The E200 is wonderful for astrophoto but the E100 emulsions are pretty nice too (not as nice blue sky though). If you need faster film (like for shooting fainter aurora) I'd grab the fantastic EPH P1600 (and shoot it at 1600). And astrophoto is the only kind of shooting where you want your films expired before use... (It usually makes the colors better, at least with the older Ektachromes ;-). There has been reports on successfully using ISO 800 and faster print films (Sky & Telescope mag) but I always shoot slides. There has been very nice emulsions for astrophoto but usually the best always end up to be discontinued...
