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.
