Long exposure time Lapse?

I have been messing around with time Lapse pro on my note 3 lately. It's pretty darn cool, and I got some nice footage. I most recently time lapsed a laser doing the liquid sky effect (circle instead of line though). I can post that if people want, but it didn't come out as cool as expected.

My question now is, how can I long exposure time Lapse? I want to take a time Lapse of the sky. But I need long exposure to get the stars on camera. So how can I do this?

From my knowledge of photography, you need a camera like a high end point and shoot or a DSLR that has programmable functions. Then you can set it to take a long exposure shot every interval you set.

If you have a decent Canon point and shoot (like I do) you might be able to install CHDK (Canon Hack Development Kit) onto the memory card (it doesn't affect the firmware, so theres little risk of damaging the camera). CHDK is like a unlocked OS for Canon cameras that gives them extra abilities including long exposure+interval shots. I've used it on my camera and it turned out pretty well.

Besides that, you would need a good sized and fast memory card, and a AC power cord for your camera if you wanted it to have power for a dusk to dawn time lapse.


If your good with video editing and have access to a high end software like Adobe Premiere and/or After Effects (theres a 30 day trial) and a very high capacity memory card you could set your camera to take a video. Theres many plugins for adobe editing software that would then take the video frames and "stack" them to create the equivalent of a long exposure photo (for example, if you shot a video at 30 frames a second, it would combine those 30 frames to create a 1 second exposure equivalent)

Hope all that makes sense and is of some use to you :)

Many cameras can do what you are wanting to do above. The key is to get a camera with decent manual control (not exactly common unless full frame DSLR) . However, surprising as it may sound, the GoPro Hero 3 black or Silver editions can do exactly what you want at 12MP per image at programmable timed intervals.

To do the star effect that you wanting, you'd most certainly need a full frame DSLR (for best results with lower sensor noise) and 1-2 minutes of exposure each exposure over several hours to create multiple frames (layers). You'd simply combine these layers as transparencies and adjust it accordingly within Adobe Photoshop CS6.
It's going to take some experimenting on your part, but I think you got a better idea now.

You can combine multiple frames from a higher end point and shoot and have a similar effect, however in low light you get lots of artifacts from sensor heating.

Below is an example of a (poorly constructed) timed (over 5min) long exposure. 2 frames total here. This was done on a point and shoot Lumix DMC LX3.
You'll notice just how blurry it is. My tripod moved very slightly during the last shot.
