Product description

The Askar 160APO is a high-quality astrograph with a large aperture.

The Askar 160APO is a telescope with 160 mm aperture, 1120 focal length, and f/7 native focal ratio

The large aperture of 160 mm gives it an inherent advantage in terms of light-gathering power, resolution, brightness, and contrast, allowing the photographer to gather more light and present more details and brighter objects in the image. Along with more light coming into the astrograph, the limiting magnitude can reach 12.8 mag.

The Askar 160APO adopts a triplet air-spaced APO lens design, including one piece of ED glass.

The Askar APO series employs special optical designs and multiple lens elements to correct chromatic aberration, naturally providing higher-quality object details and color accuracy.
In the refractor´s element structure, increasing the number of lens elements and designing lens combinations can effectively improve chromatic aberration correction. However, this also means increased production costs and design complexity.
ED glass, also known as low-dispersion glass, is a type of optical glass specifically designed to reduce chromatic aberration.
As a large aperture, long focal ratio telescope, the Askar 160APO was designed with portability in mind. The shortest overall length is only 883 mm, the net weight is 11.4 kg, and the gross weight is 13.6 kg (including the handle, tube ring, and dovetail plate).

The retractable design of the dew shield, along with the enlarged locking screws, provides convenient usage. The dew shield serves the purpose of protecting the lens from the impact of external and internal light.
The Askar 160APO has an overall lightweight design for the tube rings. The thumb screws enable easy opening and locking of the tube rings. Meanwhile, the base of the tube rings is heightened, providing more space.
The handle of the Askar 160APO has a special slot design, making it also a base for installing a finder scope. The handle itself is 316 mm long.
The dovetail plate of the Askar 160APO is the standard Losmandy style dovetail plate, which is compatible with most equatorial mounts and bases on the market. We extended the length and added screw holes, making the length 400 mm, which is easier to balance on the mounts. With the slotted handle, the spacing between the tube rings can be adjusted as desired.
