Thanks for the kind words.
I did take flats -

I took many flats for each of LRGB.
I did that the next day & I tried to be careful to make sure the camera didn't move from it's previous position.

I don't know why?

I'll leave the gradients alone and move on to my next adventure.
I am actually set up ready to go for a dark site -
it's just the Cloudy skies that are stopping me.
