You will need to focus in on the slide. There should be 2 1" diameter knobs on either side of the stand, and just to the rear. Those knobs control the height of the stage (where you slide sits). Slowly raise or lower while looking into the eyepiece. At some point something should be see, if the microscope is working properly.

Sometimes it is easiest to start with the lowest magnification. On the outside of the objective (little lenses hanging down that can be rotated) there should be some numbers written on them (usually 4, 10, 40). Those numbers reference your magnification. If you multiply that number by the eyepiece (10) magnification, you will get your total magnification, so start out with your 4x. It will give you the largest field of view, so it is great for finding whatever it is that you are looking for on your slide. It is also the easiest one to get focused. The higher you go in magnification, the smaller the field of view, thereby the more difficult it is focus in on your sample.

YOU MUST align the small finder scope with the main tube.

Point the scope at a distant object like the top of a telephone pole. GET the top in the center of the eyepiece in the main scope.

Then without moving the scope-- adjust the cross-hairs in the small finder scope so they line up on the same object.

Eye piece on my Bushnell rifle scope is loose. What could have happened?


There should be a lock ring that you need to snug up against the eye piece. Vibration can sometimes cause this ring to come loose.

Not worth repairing-- a new focuser for your telescope would cost as much or more than the telescope-- unless you can find a discarded telescope of the same model..... for parts.
