View Full Version : Rich open cluster IC 166

2011-Dec-22, 12:51 AM
IC 166 is an open cluster in Cassiopeia. It is about 10,750 light years from us by one paper I found. The WEBDA puts it at 13,000 light-years. Pinning down an open cluster's distance is still beyond the science in most cases. It's age is estimated to be about 1.32 +/- 0.43 billion years. Wide field images show it is seen at the edge of a weak dark nebula so stars are likely reddened. It's age plus the dust likely account for the rather red color of most of the stars in the cluster.

I had to severely crop and reduce the image then compress it more than I like to fit it in bandwidth limits. A lot of color and the rich field were lost.

Very nice. Simple and yet, very beautiful. A pleasure to see amongst the norm of nebulae and galaxies.:)

Even with all cropping it looks great. Do you have any location with the real size (You can upload full size to Picasa for example).?
