Share the stars with these greeting cards featuring images from the NightScapes image collection! These star trail images were created by compiling hundreds of single images sequentially taken within 2-3 hours. When stacked together they create lines showing the path of the stars in the night sky as the Earth rotates. 
 
Set of 8 greeting cards (2 of each image), with envelopes  |  5x7 folded  |  blank inside - perfect for any occasion!
