Thor,
You need to look at the negatives yourself. The lab will have looked
at the frame and said it is mostly blank which it will be as it is
mostly black sky. You need to look at the detail around the stars
which will be very small specks on the film. If the lab does a decent
contact sheet then you could evaluate from that, however there is a
good chance they will scan + print which will be of little use as the
scanner will auto set to who knows what when it sees a night sky.

I had the film developed today, and asked the lab to run a
densitometer on it to see how the exposure looked.
They called and said the negs look blank, very thin, although there
might be a hint of detail on a few. He’s going to do some more
looking and try and print a few contact sheets just to see what’s
there for me on Monday. His best guess was that I’m 2-3 stops at
least from the bottom end of where my exposure should be, which would
mean 6+ minute exposures, which means light streaks and trails, which
I don’t want.
So how did people make these amazing night shots of the milky way and
starscapes, or landscapes with a starry sky above when using film? I
don’t mean dusk, nor do I mean astrophotography through a telescope.
Maybe it’s something that only works on digital?

Update on my night photography attempt. (Nothing has been developed
yet)
Went to Joshua Tree, found a place in the middle of nowhere
(literally) that was dark, pointed the 6008i2 on it’s tripod up at
the sky, and used the “Ultimate exposure calculator” as the guide.
It said night sky with some moon is about EV3 or 4, which gives a
30 second exposure on 400ISO film.
I loaded up Kodak Portra 400 and made a roll of exposures at 15
seconds, 30 seconds, 60 seconds and 120 seconds, some with a
foreground, some only of the sky. The lens was the 40mm Super
Angulon, set to f4 for all shots, focused on infinity ("and
beyond!”).
After quite a bit of searching on the web and looking over Kodak’s
own data sheets, they offer no info about reciprocity for this
film. Frustrating.
Some general recommendations I found were to avoid exposures over
30 seconds due to the motion of the earth, use a wide open
aperture, use a wide angle lens.
I’ll drop off the film soon and see how things look.

I took several starry sky photographs, the last one taken last
year with the Milky Way as background using the Rolleiflex 2,8F
Planar with a TMAX 400 film (the batch showing the paper back ink
leak problem) Exposure time was about 25 minutes at B, f:4. It's
necessary to keep in mind the moon to avoid it. I think I read
somewhere that SLX/6000 cameras manuals describe a method for long
exposure times selecting a shutter speed T mode and switching Off
the camera:

<mailto:dmarc-noreply@xxxxxxxxxxxxx>>: I plan to go out to the
desert next week, and have been told how dark it gets so that you
can see starts, planets, even the milky way quite clearly, with no
light pollution whatsoever.
Which begs 2 questions:
1. Is the 6008 even suited to night sky/starscape photography? I
have the 40mm/4, 90mm/4 and 150mm/4 available. Haven’t been able
to find my 80mm/2 lens. I have a tripod. I can buy whatever film
would be most suitable (B&H, Adorama, Samy’s).
2. If so, what are some exposure guidelines to get good results?
What film?
Thanks for any tips and feedback.
Thor
