cant get focus... I am gunna ask the question we should have asked first up...
have you removed the lens on the webcam?
when i first started i didnt remove the lens and all i got was what you got. the telescope its self is a lens so if you are placeing the toucam with its own lens on another lens (telescope) they kinda cancel eachother out and you get zip... remove the lens and focus can be achieved.
of course if you have already done this that ignore my entire post

let us know how you go.
ps: switches? what the...?
