Shooting Bracketed Exposures Quickly....
I'm experimenting with taking automated panoramas using a Gigapan Pro. For those who aren't familiar, the Gigapan is a robot of sorts that you hook your camera into and it shoots your panoramas for you using an external trigger. See http://www.gigapan.com for details. )
Anyway, I would like to bracket my exposures and be able to rapidly shoot a 9 bracket sequence with a single actuation from the Gigapan unit. I've seen someone else at one point shooting HDR videos be able to get the entire bracketed sequence this way but, for the life of me I can't figure it out.
The best I've been able to come up with is the self timer with a 2 second delay and then setting the number of exposures for 9 in one second intervals. However, that still gives me a 2 second delay that I don't really need as well as an interval period that is unnecessarily long.
Is there a better way to do this?

I'm not familiar with gigapan and don't really understand what your 2-second delay is for, but here's how I shoot brackets for HDR panos:
Set the camera to bracket and put release mode to Ch. It will fire the entire bracket with one press (and hold) of the release button. I don't know if that's compatible with Gigapan.
A 1-second shutter delay will reduce mirror slap and help you to not run out of buffer, but of course this slows you down. Put the camera in live view and turn off mirror delay, camera in Ch and it will fire the entire bracket with a press-and-hold without dropping the mirror. This is best of all worlds for speed and mirror slap, but you'll likely eventually run into full buffer which slows you down. And LiveView doesn't return until the buffer is clear, which is a problem if you're positioning the camera manually but probably not for gigapan.
Ideally 2- or 3-stop bracketing could solve or reduce the buffer issue but Nikon remains asleep at the wheel on that one.

Yep, your idea works! Thanks!
I was afraid that if I put it on Ch that if the camera was actuated too long, it would continue and begin a new set of bracketed exposures. Apparently I was wrong and the camera stops after the first set of bracketed exposures. The Gigapan lets me program "bulb" for different lengths so a 3 second "Bulb" lets me capture the entire sequence of 9 bracketed exposures.
The two second delay was if I was using the self timer. For some reason Nikon doesn't let you program the self timer to activate the shutter with delays shorter than 2 seconds. Along those lines, one of the things I really like about the D800E is that I can program a number of exposures (and delay) into the self timer. It came in super useful at Yellowstone this summer with the family.
