A green sky...Anyone got any ideas?
I was out tonight, it was a beautiful night, very little cloud, moderately good seeing 6.5 -7 out of 10 and a bright just past quarter moon. I thought I'd do a messier hunt and try to track down some globs. (what else can you do with a moon like that?) Cold and very dry (which was strange after the rain we've had during the week) no dew anywhere. Even after 2 hours my OTA was bone dry.
At around ten o'clock I noticed something strange, every thing looked green, as though I was looking through green celophane. The sky was noticably tinted green, the stars looked greenish, the few clouds looked green, even the moon had a greenish cast to it. This was with the naked eye and not through the scope. It was too hard to tell through the scope and I couldn't see the moon through the scope where it was set up. The strange thing was the street lights and house lights looked normal.
Does anyone have any idea what might have caused this? It looked amazing.
