The Askar 203APO 203 mm f/7 triplet APO tube is a high-quality optical instrument designed for astronomy enthusiasts and experts. It is a true observatory telescope, with few larger apochromats available to amateur astronomers. Its sophisticated design and manufacturing ensure that the telescope delivers uncompromising performance for both astrophotography and visual observation.
The 203 mm diameter triplet objective with ED lens element minimizes chromatic aberration at a focal length of 1421 mm. The tube features a 3.5" dual-speed rack and pinion focuser, ensuring precise focusing. An important feature is its 360-degree rotatability, allowing easy adjustment in any position.
The tube's design is particularly noteworthy due to the two finder scope shoes and the multifunctional handle, which allow for convenient and secure use. The reinforced tube rings provide extra stability, which is essential for extended observations.
Thanks to its modular construction, the tube is well-suited for use with a binocular viewer. Its retractable dew shield makes it quite compact for transport, measuring only 1145 mm in length.
