i think all of the smaller skywatchers dont have collimation screws.If you want to line up the laser with the centre of the objective you could try removing the focusser (3 screws normally) and rotate the focusser in the tube until the holes line up and see if this improves things.If not make the holes in the tube longer using a file so that you can tilt the whole focusser in any direction to achieve collimation.
