Hi yes, I did find the focal plane with the paper as suggested, am just waiting to check with the webcam without the lens and without the finders objective.
i did try it with an slr as well without its lens and looks like i do have sufficient infocus for the webcam. this is the finder on the bintel 8" dob newt.
will post results. waiting for the sky to clear as well.
thanks
