Re: [ATM] a lightweight 12' "hat box" travel dob, 20 pounds.

The platform! 
how extremely simple!
Your platformdesign is extremely lightweight, minimaltistic and I think
very stable, because the wheels are placed vertically ( instead of 50
degrees ).
Most important: it is easy to built (as far as i can judge).

And I almost forgot your telescopes.
I am really impressed: size,weight, look and feel:  everything is
"perfect" 
Very inspiring.
Good luck with your projects Pierre.

Hello everybody,

Here is my latest completion, a lightweight 12', f/d 5,  travel dob,
20
pounds, all included.

Easy to carry in a bag, for airflight or a trecking in the montains.

I tried to make it as light, compact and minimalist as possible. I will
call
it : "La libellule" (dragonfly).

 Please note some particular points;

- When disassembled, all parts are put together in a "hat box", 42 cm
diameter, 12 cm height.

- The ring base is used as a mirror box.

- The lightweight, low profile and simplified spider,

- The lightweight helical crayford focussor (60 g),

- The truss fixations: made in duran, with double articulation.

- The ring  flex rocher and ring base system.

In the pictures, the dobson is shown on a very low profile and
simplifiedc
equatorial platform (4 cm height).which is still waiting for a drive.

All details and pictures, as well as pictures of other dobsons I made, 
are
here on my web site:
