The Askar N210 is a large-aperture Newtonian reflector designed primarily for deep-sky astrophotography. Its 210mm parabolic primary mirror provides a 756mm focal length at the native f/3.6 focal ratio, while the included 0.95x triplet coma corrector changes the system to 714mm at f/3.4 and provides coma correction across an APS-C imaging field.
The N210 features a lightweight carbon-fiber optical tube, a 71mm minor-axis secondary mirror, and a dual-speed rack-and-pinion focuser with 25mm of travel. The focuser includes tilt adjustment and is compatible with electronic focus motors. A 400mm Vixen-style dovetail, multifunction handle, tube rings, and the coma corrector are included.
