3Mb image, may take a while to load...



Thanks to Ronan for the txt for this, would have missed it otherwise!

Anyone know a better (& easy!) way to make a movie out of jpg's other than going to animated gif?

Cheers,
~Al

WOW ... that is the most impressive NLC image seen on these baords yet. Excellent work Al!

*takes hat off to Al*

Can I ask what length of time the animation covers?

Bart.

Thanks, should have mentioned the details.

From 11.30 'till 11.55, or rather 'till the battery died! 35 images more or less evenly spaced over that time. 100ISO, f3.5, exp 20-30 secs (auto).

Cheers,
~Al

Al - that's a superb sequence. It really does bring the whole thing to life. Well done.

Dave

Very nice Al!

WOW!, I love it, excellent animation there Al. 8)

*Agrees with above posters* Wow Al, that is a very nice piece of work! You have really captured the moment in that display Hats off to you!

As to your jpegs versus gifs... well, I don't think you have much of a choice. You could scour the net to see if such a jpeg 'compiler' exists, but as you can see from here, you have lost some picture quality because of jpeg compression for internet-firendly file size. If you go down the route of a gif animation, then you will have a smaller file but better preserved quality.

Great stuff!

It is a gif

The problem using gifs though is that you can only have 256 colours, so its not compression that makes the image look bad, its the dithering to only use 256 colours.

Perhaps a small MPEG movie would have been a smaller and better option?

Yup, but you won't like it. Load the images into iMovie, save, Done. Mac only solution though.

After reading up a bit I think imagemagick can do it easily enough on unix.

Is there anything Image Magick can't do?

3Mb mpeg this time. looks a little better.

That looks a lot better Al .... much more bang for your buck there (in terms of MBs)

Very Impressive!!! Thanks for sharing!

I saw this phenomena for the first time on 14th at vacation at my grandmother (Stord, Norway). Luckely i had my canon300d with me, so i took a couple of shoots with different exposure. Ill uppload the image once i get home on thursday.

Great animation!

Got home a day later

Here is the image:

Nice image Eric! You've caught some lovely wispy lines in there. Say, while you were there, did you spot any aurora actvity?

Thanks I must say it was even better to see it "live" Almost half of the sky was lid up like that.

No auroras spotted.
