects without being tied to a fixed observatory.
  • Very High Contrast Thanks to SD Glass: The use of SD glass enhances contrast in your observations. This is particularly advantageous when observing objects like the moon and planets, as it allows you to see finer details on their surfaces and distinguish subtle variations in brightness and color.
  • Ideal for Observing the Moon and Planets: The combination of the telescope's aperture, high contrast, and sharp optics makes it particularly well-suited for lunar and planetary observations. You'll be able to explore the Moon's craters and features in exquisite detail, and observe the planets in our solar system with clarity and precision.
