Seeing the tail of a comet through night vision is spectacular.
Never seen one. Living in a metropolitan area such as mine, one never gets to view the night sky as it should be.
I've had the fortune to spend several pheasant hunting trips to N.W. Kansas and stayed in a farm house where the night sky was completely devoid from any city light corruption.. It was magnificent........And being in the fall, while you couldn't see them because of the darkness, you would hear the honking of the migrating geese high up in the sky.
