Yes, but...
I use Saturn as my reference at high magnification, and I'm a bit off center still, but not much.
There's a local group here in Sacramento that is really into building there own and showing others how to, as well. I'd like to meet up iwth them some time and have someone check out my scope and give me some tips on doing the collimation. I can't seem to ever get it perfect.
I've read several references on line, but for some things, nothing beats someone showing you in person, I guess.
Regards,
Pex
