Thanks everyone for the quick replies.
My primary scope is the Orion SkyQuest XT10 Classic Dobsonian, 10",
254mm aperture and 1200mm focal length, F4.7
The F4.7 is a fast mirror right?
Rick what did you mean by "unless you colimating a fast scope, the
difference is not that noticable." Is the laser collimator better or
worse to use on a fast scope than other methods?
I'd bought the Orion laser collimator and days after I received it I
saw they advertised the Deluxe one with the target on it for aligning
the secondary. Debated about exchanging it but in the end kept the
lesser model. Just seems I can't quite get things lined up correctly.
I know I need to just bring it to one of the Star Parties (I'm a SAC
member) and ask for some help. But I was just curious if the laser
collimator was a good tool or an expensive, fancy toy for "quick &
dirty" collimation.
