I'd be more concerned about vibration finding it's way into every
observation you make. If you were only using powers in the range of
20-50x, you might get away with it, but with the tube you're describing,
you'll be using higher magnifications and it'll "wiggle". Cold as hell to
touch in the winter, too.
