....and I should have better collimated 30x100s then. It took me a while to get the hang of it, and I had a gusty wind blowing, but I worked on the collimation yesterday. Yes they were out vertically, enough to be the cause of the struggle my brain has had to feel comfortable with the view. Probably a tweak would have done it, but by the time I'd fiddled, I'd wound the two set screws right out and right in to see how it all works

. I found the active adjustment of the prisms is only around one turn of the set screws. Anyway, now I know and I think I have them right. But I think it collimates at different places, depending on the distance to the object? I started at about 300m, then moved to about 800m. So what about a infinite distance? It would be hard to do at night - unless some can point me to a bright horizontal straight line in the sky?
