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.

Vixen SD115S 115mm Refractor Telescope - Objective Lens

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.
