First my collimation seems fine, im sure its pretty good.
But if i can improve it i would like to.
I have used the out of focus star method and the big donut looked pretty perfect. I blew it up as big as i could on the screen and got my ruler out and i adjusted it just barely, hopefully improved it.
i saw somebody post some pics before and after with the tri mask and it looked pretty impressive. then i read that its better to collimate while its in focus rather than out of focus, and that makes sense to me.
Ive heard bad things about lasers so i dont even want to bother with that, sounds like they are not perfect.
