I took these images during our last eruption
I headed there each day at 4:30 am, and then again after my shift with the eruption Crew was done. I usually stayed after work until midnight.
I went out three different times to try to see Comet Pons-Brooks. The photo below was my last try and I think the best. Shot from the dam at Branched Oak State Recreation Area in SE Nebraska. Pons-Brooks is the green-turquoise light in the sky near the left margin. The bright disk in the sky near the right margin is the Andromeda Galaxy. There is also a small fuzzy white smudge in the sky just left of center which is the Triangulum Galaxy. The lights at the lake are at the Marina.
I cannot rival @Yvonne's trip to Alaska, but we had this:
I took the color balance straight from the camera, but maybe it is still too warm or cold. I have never had to deal with any aurora photos before
They were all long-exposures and varied settings. I forgot my better manual lens, but I tried many diff settings from 1-10 seconds. I can go higher ISO on these kinds of photos because the noise removal tools are better than ever.
If you mean for WB? I shoot RAW, but I have tried a few diff temp, It seems cooler is best, like 3500-4000K.
We also got to enjoy the show in southern Michigan last night. I had heard about the possibility of northern lights but forgot all about it until a neighbor knocked on our door around 10:00 telling us to check it out. We walked up to the park to get bigger skies and were treated to our first ever sighting. The photos (just from my phone) were more dramatic than what we saw. I was intrigued by this and did some research. A camera's long exposure combined with how our eyes work (rods & cones - cones don't pick up much color in dim light) result in more colorful images than what we're able to see.
