Emanating from the galaxy are many filaments of hydrogen (red).

Crawford is the featured speaker for April at the Nevada County Astronomers. He will provide a colorful tour of the universe using long exposure, high-resolution astrophotography.
There will be a "behind the scenes" overview of the equipment, challenges and conditions needed to produce presentation high-quality images of the deep sky. Crawford will also present the latest results of the search for galactic cannibals who leave behind rivers of stars. The talk is in the Community Room of the Nevada County Library at 7 p.m. on Wednesday. The public is invited and there is no charge.
