Messier 35 and NGC 2158 in Gemini

Here is a wide field shot of the open clusters Messier 35 and the compact open cluster designated NGC 2158, both found in the constellation Gemini.  This is a huge open cluster that almost fills the same size in the sky as a full moon, it is about 2,800 light-years from Earth. As with any wide-field image of this open cluster, you get the added benefit of catching NGC 2158 nearby, not related to M35 as it lies about 9,000 light-years further away.
