How to Collimate a Newtonian Telescope Spending Zero Money

No, you don't need to spend hundreds of your hard-worked money to get a good collimation for your Newtonian telescope. But of course, this may come with a price: your patience. You'll need to take some time and put great effort if you want to get good (even perfect) results. This article assumes you have some basic tools, like a pointed scissor and a Phillips screwdriver. You realize your Newtonian telescope is out of alignment if you see smudged (not blurred) images of stars and planets under high magnification, almost as if they were comets. At this point, your scope needs a collimation. If your image is simply blurred (not smudged), the problem probably is in the seeing conditions (air turbulence, halo, ice crystals in high atmosphere, etc.) or in your magnification lens; in this case, don't start messing around with collimation, or you'll find a huge pain in the neck.
