Here is an image of the open star cluster Messier 46 in the constellation of Canis Major (the big dog) taken in early March. Not sure why it took me almost four months to do something with it. Look closely. See that circular object just above the center? That is a planetary nebula known as NGC 2438. Sadly, it was recently confirmed that NGC 2438 is not really in M46 but in front of it. Still cool though.
