Were you lucky enough to get a new telescope for Christmas? If so, I'm guessing that if you're reading this then you may be getting annoyed that you can't see anything through it or you may still have to unwrap the thing, daunted by the astronomical learning curve that lies ahead. Using a telescope for the first time isn't always as easy as it sounds, but fear not! This Discovery News "Telescope Primer" will get you started so you can not only enjoy 'first light,' but also get your new 'scope ready for searching out countless wonders in the night sky. Which Telescope? First things first, what kind of telescope is it? Take a look down the open end and you will either see 1) a lens, 2) a lens and a mirror or, 3) just a mirror. If it's either of the first two then you can skip the next bit. If you have a telescope with just mirrors (3) then you have a reflecting telescope and you will need to check its collimation! Oh no! I hear you cry. But don't panic! It's not as scary as it sounds; collimation just means you need to check the mirrors to see if they are all aligned properly. If they are not then you will not get the best image. Read the Rest at Discovery News.
