I'm glad that link on SCT collimation basics was useful to you.

Hopefully it'll all come together for you soon and you'll gain the
control and confidence to do a good collimation job on your own scope.

It's so cool the first time you do it yourself and it really works.
Images get crisp and sharp, details come out of the haze... You'll
get it soon, Jean.
