Dan Orion XT8g If your dob isn't broke, fix it anyway. Don't tell me what I want to hear, tell me the truth.
We mostly come out at night... mostly.

Quote: As someone already said, if you have GoTo, you can always decide not to use it. If you don't have it ...
Quote:Some Goto mounts can be used effectively for starhopping but many cannot. In general equatorial Goto mounts work well for starhopping, they have eq north tracking mode and in that mode, its just like using a mount with a clock drive. But in general, alt-az Goto mounts are not designed to be easily used without the Goto, the motions and action of the unlocked mount is poor so one is dependent on trying to slew the scope using the hand-controller, it's not easily done... In case of this particular scope, the XT-10g, it seems the motions are stiff and not smooth.. Jon

That depends on your attitude and goals, I suppose, like anything else. I don't think it's fair to imply that using a GoTo system somehow makes astronomy less rewarding.-- Chris

From what I've seen, folks engaging in any hobby activities tend to concentrate their efforts on things that interest them. Thus, folks who enjoy finding objects spend more time finding them and folks who enjoy looking at objects spend more time looking at them them. Nothing else would make sense. Anyone who concentrates on an uninteresting (to them) activity because someone else thinks they should is missing the point of having a hobby and is getting less out of it than they could be.

Quote:FWIW, I was able to polar align my daughter's Sirius EQ-G mount the last two nights in about 10 minutes. (I've never had a GEM mount, and I've not had a telescope at all for more than 35 years.) And this was in a much less than optimal location (front porch of my house, with limited views in most directions and significant LP).
The keys for me were reading the manual quite thoroughly and practicing with the controller in the bright, warm living room and having Sky Safari running on my iPad so I could figure out where the named stars the hand controller was suggesting were located. It also helped to do the alignment just after sunset, when basically only the brightest stars were visible -- it made it easier to pick them out.
Quote:i have no doubt that with use and practice you get good at it.
Quote:setup still takes anywhere from 3-6 times longer than a manual dob. the hardest part of setting up a manual dob is carrying it the goto dob would be easier than a goto EQ mount no doubt about it but one still has to go through the star alignments. just making sure the OP know what he will have to do to use this scope.
Quote:If you even start thinking the goTo will be bad for a beginner, then you are already resigned to the fact it will be bad for star hopping.I started star hopping due to extremely bad light pollution at my place before I went goTo. During that time, with help from my kids, when we discovered galaxies or nebula, the feeling was great. Same can't be said about goTo's. But if you are inclined to learn, then even goTo can be useful.
