The Askar 185APO is an OTA with a 185mm aperture,1295mm focal length, and

f/7 native focal ratio. The Askar 185APO adopts a triplet air-spaced APO lens

design, including one piece of ED glass.

As a large aperture, long focal ratio telescope, the Askar 185APO was designed

with portability in mind. Due to the retractable lens tube design, the shortest

overall length is only 1081mm, the net weight is 14.9kg, and the gross weight

is 17.2kg (including the handle, tube ring, and dovetail plate).

The entire Askar 185APO tube is crafted using high-quality CNC machining

with anodized and surface spray paint treatments. The retractable design of the

dew shield, along with the enlarged locking screws, provides convenient usage.

The Askar 185APO has an extended 400mm handle with a special slot design,

making it also a base for installing a finder scope. The Askar 185APO has an

integrated design for the tube ring, the thumb screws enable easy opening and

locking of the tube rings. The dovetail plate of the Askar 185APO is the

standard Losmandy dovetail plate, which is compatible with most equatorial

mounts and bases on the market. The dovetail plate is designed with multiple

holes, which makes it easy to adjust the position. The length of the dovetail

plate has been extended to 400mm, which is more convenient for balancing on

the mount.

The rear lens tube of the Askar 185APO has an integrated retractable design.

We strengthen the overall stability and ensure that the optical axis will not be

affected when the lens tube is stretched, thus guaranteeing the quality of the

image. The retractable part also features a rudder-type locking ring that makes

it easy to loosen or tighten.

When the lens tube is contracted, the Askar 185APO can be used with a

binoviewer for visual observation. When the lens tube is stretched, the 185APO

can be connected with a specific 0.8x reducer or 1.0x flattener for imaging or a

diagonal and eyepiece for observing.

In terms of the focuser, the Askar 185APO is equipped with a dual-speed rack

and pinion large 3.5-inch rigid focuser, which can be compatible with most

motorized focusers on the market. There is a high-precision scale printed on

the 100mm focusing travel. The rear of the focuser features a 360° high-preci-

sion big rotator, along with precise scales for convenient adjustment and

saving of rotation angles, enabling precise rotation. It is also equipped with an
