Depending what type of image you intend deconvolution on but in my experience deconvolution works best on mono CCD images usually only on the Luminance image and sometimes on either 1 or all of the RGB images. Its a good way to make say the blue channel star sizes match the other RG or whichever one has larger stars if any.
It reduces red rings around stars after the colour combine if you match the star sizes. Marcus Davies put that technique out at AAIC 2 years ago. Quite a useful piece of info.
Also deconvolution works best multiscaled as per Ken Crawford tutorial. You do several versions on the luminance at various strengths and then layer the various strengths in. Decon too hard wrecks the stars and leaves sharpening halos. PixInsight has decon. I don't know for sure but I suspect it may have the best version of it like most things PixInsight.
Decon works best on oversampled images as well plus images with lots of hours of exposure.
