Following the adjustment of the secondary with the laser,
this image of an out of focus star shows a concentric
pattern, apparently confirming that the secondary is
well collimated (though, it should be noted, I had
seen the same result early with trying to collimate
this scope, and the mirrors were clearly not lined
up right, since I still did not get good star images
in focus. I believe that earlier, a mis-aligned
primary may have been making this test unreliable).
