Re: What is the best collimation tool to buy.
Folks, you should be wary of "The Dreaded Star test". Most of use can't fathom the Suiter book and his math.? Also: Thermal equilibrium and seeing often will not allow a star test to tell you anything. At least for the former, not as you are 'setting up'.?
And you have to compensate for eyepiece and your eye's aberrations.
Just a word.?
THE NUMBER ONE THING newcomers need to know? If your scope is f/5 or better. Just t=do what you can. It'll be fine. Don't stress!?
If you are type A, maybe a f/7 or better telescope is the way to go before you blow a fuse! :)? Too many people lose too much time fretting over collimation when they should just be observing.? Once you have a few 100 (1000?) hours doing that, maybe you'll tell the difference.? You don't see ANYTHING observing Polaris for an hour while fretting over collimation. Except a nice double. :)
