Thanks for the detailed post Dave.

I'm going to give it another go tonight again. Once I have it sorted out I'm sure it's just a matter of writing down the steps and following the right procedure. Will start by doing a library of darks as advised. I could see a lot of guide stars available in the lodestar viewport even at 1/20s so it's not the lack of guide stars that were the issue. I guess everything connects as well, so I can't complain too much. Got that far.
