The Vixen SD115SII is a new 115mm apochromatic refractor with high-performance Super-ED glass. The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material, reduces chromatic aberration across all colours.
The new Vixen SD115SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. It offers thrilling views of the moon or the brighter planets in pin sharp detail as well as with extremely high contrast. Deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed in very impressive detail under dark skies.
In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44mm image circle for full format SLR cameras.
The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included diagonal mirror allows comfortable observation even in difficult observation positions and additionally offers a T2 thread for connecting a DSLR camera. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope.
