OK, this one was really a challenge... first, it was very windy. Second, I lost the guide star and therefore more than 1 hour was worthless... I don't know why... everything was fixed well. An acoustic alarm if the guide star is lost would be cool ;-)
And the object itself: very very faint. It would need much more lights... next time...
