Arizona Sunset animated gif as promised

I recently posted an HDR image of a sunset and a few users asked to see more, so here is an animation from the series of photos I took to capture the sunset. The quality is slightly diminished because of the need to keep the file size down so it loads at a reasonable speed for people with slower connections.

This is a still from the start of the time-lapse I took

Here is a photo midway through the series of photos, notice how the clouds really start to light up and look like they are on fire.

The final shot as the sky starts to darken.

Thanks for looking
