Regarding PE, I am not sure if you can use a DSLR.
Normally you would use your guiding camera (any webcam will do) and point it to a (bright) star. Then PHD analyses the star drift for an hour or so (for several worm rotations) and creates a file containing this information. Then something like
PECprep (part of free
EQMOD package) can be used to analyse this file and create a PEC file for EQASCOM. I am not sure how to upload it to EQ6 but it should not be too difficult (I believe?).
By the way, apart from a webcam you will need some sort of adapter to mount it to the scope.
