I've been following you guys on youtube since beginning this year, and I really enjoy and learn from every video you post, thanks a lot.
After I dropped my (vintage) Celestron C8, I bought an Orion8 F/3.9 - I have to say, a bit inspired by you, though I don't think I'll ever reach the level you're on.
In one of your videos you demonstrate that you collimate the secondary in less then 2 minutes. Me, even after 2 hours the laser dot is still not in the center of the donut. Other info on the web sort of indicate that it's a trial and error proces. Do you have some advice for a rookie like me, on how I can collimate my secondary under 15 minutes?
