Askar Flattener 1.0x for 140 APO

US$ 350.13

Not in Stock: will Be Backordered

Short Description

The 1.0x flattener does not change the focal ratio of the telescope itself. After attaching it to the Askar 140APO, it still maintained a focal ratio of 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 44mm full-frame image circle. The total weight is 0.75 kg. The back focus from the M48 thread is a standard 55mm. The front thread is M841. At the camera end, it is equipped with adapters of three sizes: M681, M540.75 and M480.75, which are convenient for connection. At the same time, it has a built-in 2 inch M48*0.75 filter thread, which can be directly installed and used. The entire body is CNC machined, with threaded metal caps on both ends to prevent dust when not in use.
