If you can find the Ektachrome 200, go for it. Elite 200, E200, Ektachrome 200 are all basically the same thing, as far as astrophotagraphy goes.
Fuji Acros 100 (black & white) has good reciprocity, it cn be hypered, but it has low red response. Otherwise, it seems to be similar to the old Tech Pan.
Fuji Sensia 400, again, weaker red response.
Fuji Provia 400X, weaker red response, but good blue.
If you can find some old Fuji Provia 400F, that has great blue and red response.
I have had decent results with expired Provia 400F and E200 film (35mm), though my scans don't tell the story, my scanner is a flatbed. They all seem a bit purple to me, even after processing. This is from Fuji Provia 400X, the new stuff.
