Today's Astronomy Picture of the Day.

Ain't gonna do that with digital (unless you do it the way this guy did).

WOW, simply stunning. This gives me more inspiration to attempt a star streak photography.

Thanks for sharing

Hooo man, 11 hours! Jeez, if we did that at YRS, it would look like daytime ;-)

Holy cow! 11 hours! Bet that'll burn a sensor!

If you read it, you'll notice he combined 128 5-second exposures or something along those lines.

Yep, but it was 128 five minute exposures.

Too much light to try it from where I'm at, but now I wonder if the Canon software can be set to do consecutive 5 minute shots...

My biggest fear would be leaving the camera out all night unless I was really far away from people. And if I was, I'd probably be able to actually see the stars.

And quite a few batteries. Musta been hooked up to AC.

That's what I meant...what'd I say...seconds? It's too early.

This rocks. Great shot!

Undercaffeination is a very *bad* thing ;-)

You don't need software to do it, just the Canon TC-80 Timer Controller.

Does anyone know if this is possible?

As Spazmo99 posted, the TC-80N3 is all you really need for camera control. It can be programmed to do an outrageous number of things. Another issue, though, is camera power. For that length of continuous image acquisition, I'm guessing that even a battery grip won't be near enough. An AC adapter (or ac adapter and inverter if in a remote area) would be required.
Finally, in many areas dew is a problem. It's easy enough to keep dew off the camera by covering it, but keeping the dew off the lens is another matter. Astronomers do it by gently warming the air over the front element using an electric band heater on a "dew shield." Something similar could be rigged on an SLR.
