Askar Reducer 0.8x for 103 APO
US$ 237.51The 0.8x reducer can bring the focal ratio of the Askar 103APO to F5.4. This is a standard reducer with field flattening capabilities. A shorter focal ratio allows the telescope to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.Askar Flattener 1.0x for 103 APO
US$ 237.51The 1x flattener does not change the focal ratio of the telescope. After being attached to the Askar 103APO, it still maintained a focal length of f/6.8. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.Askar Reducer 0.8x for 120 APO
US$ 237.51The 0.8x reducer can bring the focal ratio of the Askar 120APO to F5.6. This is a standard gearbox with field flattening capability. A shorter focal ratio allows the telescope to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters and faint, fast-moving celestial objects.Askar Flattener 1.0x for 120 APO
US$ 237.51The 1.0x flattener does not change the focal ratio of the telescope. After attaching it to the Askar 120APO, it maintained a focal ratio of 7. The reducer corrects field curvature and coma, resulting in flatter field edges and sharper star points.Askar Reducer f/3.9 for Refractor FRA400
US$ 299.31FullFrame f/3.9 reducer for Askar FRA400 - Allows you to reduce the Askar FRA400 to f/3.9 with a flattened field for FullFrame - Diagonal equal to 44mm. Integrated 2" thread - M48x0.75 connection. Backfocus 55mm
