Askar Flattener for 103APO
The 1x flattener does not change the telescope´s focal ratio itself. After connecting with the Askar 103APO, it still maintained a focal ratio of f/6.8. 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 0.58 kg. The back focus from the M48 thread is a standard 55 mm. The front thread is M84x1. At the camera end, Askar has equipped the flattener with three sizes of adapter - M68x1, M54x0.75, and M48x0.75 - for easy subsequent connection and use. 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.
