I really like this design as its very portable and easier to build then the lightbridge.

Very expensive though about 5000$ US.

I also like the other Scopes they have for sale.

Note the schipfigler, this is the first commercialy designed one I have seen.

sure is an ugly duck.. but very clever all the same
I've often thought of taking an angle grinder to my ota to
make it more portable.

Graham,

I know Dave was exploring a section design amd I think Lee has actually taken a grinder to his scope. I think this design is great because you could incorprate a very small section that can be removed to bring the primary forward to achive photographuc focus.

You could also use the Sealed Mirror section to have a fan on the lid to create a closed cooling solution to precool the mirror.
