Great idea and execution. I hadn't considered stacking flowers like this with a night sky shot, especially one of aurora. Congrats on a dream come true.
Wow! You have created something unique from among the mass of aurora photos worldwide. Well done! Such an intriguing and feel-good vibe, definitely earns my vote 👍🏼
This photo has eluded me for over a decade. I have wanted to take a photo where auroras and summer meet. But It's very difficult, because when summer comes, dark skies vanish. So, the window is approx. two weeks to get this kind of photo.
Then again, its not possible every year. The auroras have to spread to the southern sky, because northern side is too bright. So, the actual window for a photo like this is maybe a couple of times in a decade, only during the strongest geomagnetic storms.
I have a couple more stacks waiting for processing.
Before this moment, there was a bright red /pink arc close to the horizon. That pink was clearly visible to the naked eye. Seeing red color in auroras is very unusual.
