I love shooting stars and nightscapes, sadly though I hardly ever have the patience for it. Not only that but since I live in the Pacific Northwest the nights that I have to choose from for shooting are limited due to constant rain and cloud cover most months out of the year.
Regardless, I came across this very well done tutorial on doing star trail photography from Tony Northrup. Its promoting his book, so take that into mind – but the tutorial itself was very helpful to me when I was looking to learn more about shooting star trails. In the video Tony goes from how to choose good nights to shoot the stars all the way to how to process them. You can check it out below.
