    Default Collumation with Threadlock?



    New to telescopes, so I'm building up the nerve and knowledge to try collumating for the first time. I'm wondering if using blue threadlock on the screws of a beginner scope would be a good idea to keep the mirrors alligned.
    Is there any reason why this would be problematic?

    Threadlock is not permanent. It doesn't set fast, so there would be plenty of time to adjust mirrors. Once it is set, the screws would be less likely to move.

    I've never seen this recommended, so maybe I'm missing a fundamental concept. Thanks for your input.

    You will definitely NOT want to do that. The mirror will soon need to be collimated again soon even if you put that on and it would need to come off to collimate and likely would damage the threads in the adjustment screws trying to remove it. It will not help it keep its collimation any longer and will only be a hindrance.

    I think you should give us more information about the specific type of reflector you will be collimating and why you feel the need for theadlock. I did a total rebuild of a small reflector, for example, and it had 6 adjustment screws on the primary mirror cell. 3 for adjusting the mirror and 3 to lock the adjustment. I added 3 springs to make them to make the adjustment screws spring loaded and this made collimation much easier. I did feel that it was still not secure enough so I added 3 lock bolts to the lock screws to secure them, these are easily loosened to do collimation.

    Sure! I have the Celestron powerseaker 127eq. I have seen posts about doing exactly what you describe with the springs and was thinking about adding that modification as well.

    I don't necessarily feel the need to add threadlock. I just like to tinker and build a better mouse trap sometimes. I know with my bicycles i always add threadlock to important bolts i don't want moving around.
    And worse case scenario, I end up breaking something and have to buy a different (better) scope. Lol.
    Reaching out to see if anyone had tried before, and start fun conversation. Thanks to all the replies.

    Any precision instrument needs to be adjustable in order to maintain its precision. The threadlock would limit your ability to maintain the precision of your scope, turning it into a nonprecision instrument. Don't do it.

    Great point about precision! Learning a lot here, including the correct spelling of "collimation"

    This brings up an interesting point. Perhaps if we knew WHY a Newtonian got OUT of calibration so frequently it would become clear. Any takers? Lol! Bill

    And, if refractors and CATs were sealed better, and nitrogen purged, maybe less problems? Bill
