Dithering takes no extra time in my case.

I use a 10sec interval between exposures with dslr camera control in ImagesPlus. Dithering with PHd2 takes place at the end of an exposure automatically. Guiding and the next exposure start simultaneously.

Even manually, one can watch the PHd2 exposures and move the mount a random few pixels. Then restart guiding and watch the graph till it settles and then start an exposure. The settling of the mount must be an issue - you can assess the settling timespan and use that as the interval between exposures.

Then in post-processing try Drizzle.
