@StUone7: the city glow isn't that bad in the shot. Much better than we have here. If you take a long enough exposure, city glow will always exist in most areas. I took a shot in sedona for several seconds and ended up getting city glow from a city 45 minutes away.
Yea now that you mention it same thing happened to me down in Joshua Tree Park. I guess I got a little spoiled by my backpacking trip to Desolation Wilderness haha. I've learned better technique since then though.
