Askar Reducer 0.8x for 185 APO
US$ 355.54

The 0.8x reducer can lower the focal ratio of the Askar 185APO to F5.6. This is a standard gearbox with field flattening capability. A shorter focal ratio allows the OTA 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.

US$ 355.54

The 1.0x flattener does not change the focal ratio of the telescope itself. After being attached to the Askar 185APO, it maintained a focal ratio of 7. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.
