Does anybody have experience with an ADC?

I understand this device  is installed within the optic train somewhere before the imaging camera. (at the cost of the backfocus)

I usually try to compensate the RGB color distortions in FITSWORK(4) using  the function 'color layer adjust'
It's pretty simple, you create one or two rectangles over regions of interests and then execute  the a.m. function.

It works fine for me, especially on planets. But I have no idea how this compares to an ADC
