Hi again. Thanks for your reply. I'll check the spacing and see what happens.
Hopefully there will be some clear sky here on the weekend to test these things out.
As for the drift alignment issue the website below is quite interesting. I believe the simulator training helps before going out to do the real thing.
I'll do this as well and see what improvement it makes.
