The word deconvolution means to reverse the effects of convolution.
Convolution here means the process of averaging pixels based on its neighbouring pixels.
So deconvolution is removing the averaging or blurring aspect. Not sure where the averaging process is occurring in an image that is taken at 1x1 binning but thats what the word means.
As mentioned it is similar to sharpening but it seems to recreate the star image and shrink it more than simply sharpen.
I find doing it on all LRGB subs produces good effects. Especially on galaxy type images or close up type images where the stars can be large and distracting.
On widerfield images it isn't worth doing.
I click on several stars to find the one that is tightest and then run 40 to 60 iterations (repeats). It takes a while - like 5 minutes on a large image or longer.
