A New Toy For My Birthday
Well, it's not my birthday yet... 3 more days, but I got an early gift of an intervalometer to do time-lapse photography. I've been interested in it for some time now, but lacking the tools.
I took two tonight sequences tonight.
Time-Lapse 1 - The First Video
This is a 20 or so minute sequence of 390 frames. Each frame is a 2 second exposure with a 1 second delay between frames for roughly 20 frames per minute. The video is presented at 30 frames per second so the video is only 12 seconds long.
The individual frames were (poorly) batch processed in Photoshop CS3.
The panning was done with my equatorial mount rotating RA at sidereal speed, but the mount itself was facing east to it would move the camera rather then track the stars.
It's my first one, so keep your expectations low.
I was close to my house and the roof pans into view in the top right. It wasn't planned very well.

Time-Lapse 2 - The Second Video
This one is 70 minutes or so and 1450 frames. The settings are the same as the first one, but it's longer that's all. This one is 29 seconds.

Time-Lapse HD - The Completed HD Video
This is the same sequence as the second video, but I "polished" it up a tad with some better processing for brighter stars and better color (I think) and put a little text intro and credit along with some audio. It's really nothing more then playing around in Final Cut and trying to make something that's pretty weak, not so lame. Not sure if it worked... LOL.
This one is an MPEG-4 with H.264 encoding and is presented in a flash player that also allows for full screen.

What I Learned
- JPEG capture was probably not a good idea. There are too many artifacts after stretching. When I do my next one I'll capture in RAW.
- Multiple sequences are better then one long sequence so the final "movie" is a little more interesting.
- 20 frames per minute seemed to translate pretty well to the video time. I think other guys use longer gaps and only take maybe 10 or even 5 frames per minute.
- I'm a total noob at this so I can't expect too much for my first attempts.
