Usually, when I've taken a collection of photos of a particular DSO, I've noticed that the brightness of the images changes or jumps. This is usually seen as the histogram moving to the left and then back to its starting place as I cycle through the images. Does this happen to anyone else? What might cause this phenomenon?
