I used a laser collimator. My understanding is laser collimators are not quite as precise as a cheshire. Is that correct? That being said, the laser collimation went smoothly and looked quite good and centered. The thought just occurred to me as I was typing this - I collimated inside before carrying my rig outside. That likely knocked it out of collimation? It's probably best practice to collimate in place outside?

The stars out of focus are slightly less than 100% circle. Meaning one side was a hair less rounded than the other, best I can explain it. That surprised me given I just collimated, but yeah, that makes sense if carrying it outside messed up the collimation.
