6 Hours is a long time exposure

http://apod.nasa.gov/a​pod/ap080419.html Just happened to be browsing, when I stumbled upon this, lol

wow, 6 hours, haha. that is a long time. But that is pretty awesome!

I know, just can't do that on our Canon can we

That's quite cool. I'd wondered about stacking a bunch of pics to simulate 6 to 10 hours of star trailing, (if I could find a way to fight the dew), but over about an hour or so I think the trailing gets a little excessive. Thanks for posting the link to the image and saving me the trouble of trying to do something similar!

Thanks for the link. The time-lapse is cool too.

That is very cool and the video also !

Wow, 6 hours. The most I've ever managed is 1.5 hours - made some pretty nice star trails, but light pollution always kills it. The method of stacking multiple 30-second exposures together is nice too, just takes forever in front of the computer afterwards!

True, but with something like startrails.de you can set it running and go and do something else.

How did you manage that then???

actually, it's no problem at all (You just need to adjust the code a bit):
