Still have some work to do but I'm much happier with my latest effort re focus in low light.

Post your sunrise/sunset

These were taken using two methods. The first method for almost total darkness was f11 and manual focus to a smidge over 1m on the focus ring. Once I had more light I used live view, zoomed in x10 and manual focused, keeping the fstop above 11 to maximise the DoF.

Thanks for your help and advice
