- FullFrame 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
- Askar's FMA180 PRO is a triplet APO refractor with double ED glass for excellent correction. The high-quality lenses produce a high-contrast, pure color image and meet the highest demands in astrophotography and observation.
Askar FRA500 90mm f/5.6 Refractor
€ 2,399.00The best seller of the quintuplet series, the FRA500 90mm; It is an instrument suitable for astrophotography.
Thanks to the quintuplet spaced in the air, it provides a flattened field up to 44mm diagonally without the addition of further flatteners/reducers.
Askar FRA300 60mm f/5.0 Refractor
€ 1,299.00The best seller of the quintuplet series, the FRA300 60mm; It is an instrument suitable for astrophotography.
Thanks to the quintuplet spaced in the air, it provides a flattened field up to 40mm diagonally without the addition of further flatteners/reducers.
Askar Reducer 0.8x for 103 APO
€ 269.00The 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 Reducer 0.6x for 103 APO
€ 399.00The 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 Flattener 1.0x for 103 APO
€ 269.00The 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 120 APO F/7.0 Triplet Refractor
€ 2,049.00The 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 Reducer 0.8x for 120 APO
€ 269.00The 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 Reducer 0.8x for 140 APO
€ 399.00The 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.Askar Reducer 0.8x for 185 APO
€ 399.00The 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 185 APO
€ 399.00The 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.
