You’ll also notice adjustment screws on it. You’ll see that it’s held in place by an object such as a glass pane. First, you’ll need to locate the secondary mirror that’s mounted on the front of the telescope tube.If you have a reflector telescope, which makes use of two mirrors in its design instead of lenses, then you can try this quick way to collimate it. Although it’s accurate, it can be a little tricky for beginners to master right away, but you’ll get the hang of it! How To Collimate Your Reflector Telescope The above test is known as the “star test,” and it’s completely tool-free, which is a bonus. When you look at the star, you should see circular rings around it when it’s out of focus, but you should also see a bright center when it’s in focus.Remember that temperature changes can affect how your telescope functions! If you notice what can be described as bleeding edges around the star, that’s a sign your telescope needs to cool down, so you’ll have to wait for it to climatize outside before proceeding.Use an eyepiece (or one that’s used with a Barlow lens), so you can increase the magnification of the star to around 200x or more.Make sure you do this on a clear night when there’s no haziness in the air, as that could interfere with your image. If the circles you see are not concentric, then your telescope needs to be collimated.Įasy, huh? Extra Notes When Doing This Test
