You've obviously never used one, or you would know that a gentle
nudge from time to time is all you need to track objects. It becomes
second nature in minutes.

Get an 8-10" mounted Meade or Celestron and you can have it both ways.

It's cheaper, more powerful, more portable, more stable. |

Cost. Some people don't need tracking. Dobs are a GREAT value for the money. |

I think that dobs are great, but I don't agree with this claim that they are
"more powerful, more portable, more stable". 1) I don't even know what is
meant by "more powerful". 2) Some dobs are very portable and some are not,
and the same can be said for other designs. 3) I don't see how they are
"more stable" - at public events folks are constantly moving the dobs off
target as they push on the scope, even if they intend only to focus.
They are cheaper, and if the optics are good provide excellent views.
While you can't always compare apples and oranges, with a Dob you do
get some conbination of more aperture per dollar, a lighter, easier-to-
set-up scope for any given aperture, and a mount that is often more
stable than all but the sturdiest (expensive and generally less
portable) equatorials.
The greater light-gathering power, and resolving power, combined with
low cost, made even a medium-sized Dob more interesting than the old
three-inch refractors, small SCTs, or 6-inch Newtonians that were the
norm back in the 70's and early 80's. |

I don't see how. I use a 10" dob and have owned several 8-10" mounted
SCT's. The Dob is much easier and less work to set up and break down,
easier to point, easier and more comfortable to use and sports a
smaller obstruction and shorter focal length for wider field and
higher contrast (better) views. For purely visual observing I prefer
it greatly to the complicated and persnickety contraptions that most
noobies call "telescopes" these days. Not that there's anything wrong
with SCT's. It's just that there's nothing wrong with a good Dob,
either, just depends what you want to do with your telescope and how
much time to have to get going each session and how much you need it
to do for you vs what you know how to do for yourself.

Some Dobs cost more as much as SCT's, so there must be other reasons.

if you think a big honkin yard long dob is portable you are delusional. |
