A New Era for Astrophotographers
Introducing the Askar N210, a significant addition to Askar’s N-series of Newtonian astrographs. With its 210mm aperture, the N210 advances beyond its predecessor, the N160, into a new league of imaging telescopes. In this groundbreaking moment, Askar presents its latest model, with its carbon-fiber tube, rack-and-pinion focuser, and electronic focusing support making it indispensable for astrophotography enthusiasts.
Specifications and Enhancements: Unveiling the N210
The N210 boasts a native focal length of 756mm and a 210mm aperture, resulting in a focal ratio of f/3.6. It comes with the inclusion of a 0.95x coma corrector that reduces the focal length to 718mm, enabling the system to operate at f/3.4. Ideal for APS-C imaging, this telescope is designed for serious astro-imagers.
A 210mm primary mirror crafted from high-borosilicate glass promises precision. This parabolic mirror, a staple in Newtonian reflectors, is supported by a robust structure, maintaining accuracy even during high-resolution observations.
Focusing on Coma Correction
Coma aberration, where stars near the field edge appear stretched, is a challenge for Newtonian telescopes. The N210’s three-element 0.95x coma corrector provides exceptional sharpness, reducing the focal ratio to f/3.4. Askar offers this accessory aligning perfectly with APS-C imaging requirements, ensuring crisp, clear images.
Innovative Mechanical Design
Askar’s N210 comes with mechanical features including a dedicated structure for mirror support with adjustable locking controls for optimal collimation. The updated secondary mirror assembly features a reinforced one-piece structure and pre-drilled holes for additional protections such as a rain cover.
Equipped with a dual-speed rack-and-pinion focuser with 25mm of travel, the telescope supports most electronic focusers. Its rotatable design allows users to fine-tune camera orientation easily, integrating seamlessly into automated setups.
Lightweight Construction
Utilizing a carbon-fiber optical tube, the N210 weighs approximately 7.9kg before attaching additional imaging gear. Its lightweight design doesn’t compromise on durability, providing the necessary support for demanding deep-sky photography tasks.
