Askar 103APO f/6.8 Triplet

Askar 103APO is an OTA with a 103mm aperture, 700mm focal length, and a 6.8 native focal ratio. The 103APO adopts a triplet air-spaced APO lens design and contains one piece of ED glass. The Askar 103APO is a detachable lens tube design, and with the rear segment lens tube removed, the 0.6x reducer can be attached to reduce the overall focal ratio to F4. At the same time, a binoviewer can be used for visual observation. In terms of mechanical design, the Askar 103APO features two finder bases, a special slotted handle, a 290mm Vixen-style dovetail plate, a large 3.3" dual-speed rack-and-pinion rigid focuser, 360° high-precision graduated rotator, and overall CNC machining with anodized and painted finish. The Askar 103APO has three optional advanced accessories, 1x flattener, 0.8x reducer, and 0.6x reducer. All three accessories come with built-in 2" filter threads for direct filter mounting and use. In addition, all three accessories are equipped with M54/M48 adapters, and the 0.6x reducer comes with an additional M68 adapter for easy attachment.
