I was down the coast this weekend. It was a dewey night, but clearish so I set the Canon and kit lens on the tripod, framed the next door neighbors roof for a reference point, and proceeded to manually trip the shutter every thirty seconds (using my wristwatch) for thirty second exposures.

The lens kept dewing up, but I very carefully continued to wipe it with a tissue while trying not to move it between shots.

I think the dew actually added some nice effects, so next time, I wont allow it to make me give up short, just persist despite the varied shots.

Hope you like it. I am definately going to do more of this up in the drier air of the Canberra mountains.

Great sequence! For a northern dweller it was a little disconcerting to see the sky moving from right to left and then to see Orion upside down (for me at least)....wow, I guess the Earth is round after all. (IMG:http://www.observatorycentral.com/style_emoticons/default/tongue.gif)

Nice... But yeah, strange watching it upside-down and move backwards! (IMG:http://www.observatorycentral.com/style_emoticons/default/smile.gif)

How long was the time lapse?

30 second exposures every thirty seconds is one image every minute. 67 images equals 134 minutes total.

Next time I am going to the top of the mountains not far from here and try 30 second exposures with 10 second intervals.
