13 seconds. 3200 I think.
Much longer than that and the noise goes up and the stars get blurrier.
I am curious about experimenting with combining 15 2-secod exposures, or
something like that.

The difference is film has no chance competing with a D700 at high ISO. I
believe that would be 13 seconds. I remember shooting Northern Lights in
Canada back in the early 80s on Kodachrome 64 and a Pentax LX and 50mm 1.4.
I think the exposure - picked by the camera reading off the film (the LX was
one of the first to read ambient exposures reflected off film) - was about
30 seconds.

Um.that's for Windows, isn't it? Let me see if I can check the

much shorter than I anticipated anyway. I have a shot of northern lights /
aurora, spent about 8 minutes with film and wouldn't show up spectacularly
like that, suffering a massive reciprocity failure.

Do you have Opanda?

Nice to have. A right click leads you to all of the data.

Hi Eric
Thanks again for the Audio help.
If you look at this at 100 percent you can see 4 meteors, faintly. All
near the center of the screen sort of.
Best,
JO

Jay,
Thanks for your interest.
This is a low-rez version of a NEF I shot with the D700.
There are a couple of faint trails near the milky way near the center of
the image, and a couple of smaller traces on the left center. You have to
enlarge to 100 percent to see them well.
Not show stoppers when it comes to meteors - these were accidents while I
was shooting the milky way hoping for a meteor. I didn't see any of these
the camera caught.
Best,
John

An engineer, a physicist, and a statistician were moose hunting in northern
Canada. After a short walk through the marshes they spotted a HUGE moose 150
metres away. The engineer raised his gun and fired at the moose. A puff of
dust showed that the bullet landed 3 metres to the right of the moose. The
physicist, realizing that there was a substantial breeze that the engineer
did not account for, aimed to the left of the moose and fired. The bullet
landed 3 metres to the left of the moose. The statistician jumped up and
down and screamed "We got him! We got him!"
