I had an SXD, not a GP-D2. PE wasn't anything to rave about, many here were clearly doing a lot better with EQ5 and EQ6 mounts carrying much larger scopes than mine, to the extent what I had was clearly a waste of time hence sold it quickly. As far as I was concerned it was good enough for visual observing, maybe a beginner getting toes wet in AP with a small scope, but not for routine AP where you expect it to "just work" reliably 90% of the time at focal lengths of 800mm. I'm not interested in spending thousands on gear and trips to dark sites - when the weather permits - to come back with bad photos.
