Thanks for clarifying that for me Brian.
Using a star in Orion’s belt should work well for me as it‘s in the darker part of my sky as I’m north of Perth. Point noted on small adjusted as this was one of the things I was doing wrong when collimating my dob until I learnt how.
And am I correct in saying I should wait for a good night for in focus collimation?
