Collimated all day. Long story short. I unscrewed the main bolt too far on secondary. The mirror fell off! I was terrified it was broke.
Didn't break, or slide down to hit primary. I accidentally grabbed the secondary earlier with finger tips and was pretty sick over that.
So, since it fell, i cleaned it real good (had finger prints on it). I used a big flashlight and pointed my scope at it.
I could see the focus tube was not aligned ...far off. First time I could really tell (had to do with the bright flashlight centered on the primary donut.
Now, all concentrics aligned and the focus tube aligned also. I tried putting in the cheap chesire (before it was always an egg shape and not a complete circle opening).
Wow..........it's a perfect circle now and so is all the other concentrics. The cross hairs line up way way better than before.
When i turn the chesire though, the cross hairs do migrate some, but that's expected from focus tube slack etc.
For most part, i never had it so aligned before. I will test it out tonight.
So glad it's in perfect shape.
