Collimation Question
This may sound a bit odd, but what happens to the image when your telescope is out of collimation. Everywhere I look people say make sure the scope is collimated and they are repeatedly doing it to their own. No-one that I have seen has explained the effects of a poorly collimated scope.
I have not yet collimated my 10" Dob. It is as I got it from the shop. I can see crystal clear images of Saturn and I can see amazing images of the Moon.
Does this mean my scope is already correctly collimated? I am a little wary of attempting a collimation until I see someone else do it. I think if I start adjusting mine I may make it worse for no reason.
Can someone please give me a basic explanation of what happens to the image if the telescope is out of collimation. Is it blurry and unfocusable? Is the image off centre? Can you see no image at all? Is it only important at higher magnifications?
Sorry if this sounds like an obvious question, but I am a little confused.
