NGC 7380

Here a 50% version, or 100% version.

NGC 7380 is an emission nebula in Cepheus. It's main color is red, but in the central part there is a blue-purple color. Moreover a small patch, encircling one star in the center, is white-light blue.
This image is a test made with the new Canon 60Da and my usual setup. It needed all the night to collect this exposure.
