Askar 1x field flattener for Askar 140APO refractor
The 1.0x flattener does not change the telescope's focal ratio itself. After connecting with the Askar 140APO, it still maintained 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 M92x1. At the camera end, it is equipped with M68x1, M54x0.75 and M48x0.75 three sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48x0.75 2" filter thread, which can be directly installed and used. The overall CNC machined, both end threaded metal caps prevent ash when not in use.
