Description This very large and faint (2.5 x .7 degrees) emission nebula is so named because the outline resembles the state of California and was discovered by E. E. Barnard in 1884.  The exciting star is Xi Persei about one degree south.  The estimated distance is 1000 light years.  Visual observers generally need a nebula filter (H Beta is recommended) to see it.
