ICELAND NORTHERN LIGHTS AURORES BORÉALES TIMELAPSES

My trip to Iceland was in September 2023, where we had several nights with temperatures close to zero and almost no moon. Found out that my favourite setting for the camera I am using is to set my timelapse to a 4 second exposure time, snapping a new photo every 4 seconds. Lenswise, of course I would have like to be able to afford the Sigma 14mm f1.4 DN Art Lens, or even a budget-friendlier Samyang 14mm f2.8 (since fx3 12 800 ISO compensates well enough for the loss in f-stop). Had to use my all-around Sony 24-105mm FE F4. If you ever had the chance to capture northern lights timelapses, any kind of exprience sharing, tips, gear tricks, etc is welcomed in the comments. I am always in awe in front of beautiful astrophotographies from peers and reckon there is always more to learn in order to perfect one's craft. Good night and Good Lights !!!
