Celestron Collimation Tool
Just fine. It confirmed whatever state of collimation I was in and that I could not have recognized myself.
at first i was not shure about this tool. they showed me the lazer tool but i did not have the money for that also my telescope is in really bad shape. so i went with this one and it was not that bad. iam very suprised how it performed and maybe in the future ill get the lazer but this tool works!
