    I've known of skilled observers who said that GoTo roughly doubled the amount that they could see. It means that they can concentrate on the view rather than on trying to keep the view in their eyepiece.

    I think it is sort of like having a good observing chair. It does nothing for the optics - but it has a lot to do with your ability to use the optics effectively.

    But everyone is different.

    Are Goto systems smooth enough to avoid vibrations caused by the motors?

    The best advice I can give you is to JOIN a local Astronomy club and start attending their star parties === you will get to look through the member's telescopes and ask question.

    And GOTO and motors do NOT affect the view at all-- in fact motors will keep the object in the eyepiece for LONG periods of time. Remember that the sjy moves 15 degrees per hour.

    If the price of the two telescopes was pretty close, I would be tempted to go with the 14 inch with go-to, but considering that you have to pay $650 more for the telescope with two inches less aperture—just to get the go-to capability... now I'm not so sure... (Telescopes dot com sells the Orion XX14g for $2500 and the Meade LightBridge 16 inch for $1850)

    I agree that tracking would help your ability to see better, just like a nice observing chair does. It would be nice to be able to sketch what you are observing without worrying about keeping it centered too …but is it worth $650 plus 2 inches of aperture? I don't think it would be to me.

    What Joe said.

    Truly, an astronomy club can be a wondrous thing. The potential for learning is usually immense.

    I didn't find that this held true for me. I came from powered equatorial mounts to a Dob and now would never go back.
    Tracking with a manual Dob is not something you're even conscious you are doing. An experienced observer is too busy concentrating on the object.
    There is just no way any goto can double what you can actually see.
    Most objects you are using nowhere near enough power to make manual tracking even a slight problem.
    To be comfortable when observing is important but once this is achieved whether the scope is goto or not is immaterial.
    I do not believe a totally inexperienced observer could see anywhere near the detail that an experienced observer could, if he had goto and the experienced observer did not.

    To answer your question about the difference in light gathering ability:
    Going from 10 to 14 inches is a 96% increase in mirror surface area.
    Going from 10 to 16 inches is a 156% increase in mirror surface area.

    This is all good info. In due time, when I actually do start & finish my obs, I am planning on a larger Dobs. I've been thinking of a 16" & too bad Zhumell doesn't offer theirs anymore, but I do in fact get frustrated at finding an object, then when going back to find it again, I fail. I like to search for objects ... to a point. I'd rather spend MORE time looking at 'em just the same.
