Quote: The supplied laser collimater is of poor quality IMHO. If they go this route they will need to verify the collimater is collimated. Even after doing that it wobbles around so much it is hard to get a repeat placement of the laser on the primary. It goes through batteries like crazy.

Quote:A Cheshire/sight-tube combo is cheap, realiable, easy to use and gives better results than most people could manage without using some sort of collimation tool.

Quote:Lane,I agree with SteveG about the 8" AstroTech. I always preferred white telescopes, and the AT dobs sure look nice. I disagree, however, about the cheshire collimation tube business.Take a look at this thread ... How to Collimate your Newtonian ... near the top of this forum. This clearly leads to insanity. As I posted in that thread, this video here ...http://www.youtube.com/watch?v=yd3mjOr8rc0&feature=youtube_gdata_player
Quote:... is truly simple and easy to understand. I'd get some kind laser collimator. Personally I'd think this one from Agena would do the trick nicely, and it's only $49 shipped.
Quote:Your relatives' sanity and enjoyment are worth the few extra bucks this will cost over a cheshire. If you don't believe me, try reading through the first post I have above, then compare it to the video. A few dollars is well worth it.
Quote:That New Moon is really big for an 8". Sort of defeats the whole purpose of getting an 8" truss dob, which would be portability.
Quote:Quote:That New Moon is really big for an 8". Sort of defeats the whole purpose of getting an 8" truss dob, which would be portability. ???It's considerably smaller and lighter than the GSO 8inchers. It looks really TINY in the video to me!
Quote:For the scope itself, I'd go for the Zhummel or Aptura. But as foar as the laser collimater that comes with it--just heave it as hard as you can....that's as close as it should ever get to collimating your scope...
