Hi Matt,
Collimation like that image of Antares, I would say what ever you do
DO NOT TOUCH IT!
You will not see the difference in the focussed image. Its called splitting hairs, chasing rainbows. But if you gotta do it to put your mind at rest then because its a free world, go for it.
As a well known prophet (who lives down the road) once said. Seeing rules.
