I have never managed to get the atmospheric model to reflect what was visible at more than one zoom level. I think it's because they increase your light gathering power as you zoom in, as if you were switching to a bigger telescope to improve your aperture limitation, while in reality you usually zoom by changing lenses that keep the lowest visible magnitude the same.
