Having hopefully done a better job of aligning the
secondary, I went after the primary. After 2 hours
of work, it seemed that the stars across the entire
image were fairly round. Then came the big test -
seeing whether the stars would stay good as I rotated
the camera to other angles. The stars looked
consistently good whether the camera rotator was
at 0 degrees, 90 degrees, or 270 degrees. This was
the closest I had come in my year of owning the
scope to an acceptable collimation. This isn't yet
perfect, but it seemed good enough to be encouraging.
However, the story continues in the next couple of images...
