Yeah, but stop down a bit for sharpness.

The human eye has amazingly poor colour response at low intensities.
You'll find that on film, the colours of starlight are splendidly
vivid and varied.
One thing about slides vs. negs for starfields---on my slide shots I
saw the constellations wonderfully, because the dimmer stars hardly
registered. On negative film you have a much wider contrast range,
and get considerably more stars.

Moon is tricky. Getting good moon shots is *much* harder than
starfields. Getting moon shots with anything else recognizable is way
hard.
Have you seen Adams' famous "Moonrise, Hernandez, New Mexico"? That
negative is almost unprintable. Only split intensification and thirty
years of experimentation got the prints that sell for thousands now.

Unless you can go to your lab and say "G'day Jim, how's Cheryl and the
kids? Got some star-shots for you today, see you tomorrow as usual?"
you won't get happy results from negatives.
The "uncorrected" print is a myth, IMAO.
