You can pull the film to ISO 400. Make sure you can find times for your developer.

With black and white, I'm actually interested in doing the development myself. So once I'm comfortable doing it by the numbers I'll probably give that a shot. Thanks.
Delta 3200 has long been regarded as an ISO 800 film that does well when pushed to 3200. You’ll be fine shooting it at 400 and, if properly developed, should yield some fine grain.
Head over to the Massive Dev Chart and find the times for your preferred developer + ISO combo.
That's a great resource I was unaware of! Thank you.
You could experiment with astrophotography, maybe try and catch some star trails with it.
That's something I hadn't considered. I'll look into it. My naive expectation is that I would need better optics.
Beware long exposure times. Rated ISO will drop (sometimes drastically) for exposures longer than 1 s.
