Askar Flattener 1.0x for 185 APO
US$ 348.66The 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.
Askar Reducer 0.8x for 185 APO
US$ 348.66The 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.
Askar Flattener 1.0x for 140 APO
US$ 348.66The 1.0x flattener does not change the focal ratio of the telescope itself. After attaching it to the Askar 140APO, it still maintained a focal ratio of 7. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.
Askar Reducer 0.8x for 140 APO
US$ 348.66The 0.8x reducer can bring the focal ratio of the Askar 140APO 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$ 2,358.43The Askar 140APO is a telescope (OTA) with an aperture of 140 mm, a focal length of 980 mm and a native focal ratio of f/7.
Askar Flattener 1.0x for 120 APO
US$ 235.06The 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 0.8x for 120 APO
US$ 235.06The 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.- New
Askar 120 APO F/7.0 Triplet Refractor
US$ 1,790.45The Askar 120APO's 120mm aperture provides undeniable advantages in light-gathering power, resolution, brightness and contrast, allowing you to capture more light and present more detail and brighter objects in your images. The increased aperture area, which is 36% larger than that of the 103APO, contributes to better performance. 
Askar Flattener 1.0x for 103 APO
US$ 235.06The 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 0.6x for 103 APO
US$ 348.66The 0.6x reducer can bring the focal ratio of the Askar 103APO to F4, also providing field flattening. Askar 103APO adopts a detachable tube design, where the back of the tube can be removed when using the 0.6x reducer, allowing the telescope to have the length needed to achieve an F4 focal ratio.
Askar Reducer 0.8x for 103 APO
US$ 235.06The 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.- New
Askar 103 APO F/6.8 Triplet Refractor
US$ 1,178.78The Askar 103APO is an optical telescope (OTA) with an aperture of 103 mm, a focal length of 700 mm and a native focal ratio of 6.8.
