Product information

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.
