Vixen Apochromatic refractor AP 103/795 SD103S OTA (56273)

The Vixen SD103S is part of Vixen’s new range of apochromatic refractors featuring super-ED (SD) glass. The redesigned lens uses FPL-53 glass, which greatly reduces chromatic aberration and delivers exceptionally clear and sharp images. When combined with the optional SD Reducer HD or SD Flattener HD kits, these refractors provide a 44mm image circle, making them suitable for full-frame DSLR cameras. The internal baffles are optimized for the M8.

These SD apochromatic refractors are excellent for astrophotography and also provide impressive visual observation. The practical flip mirror allows you to connect an eyepiece at a comfortable viewing angle while also attaching a camera. The telescopes are compact and lightweight, making them easy to handle and transport.

Please note: The product may differ slightly from the illustration. Eyepieces are not included.
