Decision, Purchase and success
Thanks to all posters. I bit the bullet and decided to buy a Polemaster. I had some initial difficulties roughly aligning the tripod and identifying the Octans asterism but now have sorted those things out and am confident of getting alignment and ready to work in about twenty minutes.
On my driveway I incised a permanent true north south line determined by using the true noon sun shadow method whilst for field use I set up the tripod just using a decent compass.
I think the secret is having a reliable and repeatable method for setting up your tripod, becoming familiar with the Octans asterism and PRACTICE.
Paul I looked up the Sharpcap app and it looks very interesting and maybe later may want to see how it goes against the Polemaster one.
I am really only a beginner in imaging but was really happy when I saw my first star image of Canopus. (80mm Vixen?, Canon M6, 1 min, ISO 1600).
