Some folk use an auto guider to keep the object in the FOV. FireCapture supports this for planetary, although it doesn't require specific support IMO.
I find that when I polar align properly the planet will stay pretty much centred. If I just roughly polar align, it's a bit like playing a video game with the Hand Controller
If you have the cable to be able to use EQMod, it might be worth trying that as you can increase/decrease the tracking rate in small steps and see if it's the HC that has tracking problems.
