So after reading up on and viewing as many time lapse videos as I could I thought I'd take a crack. Rule #1, make sure you check that the camera battery is fully charged
Oh well, here's a quick 9 second clip showing cloud movement while snapping at the Milky Way and then a quick moon rise which is what I was hoping to capture in all its glory but alas, that wasn't to be
Each image was a 15 second exposure with a 3 second delay between each shot taken with a Canon 20D & Sigma 10-20 @ 20mm.
I then used Apple iMovie to create and export the clip. Quite a useful learning curve nevertheless
