Hi,

thanks for sharing. I saw a similar time lapse of a starry sky  (can't find it anymore) that slowly turned into a star trail video. So, initially you could see individual stars moving across the sky (like in your example) but then they smeared to rings. How would the work-flow for such a result look like?

Maybe by merging frames, 1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7 etc.

I quite like this, I was planning something similar but wanted to get more scenery in.

The issue is how long each exposure is. If you want the stars to look good with no trails you need a good fast lens.

can you share the settings you used? iso/shutter/f etc?

The first of many attempts,

Hi, this is OK. Tell me what shutter speed was used? I guess no longer than 2-8 sec. In case of moderate wide angle (18mm) you can easily use 30sec to get more light and stars will not be blurred much and you will get much more details and stars. It is also good to move more far from city lights.

Thanks for your opinions, it was hard, after many attempts, as the light was constant, no flicker problems, with many stars i just take photos for two hours, every 1 or 2 interval seconds, (ML) and then Lightroom 4.1, but using the LRTimelapse pro presets, very good, because the default ones in the LR has some quality issues.

With my canon 60D crop factor camera, I used the 600 rule, 24mm *1.6/600= 15.6 shutter exposition, (approximate value in camera) for avoid star trails, (believe me, it works)  I used my Tamron 17-55mm, with VC off and manual focus (obvious), focusing to infinity,  2.8 lens aperture, iso 400 and 3200k WB and some post processed work, especially for correct the wb and noise and other things, is up to you,  i´m still practicing. I´m doing a storm passing clouds right now and a sunrise, but i´m kinda worried about my shutter part life, I read that only have 150k shoots,  =( I'm definitely going to still trying TL´s, I'm obsessed with this.

Please correct me if i´m wrong.

Cheers!

Thanks for all that.

I just got a f2.8 28mm lens I am looking forward to trying.
I was going to use ISO 800 maybe 1600 and 20 seconds.

For time lapse I have been using Movie mode and the fps override. Its much kinder on your shutter!

For the night sky shots though I am doing single long exposure and not time lapse yet. Will see if I can get something good with movie mode and stars.

Don't you want to use FPS override? I saw some videos who uses this technique in ML v2.3 and lower.

You should definitely try FPS override if you don't mind the lower resolution

You will record a video (limit is 1080p), when you would take pictures, kill your shutter, the number of megapixels is the limit.

Can you please show me how can i use this ML feature?
Title: Re: First Sky Stars Timelapse

But you can only open the shutter for 2.5-5 secs? Doubt that it is long enough for stars and will be a bit noisier too.

If it's full moon, it may work.

At the end of this timelapse I've used 15 seconds at ISO 400, f4: http://vimeo.com/48861358
