Second row first coulomb
you may baulk at the price but yeah if your mirrors are not aligned correctly you might as well pack it away and enjoy the evening with SWMBO.

If you cant afford this type of tool for now, just collimate your laser and use that for the time being. Look up on the forum about collimating your laser there is a lot of knowledge already in print so to speak
