When I am working on such delightful celestial objects, I sometimes think astrophotography is a pre-stage of poetry. The astrophotographer, invests all his experience trying to interpret a fact into a shapes and colors, so a poet tries to interpret his emotions after looking these pictures into wonderful words. /px
