unpleasant thoughts

I noted slight differences in the RA and Dec positions between the GoToStar hand controller and Stellarium. I had a sinking thought that the GoToStar is out of date. And will get worse. This product is dead-ended. No more firmware updates.

All this assumes that goto slew coordinates are based on "current" RA and Dec values versus J2000...

Are these differences a problem? Would it amount to a target being out of the eyepiece? Or just off-centre?
