>>2627122>>2626868There are a few very bright deep sky objects that are fine with low ISO and short exposures. Never tried with film, but I'd give a try at M57 and M27 (and of course M42 in winter, huge and fucking bright).
Also, most of the globular clusters should be fine, even if they are less visually interesting. (pic related, M3) This is like a 10 or 15 second exposure.
