Hello folks, a PSA regarding Collimating your scope
As we all are well aware, Newtonian scopes require collimating to be able to provide the best views a given scope is capable of. A fundamental aspect of collimation is utilizing a mirror’s center point as the visual cue to indicate when the mirrors are properly aligned (a bit of simplification, but appropriate for our purpose here).
Many of us probably assume that the mirror’s center spot is accurately placed during assembly and collimate our scopes based on that assumption. But…..
I recently removed the mirror of my OneSky and checked the position of the factory applied center spot on the mirror.
It was off by about 1/4” (6.35mm) on a 5" mirror. So, if you want the best views possible, don’t assume. Verify that your center spot is accurately located.
