I found it:

And here are the 2 images he posted using a Microline 11002 camera.

The first image shows nice round stars, the 2nd shows some small amount of coma in the corners.

11002 chip is the same width as 16803 but half as long. I think its a good guide as to what to expect with a 16803 flexure issues not included. It seems pretty close to being spot on. Perhaps the spacing is not quite right.
