Re: Collimation Issue
Thanks for the link. Very informative article. I wasn't thinking about basic geometry, I was just trying to follow the tutorial. I'm not sure what I backed out of though...I'm just trying to figure out what I'm doing.SkyHiker wrote: ↑Sun Oct 23, 2022 6:25 pm You rotated your laser and it stayed in the same spot so your laser is fine. Trust it, especially for collimating the secondary. You backed out for the wrong reason. The image of the secondary is not supposed to be symmetrical, from basic geometry. See Don Pensack's article https://www.catseyecollimation.com/pensack.pdf .
