Hello. I am trying to reproduce the geometric image analysis result using Huygens PSF in triplet lens system. (telescope)

I obtained PSF at the same field position using Huygens PSF and convolved with the image file that was used as the input for geometric analysis (uniform or gaussian source).

However, they always look quite different. Is there anything I am missing? or is it expected result? If it is expected to be different, which result should I trust?

Thanks.
