Hi,
With my Synscan, it has to be aligned quite well first on the SCP before starting star alignment. I found it best to use a compass, in conjunction with the scale for latitude setting. It also means you need to get it pretty well levelled too. It seems to be a critical thing.
Initially I also found it helpful to do first a one-star alignment, then slew back to home position, then a 2-star, and slew back to home, then a 3-star. That seemed to progressively improve the pointing.
At first, only after all that folderol would it say "alignment successful". Now I'm getting more practised and I can cut out the 2-star step.
Even then, in use, if the go-to has slewed a long way round to some object, the pointing is much improved if I re-align on a nearby star in that region.
Cheers
