[QUOTE=fok4tel;315354][[/FONT]
[FONT=Arial]I am using a laser collimator. I find that it is only good for aligning the secondary, not the primary, because the tilted disc in the collimator can only give an approximate alignment of the primary. After using the laser collimator, I normally confirm with my own eye that collimation is done properly (by looking through the focuser hole at the image of the primary reflected by the secondary mirror). Scotts, is this a good method of getting the collimation right? I’ll check the other threads about collimationQUOTE]
There are several good sources of information on collimation that can explain/demonstrate much better than I...Andy Shotglass is a good one overall and Cloudy Nights has a great deal of information about "technical aspects" of collimation.
With respect to tools...I generally rely on my Orion collimating eyepiece that I got from Bintel (a low tech solution)...after I am happy with this, I "check"it with a "Quality" laser collimating tool...You must be careful using "just a laser" as they can get out of collimation themselves (at least the cheaper ones can).
I have invested in but have not set up and used yet, a Catseye Collimation Tool set...which by all accounts takwes accuracy to an even higher level.
Good Luck!
