ASKAR 1x Full-frame Flattener for 103APO Telescopes

The Askar 103 APO comes with three optional premium accessories, a 1.0x flattener, a 0.8x reducer, and a 0.6x reducer. Introduced here is the 1.0x flattener， which is optimized for the Askar 103APO， and can provide more possibilities for telescope use.

The 1x flattener does not change the telescope's focal ratio itself. After connecting with the Askar 103APO, it still maintained a focal length of 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 44mm full-frame image circle. The overall weight is 0.58kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. At the camera end, it is equipped with M54*0.75 and M48*0.75 two sizes of adapters, which are convenient for connection. At the same time, it has a built-in M48*0.75 2-inch filter thread, which can be directly installed and used. The overall CNC machined, both end threaded metal caps prevent ash when not in use.
