Askar N160 f/3.4 is a fast Newtonian reflector telescope with a 160 mm aperture, designed mainly for deep-sky astrophotography. The optical system works at f/3.6 without the corrector and at f/3.4 with the included 0.95× coma corrector. The design supports APS-C format cameras, while the carbon fiber tube reduces overall weight and helps maintain mechanical stability in changing conditions.
