Why have a telescope that doesn't even track the sky??
It's cheaper, more powerful, more portable, more stable.
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.

- Prev by Date: As mentioned, a majority of the watch industry has gone quartz replacing the fad of mechanical watches that dominated the world since the 14th century. With the invention and innovation of quartz watches, you can now find high quality Gucci watches such as the 6105 collection for women and the 7705 for men.
