Stars and Satellites

This is a 27 minute exposure using my iPhone of the sky this morning at around 3am. There were meant to be meteorite showers over the next few days and I hoped to capture some. I think most of this are just the curves of stars and the straight lines of passing satellites. 

FYI the stars that are blue are hot and young whilst the yellow/red ones are cooler and older. I increased the colour saturation of the image so that the colours stand out. My research tells me the colours are based on blackbody radiation physics*, not image editing. Everyday a school day... 

* I have no idea either. ;o)
