Most everyone knows I love staying up at night to shoot the Milky Way and the stars. Once in a while I will play around after shooting the Milky Way and shoot some star trails too. This is more of a fun shot, as you never quite know what you will get.
This is a 45min single exposure. Most often today Star trails are stacked from multiple shorter exposure photos, but I wanted to play around and see just how long I could shoot without getting a bunch of noise from the sensor overheating. Ben might know better, but I think the temps were still in the low 80's at night, but whatever it was, it certainly wasn't cold at night. So shooting a 45 min long exposure would definitely be a test for the Nikon D850.
Doing a quick review after I shot, it all looked pretty clean. I was shooting at ISO 200 for this, and at f1.8. But when I got home and I looked at it at 100% on my monitor I found that the ground layer was just peppered with random white dots that had to have been from the sensor overheating. So the ground layer was really unusable, and for a few days I just put this to the side. Then today I decided to give it a try and see if there was something I could do to get rid of all of that sensor noise. And I am glad to say I did! I need to write up a little tutorial on it, but it was really super easy. And then I was super glad.
So now on this, there are 4 or 5 faint trails going through this from airplanes. Since this is just a for fun photo at this point, I decided not to tackle that yet. If I get serious about it I will go clean those up.
