Thanks folks, I appreciate your comments.
I had approx. 45 mins to set up and get ready, which sounds a long time but when you have to haul all the gear out set it up, boot the PC, make all the connections, align, focus, etc. the time just whizzes by.
I have 3 pads in the back garden where I place the tripod feet so these help me get ahead of the game and on the day, everything just worked 1st time round, making it a success.
If just one thing had gone wrong where I had to re do some task or procedure, I’d have enjoyed a visual over pass and missed the shot.
Cheers
Dennis
