Askar APO Triplet Refractors

The Askar APO triplet refractors are three-element apochromatic refractors with focal ratios around f/7, built for high-resolution imaging and sharp visual views. The range covers the 103APO f/6.8, the 120APO, 140APO and 160APO, and the large 185APO and 203APO f/7.

Each tube has matched accessories in this collection: a 1x field flattener for a flat field at native focal length, and 0.8x reducers (plus a 0.6x for the 103APO) for a faster, wider setup. The 185APO adds a full-frame flattener and reducer.
