The Askar N160 is a Newtonian reflector with a 160mm aperture and a F3.6 native focal ratio, designed for deep-sky astrophotography.
With the included 2-inch 0.95× coma corrector, the system focal ratio is optimized to F3.4. This coma corrector features a triplet air-spaced design and threaded connections, allowing it to be securely attached to the focuser.
The N160 supports APS-C format imaging and delivers excellent star performance.
