Thanks for the image Asi and for the manual. I have a much better idea on the settings but not getting frames anything like as clear as yours. I get a lot of shimmering which i am thinking may be heat haze coming from the roof of ours and the neighbours house, does this sound reasonable? It looks like cloud going across and can't get a good focus (definitely no cloud though). I think I will have to do a late night in a week and see if that makes a difference.
