    I didn’t understand the third ingredient for the cleaning solution. Can you please tell me what it is?

    As of now, I have 101 dollars. I’m saving for an XT8 + Collimation laser + eye peices.

    Collimating every time you use a scope is a bit excessive. I would rather enjoy using the scope, than fiddling. I only do it when its needed, a simple star check will let you know

    Newtonians are like musical instruments, they require tuning up ever so often, when you see that the image is not what it should be by using a method called the star test. There are various tools made to help with this collimation, each tool has its own quirks as well. It is a skill that anyone with a Newtonian will need to develop. You may think you don’t need to learn how to do it, but then the scope will get bumped or a kid will turn the mirror knobs, your crisp image will turn to mush.

    I agree – I have a laser collimater.
    It was only $120 & it ensures that my
    mirror is aligned correctly.

  8. rednavy5 says:

    Advising people to rarely check the collimation of a Newtonian is absurd. Most people recommend doing it every time you use it (I do).
