Im having hard time adjusting the ADC from ZWO to correct settings

Ive found it quite challenging to set the ADC correctly, it sometimes takes me up to 30 minutes to do so, are there any good reliable methods for setting it precisely without taking so long?

Ive tried using the FireCapture’s ADC assist tool but that usually takes very long, the worst part being the window of dispersion analysis doesnt update, so i have to repeat the cycle of adjusting the ADC, slewing, reopening the FireCapture’s ADC tuning window, over and over until its good enough

If you turn the brightness and saturation way up in the main preview window you will see a live view of the planet with a bright red crescent on one side of the planet and a bright blue one on the other side (assuming your ADC is not perfectly aligned already). You can then watch as you adjust the ADC until the appearance around the whole circumference of the planetary disk is as uniform as possible. Then turn the brightness and saturation back to normal. If you image long enough that the altitude of the planet changes significantly it’s easy to repeat the process as often as needed.

I’ve found this method to be a lot easier than the ADC tools in either FireCapture or SharpCap.
