The Askar N160 is an affordable Newtonian telescope designed specifically for deep-sky astrophotography. It has an aperture of 160 mm and a focal ratio of f/3.6. When combined with the 0.95x coma corrector included in the package, this results in an even faster focal ratio of f/3.4. The high-quality three-element coma corrector can be securely screwed onto the focuser and ensures optimal image quality right out to the corners of the frame.
The parabolic primary mirror and the secondary mirror are made of temperature-stable borosilicate glass and feature an aluminium coating. On the rear of the primary mirror cell are tension and compression screws that allow for tool-free adjustment (collimation).
Measuring 61 × 86 mm, the secondary mirror fully illuminates sensors up to APS-C format. Its tilt can be precisely adjusted using three adjustment screws.
A rack-and-pinion (R&P) focus mechanism with a fine-adjustment reduction gear is used for focusing. Once a screw has been loosened, the focuser can be rotated. This facilitates the optimal alignment of the camera and accessories, but does not replace a full-featured camera rotator. In addition, the base of the focuser features an integrated tilt adjustment (tilter), which allows the optical axis of the focuser to be precisely aligned with the optical path of the main lens. Thanks to the corresponding mounting holes, the focuser is also designed to accommodate the retrofitting of a focus motor.
Fine-adjustment rings (‘shims’) are included in the scope of delivery to ensure optimum back-focus adjustment.
Both the carrying handle and the viewfinder shoe offer simple mounting options for additional accessories. The telescope is mounted on a mount via a 230 mm long prism rail in accordance with the Vixen standard.
Carbon lens tube: The classic black carbon lens tube saves weight. This not only makes transportation easier but also takes load off the mount. At the same time, the thermal expansion coefficient of carbon fibre is considerably smaller than that of aluminium or steel. This makes the telescope's focus much more stable when is comes to changes in temperature.
