This is 150 images stacked, starting at sunset & shooting for 10 minutes into twilight.. I set my timer up to take a photo every 4 seconds and I used Startrails.exe for stacking using the lighten blend mode. It’s always exciting for me as I wait for the layers to finish processing. I guess my excitement can be compared to that of how a child feels when opening a gift on Christmas morning. Each outcome is so unique in time stack photography and you never know how it will turn out but when the skies are right for it you can pretty much guarantee it will look pretty cool.
