Extended Red

All this talk of SFX has got me wondering...

Years ago, I used a nifty film called SO-115, the SO being "special 
order". Came in only 150 foot rolls and featured extended red 
sensitivity. Was made primarily for astronomical work to capture red 
nebulosity, etc. Contrast was very high so a special home brew developer 
had to be used, called POTA. Grain was extremely fine; landscapes were 
awesome.

Finally, Kodak recognized what they had, renamed it Tech Pan, and gave 
us an easy to use developer.

I don't have any data sheets, but does anyone know how far up the 
spectrum this film extends?
