Nice thread...
I have never actually tried LRD or any other D on planetary images. I know that it does help with my deep sky stuff sometimes.
I always apply the LRD to the Raws before stacking, and try to extract the PSF from a good star (or 2) within the image. However even with this approach I got mixed results so now I generally do not bother.
I was using the LRD within MaxImDL 4.
I think that the thoery is good but in practive there are many other factors (like seeing) that will kill your PSF. Any optical system will hava a known PSF that perhaps varies very little from session to session, so therefore one could generate a PSF on a night of exceptionally good seeing that can be used again... Pretty much thinking out loud here, so take it with a grain of salt!!!
Use what works & if LRD helps your image, then great!! If not, then hey at least you tried...
Keep it up!
Cheers
