Well thank you very much for your kind comments, so my early morning paid off, it is a shame I lost 6 frames though, should have been more observant.
The clouds were very fine and hazy, and the guide scope still hung onto the guide star, so I wasn't alerted of the danger, well that is my story and I'm sticking to it
And Houghy, no mate losing Antares was an accident, I couldn't fine a good guide star so it had to slew the mount around a bit here and there till i could find on the lock onto.
