Hello axs, I don't think you will get much help without identifying what type of machine you're running (brand, size, power, etc).

And it would probably also help to add details about the brand of tube and power supply you put in, as well as what prompted you to do that.

Best of luck.

Check, not just look and see if your lens is tight in the holder. Or how clean is the lens at the output of the tube?

to expand on what Bill said check all your mirrors to see that none are loose. Definitely looks mechanical
