. I'm not exactly sure which telescope you have, but I'm assuming it is a reflector scope. If that is true you should have 3 pairs of 2 screws. Three should be tight. Those three hold the back of the telescope together. The other three that look loose, are adjustment (collumation) screws. They should be set correctly, and I would not suggest moving them. Please let us know if there is anything else we can do for you.
