Another experiment, I begin with 30 seconds, then 60s, then 90s, now 120s and more darks. Quite pleased with image but pointing an issue as clearly this a bit humdrum area of sky also only 10 lights as first 12 images also take nice image of bottom of roof overhang which I blame on holiday season and too much toasts! However:

plate solve
darks works nicely
more stars with longer sub time

Set up pretty quick and polar alignment good. So I happy with result, next next 150 seconds and better pointing. Not most spectacular for sure but feel as making progress incrementally.
