Here is a crop of the area within the 42mm diameter fully corrected area of the RH200.

The sensor of the PL16803 camera has a 52mm diagonal which is way bigger than the fully corrected field of the RH200.
This is the field of a 35mm frame sensor

As can be seen by these crops I am pushing the optic way beyond its design limits.
