Do you wont trails or points? For points you have to keep the
exposure fairly short. Using a 45mm lens, I got slight trails from
10s upward. Longer lens would trail sooner.
Using same 45mm lens, f/8 and 100ISO Ektachrome, 10s produced
wonderful colours and barely noticeable trailing.

Expect trails around 1-2cm long on a 10x15cm print if you expose for 30sec.
Anything from 2 seconds to 6 hours will do. You will have to LART the
lab beforehand or they'll say "there was no image on your negs".
