It is 30 light years across and lies at a distance of 11,960 light years from Earth. It has some resemblance to the Norse god's helmet and so it is named. (source: constellation guide).
I was able to shot this over four nights beginning last Thursday when we finally had some clear nights. Some of which were above freezing. I had some guiding issues after the mount did the meridian shift on the first two nights for some reason but I was able to get four hours decent exposures.
