Collimation will most often involve adjustment of the rear, or primary mirror, and not the secondary mirror, which is situated in the middle of the corrector plate at the front of the scope. There are 3 screws on the primary cell on the back of the Tube. Adjusting these screws (very *very* slightly, I might add..."a little goes a long way" when collimating) will change the angle of the primary mirror. Simply go to www.google.com and look for "Maksutov Collimation", "Catadioptric Collimation", or Cassegrain Collimation" and you are more than certainly going to find instructions. I suggest you get a collimation eyepiece (the cheap route) or a laser collimator (which will run about $100). Collimation is something every telescope owner should do, as it will drastically bring back both focus and contrast. Good luck, and don't be afraid...If you were a doctor, it's not like doing a heart transplant, it's more like prescribing tylenol.
