A high (25,600) ISO time lapse experiment I did last weekend in Yosemite:

I'm amazed how crisp it looks, I was figuring at 25K ISO you'd be just looking at noise.

I used a 5d mark ii. I think one of the Nikons can do 25,600 ISO as well, but I don't know how well deals with the noise (for 25,600 ISO, the canon does a damn fine job of keeping the noise level down).
Here is a unprocessed shot (using default raw import settings) from the sequence:

That's awesome! What lense? I imagine your somewhere remote, like lake mead? I know when I vacationed out there years ago you could see the edges of the milkyway with the naked eye on a clear night. Something you can never see here in southern California...
Edit... just re-read your post, looks like you were in yosemite
I like the day to night shots as well! Very nice!

It was shot at Olmsted Point in the Yosemite high country on a night when there was almost a new moon (and moonrise wasn't until 4 hours later) so there was very little light pollution. I rented the Canon 24mm f1.4 lens for the weekend specifically because I wanted to work on astrophotography. Next time I want the 85 mm 1.2 @ 25,600.

You completely blow me away. There were so many shooting stars! All of the clouds forming and dissipating was a sight to behold as well. How long of a period did that 10 seconds take pace and how did you get the stars in?

It was done with 10 second exposures, at 12 second intervals for 250 shots.
I *think* the stars were mostly airplanes/satellites, but I'm honestly not sure. I can only see shooting stars with my naked eye for what would constitute one frame, I figured they would show up as such. They are showing up for multiple frames like a plane/sattelite would, they fade out at the edges like a shooting star would because at that high of ISO there is sensor blooming (like vignetting).

How do you make the camera shoot exposures for X amount of seconds and have it do that for intervals? I have the same camera. I think it'd be cool to do that. So shooting bulb isn't good to leave it open for say 40 minutes, but to have smaller exposures and take shots on intervals?
What setting do you do that with?

You can use an off the shelf intervalometer:

I use a custom built intervalometer that let's me do a bit more advanced stuff (bulb mode ramping) and I can build off it (for controlling my linear stage/rotary table, etc..). I used it for this shot, but I could have easily used the TC_80N3 to do the same thing.

I've seen awesome examples of multiple exposure Astrophotography. If you have an equatorial mount and you can do multiple lower ISO exposures and then post process them together, the results are incredible (as in, high detail/low noise).
This is multiple exposures because it is a time lapse, not for exposure purposes. The Milky way moving in the shot is due to the earths rotation (ie. I'm not doing a pan on a still photo). I chose to go this route as an experiment - I wanted to see if with heavy post processing 25,600 ISO was viable for serious astro work, as it opens up a whole new realm of possibilities for the type of time lapse stuff I want to do.

Oh, right. Not sure what I was thinking. I know bulb isn't video ha ha.
Tremont, what video editing software would you recommend for a mac if you had to pick one program. I'd like to start trying the video out on the camera more.
Your work has inspired me enough to want video editing software.
