Askar Flattener for 120APO

The 1x flattener does not change the telescope´s focal ratio itself. After connecting with the Askar 120APO, it still maintaines a focal ratio of f/7. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.

The 1.0x flattener adopts a triplet design and supports a 44 mm full-frame image circle. The overall weight is 0.75 kg. The back focus from the M48 thread is a standard 55 mm. The front thread is M84x1.

At the camera end, it is equipped with M54x0.75 and M48x0.75 male threads - two sizes of adapters which are convenient for connection. At the same time, the built-in M48x0.75 (2-inch) filter thread can be used to install filters directly. The overall CNC-machined, both end threaded metal caps protect the flattener when not in use.
