I find I can't use very much sauce with deconvolution compared to what I've seen in various guides (lightvortexastronomy, John Rista and the Inside IP book by Keller).
I'm using a range-star mask to just work on the target plus a star mask for local support - but usually I can only go up to about 10-15 iterations with really low global dark for deringing (< 0.001). Any more than that and the worms appears.
