Hi Sandy
I've got a HEQ5Pro too, and rarely manage to get a beautiful 3 point alignment done. I learnt early on its easier to load up a saved cal and sync it for the part of the sky I'm imaging in. If the object isn't dead-centre, its very rare I can't tweak it in one jump through the viewfinder of my DSLR (you may be talking about your DSI though I suspect).
Anyway, most of us with a HEQ didn't buy it for its pointing ability, but the price.
With price in mind, why not invest a few hours getting Elbrus going - its freeware? It took me a while to get my head around it properly, but its quite capable of correcting your pointing without having to sync on a known star with each slew to a new part of the sky. Once you've plate solved, you just tell it to sync with your ascom compatible planetarium software (or let it do it automatically). Be aware - big download to get the database.
