Hi,
It's the worry wort again. I noticed a sound when moving the ota upon investigating its source I noticed that when shaking the tube, a shaking sound comes from the objective side of the ota. The lens cell is tight. Any ideas ? Is it normal? If not, what could it be and what should I do about it?
