Askar 140APO presentation
Discover the Askar 140APO telescope, a state-of-the-art instrument designed to meet the needs of both amateur and professional astronomers. With an aperture of 140 mm and a focal length of 980 mm, this OTA (Optical Tube Assembly) offers a native focal ratio of f/7, combining light-gathering power, resolution and contrast. Thanks to its triplet APO air-gap lens, including an ED (low dispersion) glass element, the 140APO effectively corrects chromatic aberration, delivering sharp detail and impressive color accuracy.
Accessories for an optimal experience
- Optional accessories :
- Flattener 1x: Maintains f/7 focal ratio while correcting field curvature and coma for finer stars and a flat field.
- Reducer 0.8x: Reduces the focal ratio to f/5.6, widening the field of view and reducing exposure time, ideal for capturing nebulae, star clusters and fast-moving celestial objects.
- These accessories feature integrated 2" filter threads and are supplied with M68/M54/M48 adapters for easy connection.
Precise focus and flexibility
- Rigid 3.5" rack-and-pinion focuser with double speed, equipped with high-precision 10 cm stroke scale.
- The inside of the focuser is designed with an anti-reflective coating to reduce stray light.
- The eyepiece holder incorporates a high-precision 360° rotator, enabling smooth, precise adjustments of rotation angles, secured by a reinforced locking screw.
- Two bases for researchers, positioned on either side of the eyepiece holder, make it easy to change position without dismantling.
Rugged, portable design
- The tube is made of high-quality, precision-machined aluminum with anodized and painted surface treatments, offering an elegant ivory finish accented by orange details.
- Retractable tube design: 735 mm with mist screen retracted and 870 mm with mist screen extended, ensuring optimum portability and manoeuvrability.
- Tube weight: 9.2 kg; total weight (with rings and dovetail): 10.9 kg.
- Rear thread for 2"/1.25" visual adapters, making it easy to add accessories.
