collimation follow-up

Followed up with Manuel. Asked if he had checked the collimation of the 9¼ SCT. He said he hadn't.

I told him that, in general, SCT telescopes held collimation well. Implying that his was probably OK. Both Phil and I had checked it recently. So it should not have suddenly lost it. Unlikely Newtonian users who generally check it every time.

He asked if I could help on Sunday night. I reminded him that I was working. I suggested he check it himself. It was something that he really should get comfortable with.

I'm still curious why Jim said what he did... Perhaps I should chat with Jim.
