IC 342



On Christmas Night, we had some early clear skies that gave way to clouds rolling in from the south.  Before that happened, I was able to image IC342, the sprawling island universe pictured above.  Normally, something of this size and brightness at 10 million light years away would be easily seen, but it happens to lie in the plane of our own Milky Way galaxy.  So, we are viewing it through the dust, stars and gas of our own galaxy which renders it much more difficult to view.  Think cosmic light pollution.  Normally, light pollution is the arch-enemy of astronomy, but when its coming from our own galaxy it creates quite a sight!
