HCG mode is already x5.8 gain, the band noise can be more emphasized.
And this is the HW issue, the manufacturer must take care the wiring for AVDD and also the analog signals to minimize the ripple noise on them.
and put the decoupling capacitors in proper way.
Can you probe the AVDD and compare the wave form between IMX477 and IMX462 board?
If the AVDD of IMX462 board is not clean enough, it is not suit to the astrophotography application.
