Northern Lights big style

On Thursday 27 of February we had a fantastic aurora here in Östersund with lots of red colors. I took the opportunity to make my biggest panoramic image so far. The image below consists of 23 separate images with a 360 degree coverage from the horizon and all the way up to zenith. The original image has a resolution of 25,000 x 14,000 pixels at 300 dpi and with a 16 bit color depth. The file size of the finished Photoshop file with all 23 layers is 13 Gb. I've included a 100% crop from the original image to give you an idea of the resolution in the image. The container is marked with a red square in the image.
