Hi Gang,
I,ve had a few Televues in my time and even though buttery smooth some drawtubes can slide when the scope is pointed too high.By tightening the lock screw just a little you will find it mars the chrome drawtube with very light marring or scratches.As most of you know I,m a fanatic about my equipment.Is this common and I just live with it.I know, Dave don,t worry so much about the small stuff and just enjoy the scope.
Thanks, Dave
