If you have time, make your own. There are *many* sites that do just
that and will give you the HOW TOs. The flexibility in making your own
is that you can add stuff nilly willy as desired and at your cost and time
and not that of expensive alternatives.
Google: "Build your own telescope" and there is a lot there.
My ideal telescope would be that having remotely controlled gizmos
such as a high res. ccd attachment and easily removable if desired.
One advantage of a ccd attachment is manual or automatic digital
pictures, motion control and detection with automatic snapshots based
on pixel changes by percentage of change or deltas, automatic sky
positioning, automatic object tracking, just to name a few. All of this
gives you all sorts of flexibilities, osit.
Imagine if you will to let your automatic telescope randomly search the
sky while you sleep or eat dinner and with motion-detection software -
will snap a photo of the triangular craft flying by.... ah... dream on!
Yes, if you buy these from a manufacturer but WHATS IN YOUR WALLET (TM),
which is why I say: if you have the time, DO IT YOURSELF. It is much
cheaper, fun to make (if you don't muck it up) and you learn a lot and
is much more personally rewarding. Once you made your first one, you
might move into experimental mirrors/ccds etc and enhance your 2nd
telescope to bigger ones and you might beat the ones on Mt. Palomar
... uh.... maybe not :D.
Thinking about it though... I've often wondered if one might be able to
make a "mirror" with a parabolic hexagonal frame with a mirrored mylar
cover with a precision vacuum controllers for each hexagonal cells...
ah... never mind I am getting ahead of myself.
