Halographic lasers ?

Has anyone tried out these new halographic lasers yet? Are they that much better than the dot lasers?

Thanks, Yvonne

Yes, I've got one. They are much more versatile.
Examples:

(1) You can easily tell if your diagonal is centered
under the focusser, by looking at the pattern of
dots inside the tube opposite the focusser.

(2) It is easy to find the center of the primary
mirror, if you don't have the center marked. Just center
the dot pattern around the periphery of the mirror.

(3) You tell how well the system is collimated by
looking at the pattern of dots coming out the
front of the scope. If any of the optics are off-center
(tube, primary, seconday) its easy to tell.

These EZ-collimators are also nice, though they only
have single dot. Sometimes I switch between hologram
collimator and EZ-collimator during collimation.

I think they are fantastic, they show you 10 times the information of single dot lasers!
