    Default Haven't Collimated my Reflector In A While Because...



    I got my scope in late December of 2010. Since then, I've only collimated it twice. The last time was probably in early February, but when I go out to view the sky, everything looks fine.

    So my question is, should I collimate my scope even though it doesn't look like it needs it?

    Do a star test. If that looks fine you likely don't need further collimation.

    Yeah I tried a star test. Everything looks fine and aligned.

    Is this normal?

    Not terribly unusual for a solid tube reflector. I always double check my Z10 at each session, and while I usually have to tweak it just slightly, I have had occasions when it was still good. But with the truss dob, I definitely need to re-collimate because things can get a bit off due to the assembly and dis-assembly process each time.

    If it ain't broke, don't fix it. You should check it every session with a star test. If it's fine, it's fine.
