Wow, that's cool. I'd never heard of the Hyperstar before, the only problem I can see is my DSLR would block half the aperture. Haha, I just measured it (550D with battery grip) and its nearly 6" wide! 3/4 of an 8" tube.
I think I'll stick with Newts for a while then, I should do SOMETHING with the 15 lineal feet of carbon fibre I bought after all.
