I do not like to break my head with the instructions, there it went pretty well. The performances are amazing but you can never say enough that video use of the foot is almost indispensable. At maximum zoom, and in certain lights, one sees fringes but it is not an astronomical observation tool! I have gotten a video software package and I have fun like crazy small.
