The AX103S is a top-of-the-range ED apochromat in the refractor series. It features a triplet ED object lens and a rear-mounted field-flattener lens.
The f8.0 refractor contains a central ED lens in the objective and reduces chromatic aberration to an absolute minimum.
An optional focal reducer can reduce the aperture ratio to 1:5.6 in order to provide quicker results for astrophotographers.
The built-in field flattener lens provides a sharp image across the entire field of view – an essential requirement in astrophotography. The 60 mm ring on the focuser allows you to attach a 2’’ eyepiece or accessories and a camera adapter. The AX103S is specially designed for photography, but also offers stunning visual performance, especially for observing the moon and the planets.
The AX 103S is corrected for full frame photography and provides razor-sharp pictures right into the corners of the image field.
This telescope is guaranteed to provide a lifetime of outstanding performance!
