It is very stable. I have just checked the optimiser results and average error is just over 1 pixel with maximum of 3 pixels, so no extra errors due to the wind. You can actually see that there are almost no stitching errors. I always used guide ropes.
Thank you for the tip, Martin. This is something to try. Is it really very stable?
It is 12.5m high telescopic mast. I order it from here: http://www.totalmastsolutions.com/

Superb, Martin. I just added it to my favorites!
Just a question: what sort of telescopic mast did you get? Did you rent it?
