Astrophotography / I tried a few different stacking programs with stacks of a dozen images. The stacked results are almost identical to the individual shots. Do you need to take a LOT of images to tease out nebulous details? I'm just not seeing any major differences and figured I'm not taking enough frames to make it work. I can make out the objects but the stacking doesn't seem to make a difference.
Would a single exposure with tracking offer better results?
