Observing Summary:

Whole programme accomplished succesfully. 
I had to stop for an hour for high winds. (see details on seeing and weather conditions). However, it was the repetition of OB99042 and EB99001, so we didn't miss any object.
Charles, unfortunately the seeing got really bad when observing 47 Tuk. However, I decided to observe it in u band as well.
Differential magnitude of Aql X-1:
R=2.21
V=0.57

Some images look quite elongated because of the strong (35mph) winds throughout the night. Some other are really neat.

That's it.
